Being a hero doesn't mean you're invincible; it means you're brave enough to stand up and do what's needed.

–Piper to Jason about being a hero, in The Mark of Athena.

Piper McLean is a Greek demigod, daughter of Aphrodite and Tristan McLean. Piper is currently the head counselor of the Aphrodite's Cabin, after challenging and defeating Drew Tanaka who became the head counselor of the Aphrodite cabin after the former counselor died in the Second Titan War. She is the former girlfriend of Jason Grace and the current girlfriend of Shel.

History

Early Life

Piper got her name from her Grandpa Tom, who noted her strong voice and hoped that she would one day learn all of the great Cherokee songs, including the Song of the Snakes. As opposed to many other children of Aphrodite, Piper was never very focused on her natural beauty and has a somewhat tomboyish style. At one point, she helped her actor father research Greek mythology (for a role her father was about to take on in a film) and learned quite a bit of information that she found interesting.

Her father would also tell her old Cherokee stories he heard from Grandpa Tom. From time to time, Piper and her father would play a game called "Any Three Questions," in which Piper would ask her father any three questions of her choice and he had to answer them without lying. Her main intention was to find out more about her mother who apparently left after she was born. However, Piper wasn't able to learn much about her mother. She later recalls how her father had driven Piper past a meat-processing plant in Chino when she was little. The smell had been enough to turn Piper into a vegetarian. Ever since then, just the thought of cows made her ill. As Asclepius would later reveal, Piper had broken her arm when she was six after falling off a horse.

Going to Boarding School

In addition, Piper has always had the ability to charmspeak and uses it (not knowingly) to gain her father's attention by "borrowing" things from salesmen, causing her to get into trouble with the law when the people report her for stealing. At one point, she talked a car dealer into giving her a BMW and drove it away from the lot. She only stole items because she wanted attention from her father, who she believed wasn't spending enough time with her. The dealer pressed charges for theft after Piper took the BMW and realized that he had been tricked. Her father's assistant, Jane, made a deal for her to be sent to Wilderness School, a place for delinquent kids, instead of going to jail. It was there that she met Leo Valdez, and the two formed a friendship, she even trusted him with the truth that her father is the movie star Tristan McLean, something that she keeps a secret to most people.

Piper and Leo's backstory is a rare one since they are the only two known demigods who meet and befriended each other before they even knew they were demigods.

Mist History

Leo Valdez and Piper were both given false memories of Jason Grace before he arrived at the Wilderness School. In these memories, Jason, Leo, and Piper had been friends for about three months after Jason first arrived. Piper tried to get closer to him and the two eventually watched shooting stars from the school's roof and shared a kiss. They began dating a few weeks before the events of The Lost Hero and Jason was also Leo's best friend. This reality was proved to be fake when Annabeth asked Piper some basic things about Jason she doesn't know, like his last name.

The Lost Hero

Piper appears the first time in the Wilderness School bus driving towards the Grand Canyon on a field trip. She is holding hands with Jason, who she believes is her boyfriend because Hera had given her false memories.. She's the first to realize something is wrong with him (Leo at first believes Jason was playing a prank on them), and is devastated when she finds out that Jason doesn't remember her. This is because Hera erased his memory, as well as Percy Jackson's, and it is later revealed she used the Mist to try to trick Piper. Shortly afterward she is torn away by Dylan, who declares her his partner for the school work, but keeps flirting with her the whole while.

As a strong storm starts, Piper and Dylan help the others to leave the sky-walk, until only she, Dylan, Leo, Jason and Coach Hedge are left. As Piper loses control of the door, which suddenly seems to be magically locked, Dylan reveals to be an anemoi thuellai (Roman form ventus), a storm spirit and a child of the storm giant Typhon, and battles the four of them along with his fellow venti (plural form of ventus). Piper tries to fight the venti with Jason using Hedge's baseball bat as a weapon, but when she hits Dylan to prevent him from taking Jason, she is thrown off the sky-walk. Jason jumps after her and saves her, stopping in midair and catching her before flying back up safely to the skywalk.

Coach Hedge, her protector.

Dylan takes Hedge away after Hedge saved Leo, who had been knocked off the sky-walk in the battle. The three are picked up by a chariot, driven by Annabeth Chase, daughter of Athena, and Butch, son of Iris. Soon after, they crash land in a lake at Camp Half-Blood, Annabeth gives Piper a tour of the camp and helps her pick out her weapon, a dagger previously owned by Helen of Troy, called Katoptris (Ancient Greek for "looking glass") that has the ability to show much more than the user's reflection when looked at, such as depictions of the near future. Later that night, Jason is tasked with picking two others to come on his quest by Chiron. After he picks Leo, Piper says she has to go too while trying to compete with Drew to be on the quest. She was then claimed by Aphrodite, much to Drew's chagrin and is chosen by Jason. Later she becomes friends with two of her half-siblings, Lacy and Mitchell, and learns how to use her ability to charmspeak. However, Drew, the head of the cabin, keeps everyone under her thumb with her own ability to charmspeak and makes Piper so mad that when asked who her father was, Piper admits he is Tristan McLean without thinking about it. When the other members ask if it is true and she becomes the center of attention in the cabin, Drew tells everyone that it is a lie, but rips his poster off the wall a short time later. Piper claimed she did not like to play the "famous dad card," and felt bad and regretted what she did after using it against Drew.

The next day, Piper, Jason, and Leo take Leo's new "pet mechanical dragon," Festus, and begin their quest. They arrive in Quebec and they meet Boreas and his children, including Khione (goddess of snow) and the Boreads (immortal children of Boreas), where they get on a bad note with them. Later, while Piper is sleeping, they fall off the dragon, which malfunctions and they crash land into a supposedly abandoned car factory in Detroit, which turned out to be the residence of three grown Cyclopes. Jason and Piper are held captive and knocked out, but Leo rescues them and they find out he has fire abilities. After they escape, they stop to rest, but then they meet Medea, a sorceress and charmspeaker, who nearly causes Jason and Leo to turn against each other, however Piper gets them out of the trance with charmspeak and they fight Medea. They also find Coach Hedge and the storm spirits to trade with Aeolus. As they escape, the building explodes.

Soon, Festus crash lands again and they fall in front of a mansion. Inside they meet Midas and his son Lityerses. Jason helps himself and his two friends escape, after Leo and Piper get turned to gold, by calling down lightning and defeating Lit in a swordfight. After they turn back to normal they run into Lycaon (the first werewolf) and the rest of his pack, but the Hunters save them. Thalia Grace, Artemis's lieutenant and Jason's sister leads them to Aeolus's palace before getting separated when the ice vapor bridge melts after Leo gets too excited about a theory he formed about Jason's appearance and Percy's disappearance. They meet Mellie the aura, who has a huge crush on Coach Hedge and who ends up marrying him and having his son whom they named Chuck. The trio meets Aeolus who, in the end, tries to kill them on the order of Gaea. When they escaped, winds shot them to California. They confront the giant Enceladus to rescue Piper's dad, Tristan McLean. They manage to defeat the giant along with the Earthborn with help from Zeus, but her father is mentally broken and Piper is forced to give him a potion that Aphrodite had given her, one that will erase all his short term memories. Piper then allows the medical team to take her father away while she charmspeaks a pilot into letting them borrow their helicopter to travel the wolf house to rescue Hera. They find out that Khione has been spying on them and that she plans to help the rise of Porphyrion, the giant king. Leo battles against Khione and manages to force the goddess to retreat with the help of his fire powers until Porphyrion rises and Jason keeps him occupied while Leo tries to cut Hera free. Piper lulls Gaea to sleep; showing her amazing skills in charmspeaking.

After their quest is completed, Piper, Jason, and Leo return home to Camp Half-Blood. The next morning, Piper challenges Drew to a duel to be head counselor, but Drew grudgingly backs down for she does not wish to fight Piper since she survived an extremely arduous quest. Later Piper video chats with Gleeson Hedge, Mellie and her dad who remembers nothing of his ordeal and thinks Piper is in a special school. Then Piper shares a moment with Jason, in which she accepts that she loves Jason, but she doesn't know if he feels the same way. Later, she heads into the woods with Jason, Leo, Chiron and the Hephaestus' Cabin, as Leo shows them Bunker 9. As the book draws to an end Piper hears Jason say that it is most likely that Percy Jackson is at the Roman camp, called Camp Jupiter.

Leo Valdez and the Quest for Buford

Two months after the events of The Lost Hero, Piper and Jason are summoned by Leo Valdez to aid him in recovering Buford, the walking cabinet who wandered off carrying the syncopater for the Argo II. Without the syncopater, the ship will blow up within an hour, taking Cabin 9 and a significant portion of Camp Half-Blood with it.

They then set off to recover the object, but their path is complicated by the appearance of Maenads, cousins of the naiads and dangerous followers of Dionysus. Piper utilizes her charmspeak to confuse and delay the Maenads until the appropriate moment where Leo develops a trap to capture all of them in one sweep which frees him to install the syncopater on the Argo II and prevent its imminent explosion.   

The Son of Neptune

Piper makes a brief appearance in a dream of Percy Jackson along with Jason Grace and Leo Valdez as they construct the Argo II though Percy at that time was unsure who she was though he thought it was likely that she was a friend of Jason. Later, her voice is heard calling Leo a "repair boy" when he asks her what his title is during a video message to Camp Jupiter, asking them not to blast them out of the sky. By the end of the book, she sets out to meet the rest of the seven demigods at Camp Jupiter.

Earlier in the book when Polybotes and the Giant Army are marching toward Camp Jupiter, Ma Gasket is shown to have reformed and joined the army. She complains that the purple and orange ones destroyed her home and she wants revenge against Piper, Leo, and Jason. While the name Jason sounds familiar to Percy, Hazel, and Frank, they don't know who Leo and Piper are.

The Mark of Athena

Piper is on the Argo II, practicing her lines for when they land at Camp Jupiter. While using charmspeak to talk about lowering their weapons and talking, Annabeth Chase almost put down her knife to have a talk showing the strength of her charmspeak. When Terminus arrived she tried to charmspeak him but instead, being a god, he was unaffected and instead tried to slap the knife out her hand, despite having no arms. He is then calmed by Jason.

After the welcome feast Camp Jupiter begins, Leo (who was possessed by an Eidolon) begins to attack Camp Jupiter. Jason goes unconscious after saving Piper from a brick that was about to hit her which was thrown by an angry mob of Romans. Thus, Piper takes care of an unconscious Jason. To pass the time, she looks through her dagger Katoptris despite not wanting to and sees the sign Topeka 32, the Romans preparing an attack against the seven, and the most unsettling image: her, Jason, and Percy all drowning. After Jason wakes up, and Hazel and Leo are back, she goes with Percy and Jason to Topeka 32 in Kansas. They meet Bacchus there who tells them to go see Phorcys because he knows information about Gaea. Afterwards, he disappears.

Immediately after, Gaea tells Piper that she wants her and either Jason or Percy. She tells Piper she must choose between who should die, and if she doesn't, Jason and Percy will have to fight to the death, when an Eidolon begins controlling their bodies. Jason battles Percy with Tempest, while Percy battles with his Pegasus Blackjack. Percy knocks Jason out and is about to kill him. Unable to stop the two from fighting, Piper tells Blackjack to knock Percy out, which he does so. The eidolons are then charmspeaked by Piper and leave. Blackjack carries all three of them back to the Argo II.

After Percy and Jason wake up, the seven have a meeting, discussing Annabeth's quest, what they learned from Bacchus and who possessed Leo, Jason, and Percy. Piper charmspeaks the Eidolons to leave their bodies and never come back. Even though they know now that it wasn't Leo's intent to hurt the Romans, they have no proof to tell them.

After the seven leaves Atlanta, they dock at Charleston Harbor, Hazel, Annabeth, and Piper agree to go find the southern belle ghost Piper saw in her dagger. They find the ghost, who turns out to actually be Aphrodite/Venus. The girls have tea with her and Hazel asks whether she is Aphrodite or Venus (Piper gets embarassed by her mother's antics with the other two girls). Aphrodite tells her she is both because love is universal and that's why she isn't that involved in the ongoing war. Hazel denies that there is any war yet. Aphrodite then explains that when Athena told Annabeth to avenge her, she meant to get her statue, Athena Parthenos.

After getting back on the ship, the Argo II finally sets sail to the Mediterranean Sea and Rome. Once they finally reach there, they see the Pillars of Hercules, and Hercules is guarding it. Piper and Jason decide to go talk to the god. Hercules will allow them to pass only if they steal Achelous' horn to humiliate him since he was unhappy that Hera was sending them on the quest, since he hated Hera and thus wanted their quest to fail.

When the two demigods get to Achelous River, they hear a peaceful hypnotic singing come from Achelous. Achelous figures that they are here to take his other horn, but Achelous explains why Hercules does not deserve it. Despite feeling bad, Jason and Piper still attempt to take the horn, which Achelous retaliates at by trying to drown them. Jason gets pulled under, so Piper tries to bargain with Achelous and tried to charmspeak him. Achelous believed she wanted to become his bride in trade for Jason's life. When he picks her up, she threatens him that he must let Jason go and she proceeds to cut his second horn off. The two demigods escape after Jason electrocutes Achelous .

Upon their return, Hercules allows them to pass through. He also asks for the horn, however Piper does not give it to him, because Hercules does not deserve it. She and Jason manage to fly back to the Argo II after bruising the god when the horn turns into a cornucopia which spouted a pile of food at him. While flying off, Hercules continues to throw food at them, but they nevertheless escape all the attacks and finally get back to the Argo II.

Later on in the journey, Piper is shown tied up and gagged, kidnapped by Chrysaor, who's ship rammed into the Argo II. He tells the seven that he has plans on selling Piper and Hazel to Circe while giving Percy and Annabeth to Gaea. Percy stops Chrysaor from doing this, by scaring Chrysaor's crew of dolphin men, telling them that their captain is Dionysus, who turned them into dolphins in the first place. Frank then shapeshifts into a dolphin, scaring all of the crewmen back onto their boat. Chrysaor, though not scared, is forced to retreat along with his crewmen.

After Annabeth and Percy prepare for Annabeth's quest in Rome and Frank, Hazel, and Leo are off in the city, Piper, Jason, and Coach Hedge are left on the Argo II. Piper plans a picnic for her and Jason using the cornucopia. A birthday cake comes out along with the rest of the food, Jason admits it is his birthday. Percy returns a little later and asks Piper if they can find the giants through Katoptris. She, however, sees the Romans forming an invasion plan, a spiral staircase near the forum, the same place where her, Jason, and Percy are drowning. They set out in search for the staircases.

When the three do find it, Percy volunteers to go first, in case the place is flooded. When he comes back, he says he found a Nymphaeum. Soon afterward, the nymph Hagno and the nine other nymphs who nursed Zeus when he was younger appear and flood the chamber with magic water, which took away Percy's ability to breathe underwater. Piper decides to funnel her, Jason, and Percy's energy into the cornucopia, releasing clean water and age the nymphs back to youth. The nymphs give them their powers and strength back and tell them whereabouts of Ephialtes and Otis.

They arrive at the twin giants' lair where Nico di Angelo is. Piper defends Nico against all the releasing monsters, while Percy and Jason go against the Giants. The Giants released a Hydra, leading to Percy to set a stack of fireworks off, destroying the Hydra, as well as knocking out Piper.

After being nursed back to health and after defeating the giants with the help of Bacchus, Piper and the rest go and search for Annabeth. When they get there, Piper works to grab Athena Parthenos and get it on the Argo II. She manages to do so but fails to help Percy and Annabeth from falling into Tartarus, which she feels bad about. Leo encourages them all that they will find Percy and Annabeth and tells Festus to start the engine towards Greece.

The House of Hades

Piper is at the helm with Coach Hedge. She is tied up and gagged, along with Coach Hedge, when the Kerkopes board the ship, they steal Piper's knife, the Archimedes sphere, Leo's tool belt, and other things. Jason rips her gag off, but on her command, leaves with Leo to get their stuff back.

Piper is talking to Jason and Leo on the deck of the Argo II. She tells them about the vision she has been seeing in Katoptris, and shares her predictions about a line from the Prophecy of Seven: To storm or fire the world must fall. She explains why she thinks Jason is the storm, Leo is fire, and Gaea is the world that must fall. She also says that she thinks that the three of them will be the final strike, as it started with the trio on their first quest to save Hera.

Piper starts to wonder why the weather has been so cold lately, as it is summertime. She soon realizes why, but does so too late. Khione soon shows up with her two brothers Zethes and Cal. She sends Leo to Ogygia and freezes Jason and the rest of the crew below deck, but allows Piper to stay as she has been claimed by Zethes, despite the fact that Khione hates her very deeply for what she did in Quebec. Khione starts to tell Piper about her plans with Gaea, and how the Earth Mother will soon re-create the world as she sees fit. Zethes then mentions the bomb that they had planted that would let out strong winds that would blow the Argo II far off course. Piper, trying to think of an escape plan, is soon reminded of fire and how it is Khione's only known weakness. She then remembers Festus, and knows how he can "blow some serious flames", though she needs to figure out a way to reactivate him since Leo turned him off. Piper then says that she supposedly has a secret, knowing that Khione would demand to know what it is. Piper then places her hand on Festus' neck, and says some things about the dragon, putting all the confidence she has into her words. Festus wakes and torches Zethes and Cal while she charges towards Khione with her knife, and drives it into her chest, causing her to explode. She dives for the bomb that Zethes had told her about, but grabs it right as it explodes. The winds burst out and blow the Argo II all the way to the southern tip of Africa.

After they finish their repairs and Jason flies the Argo II to Greece, they meet up with Leo. They then head to the Necromantium where Leo and Hazel get separated from the rest of the group. Piper, Jason, Nico, and Frank fight off monsters while Jason gives Frank his position as Praetor. They meet up with Hazel and Leo after Annabeth and Percy come out of the doors of death. The seven and Nico fight Clytius before Hecate comes to finish him off. With the temple about to collapse on top of them, Nico and Hazel's shadow travel the group to the surface where they meet up with Reyna and have a picnic about what to do next. The seven decide to go east to mount Olympus to stop Gaea from waking While Nico shadow travels the Athena Parthenos west to Long Island to prevent the civil war. Later on the Argo II Hazel is telling her and Annabeth how to fight with a sword.

The Blood of Olympus

Along with Jason and Annabeth, Piper infiltrates Odysseus's palace with the help of Hazel's magic. Later, Piper volunteers to be one of the four demigods going to subdue Nike. She wants to try to use charmspeak on the goddess; however, Annabeth says that Nike may see Piper as a threat.

Piper had a conversation about Jason with her mother the night before the mission, and Aphrodite had given her a glimpse of the future. Afterward, Frank and Piper scour the port of Pylos to find the poison with no luck. Piper uses her charmspeak on a ghost to get directions to Frank’s relatives, the fellow descendants of Periclymenus. Frank receives a vial of Pylosian Mint from one of them. Piper and Frank return to the ‘‘Argo II’’, where Piper says she saw a vision of her and Annabeth exploring ruins in her knife, Katoptris. The ship lands in Sparta, and the two girls set out to find the chained god's heartbeat. In the shrine of Phobos and Deimos, they face a giant called Mimas, who was born to slay Hephaestus. Piper and Annabeth defeat the giant with emotions, not rationality. Piper summons the makhai, the spirits of battle, and they kill Mimas.

With Leo and Jason, Piper visits Asclepius, the god of medicine. She convinces Asclepius to help them by using her charmspeak, and the god gives them the physician’s cure after a bit of considering.

The Argo II flies to Athens. With the help of the Gemini, she, Annabeth, and Percy go to the Acropolos using an underground route. Using her charmspeak, Piper finds out that King Kekrops (the king of the Gemini) really intended to deceive the demigods and destroy them in the underground tunnels. She successfully convinces him not to go through with the plan, and the three infiltrate the Giant Army disguised as Earthborn, and begin to disable onagers. However, Percy and Annabeth are seen and captured by the giants, while Piper remains undiscovered. Just as Percy and Annabeth are about to be sacrificed, Piper interferes, and the Argo II crew begins attacking the giants. Still, with the full force of the seven demigods, they could not be defeated without the gods and are surrounded.

The gods soon join the battle, but it was a little too late—Gaea was already awake because Percy's nosebleed ended up falling on the ground. However, they successfully defeat the giant army with the assistance of the gods. Piper fights Periboia with her mother’s help. After the battle, Piper questions why the gods need them to finish off Gaea if they are so powerful. Her mother laughs and kisses her, explaining that the gods need demigods as much as demigods need them, as difficult as it is to admit.

The seven demigods return to Camp Half-Blood with Zeus's help. There, they find Gaea awake and the Greek and Roman demigods fighting a horde of monsters. Leo snatches Gaea’s body into the air with Festus, and Piper and Jason join him. Piper uses her charmspeak on Gaea, trying to get her to sleep. Leo then blows up Gaea with help of Octavian's onager blast, and everyone assumes he was killed from the blast. Piper was devastated that she could not save him.

Piper, along with Annabeth and Reyna become inseparable following the battle as they work together to smooth friction between the two camps. Before the legion leaves back to Camp Jupiter, Piper asks Reyna what she was told in Charleston two years before by Aphrodite. Reyna tells Piper that Aphrodite was told her that she would end up being alone. Piper curses her mother and tells Reyna that she does not need a boyfriend. That night after the legion leaves Jason takes Piper to the top of Cabin One where there is a secret passage to the roof. While on the roof they kiss passionately.

Percy Jackson's Greek Heroes

Right after finishing his narration of this book, Percy reveals that after the events of The Blood of Olympus, he, Piper, and the rest of the Seven started the tradition of monthly Argo II reunion parties, and he is quite worried about being late to the current one.

Between the Series

Several days after the death of Gaea and Leo's death and resurrection, a parchment scroll with a holographic message, sent from the resurrected Leo, came fluttering into Camp Half-Blood on the wind. Piper and Jason while angry at Leo for his long absence, are extremely relieved to learn that he is alive, and both of them spend most of September searching for Leo, Festus, and Calypso.

Eventually, however, Chiron persuades them to resume their school year, and so Piper and Jason depart to a school in Los Angeles (where her father Tristan McLean now lives), taking Gleeson Hedge, Mellie, and Chuck along with them.

They eventually learn that there is a mythological force behind the wold fires and explore the Labyrinth. Jason runs into Herophile who tells him that if he and Piper pursue Caligula, one of them will die. He does not tell her and ends the quest and they return home.

Sometime later Piper breaks up with Jason due to feeling that their relationship was forced onto them by Hera and her mother and wanting to live for herself.

The Trials of Apollo

The Hidden Oracle

Piper is not present at Camp Half-Blood when the human Apollo and Meg McCaffrey arrive, so Nico di Angelo explains where she and the rest of the Seven are now while showing Leo's holographic message. In the story, it is noted that Jason and Piper are together in Los Angeles, studying after an unsuccessful search for Leo.

The Dark Prophecy

Leo mentions Piper when commenting on Emmie's tofu enchiladas. Lityerses mentioned her when confronting Apollo and Calypso at the Indianapolis Zoo.

The Burning Maze

To see this text, hit the "Expand" link to the right.

The Triumvirate Holdings, specifically Caligula, has filed many legal papers against Tristan McLean and has caused Piper's family to lose almost everything except their house in Tahlequah, Oklahoma. She and Jason went to explore the Labyrinth and became separated. They met up again and he would not tell her what he found. The two eventually broke up.

As movers are emptying their house, she is visited by Apollo, Meg McCaffrey, and Grover Underwood and they talk outback. She tells them how her father has lost everything due to Triumvirate Holdings and will be on Oklahoma by the end of the week. She agrees to join them in finding the Oracle of Erythaea. She gets her weapons and leaves with the others to enter the Labyrinth. She borrows a car from Mr. Bedrossian, her neighbor, and they head to downtown Los Angeles. She leads them to the entrance and shoots the guard with a poison dart. After the poison takes effect she leads everyone to a service elevator and into the labyrinth. They wander around and run into two of Grover’s scouts, Meg and Grover they to heal them but feel it would be easier on the surface. She, Meg and Apollo continue on and find an abandoned parking garage where they run into Medea. They two exchange a brief Wars of wards and she warns her companions they are being persuaded by her. The sorceress unleashes her dragons on them. She and Meg take out the dragons, however, Medea traps the others and teases Piper with what Jason was told by the oracle. Piper baits her into a fight and she chooses her blow dart tube as her weapon while Medea chooses Helios. The fight moves quickly with the daughter of Aphrodite receiving severe burns that she could die from hours later. Apollo tells her to shoot Medea with a blow dart and she hits her shoulder. Helios states to intensify his heat and the three flee.

They make it to the surface and pass out. They are taken back to Aeithales for better healing. They agree to ask Jason what the oracle told him and to steal Caligula’s boots of guidance. In the morning she drives Meg and Apollo to Jason’s school in Pasadena. She leads them to his class and they head to the son of Jupiter’s dorm room to talk. He tells them what the oracle told him, but she knows he is holding back. She and Meg go to the office to get out of school while Apollo helps him pack.

She borrows a school van after their borrowed car was towed. They drive to Santa Barbara and search Stearns Wharf. During dinner they see a fleet of yachts form a blockade around the harbor with mortal military and law enforcement helping with security. They agree to search the center ship. She talks some mercenaries out of a dingy and they take it. When they reach the center of the blockade Jason flies her up first. The two are quickly captured and, with Meg and Apollo, are taken to an interrogation room to hear their story. All no the way she sees a painting from her house. After Meg tricks the Pandai into revealing the locations of the boots and Caligula, the daughter of Demeter attacks. She and the others take out all but Crest and separate with her and Apollo going after the shoes while Meg and Jason go after Caligula. Apollo dresses her head would and they head out. They go a few boats without being noticed and when they are she sings with Apollo playing the ukelele. They stop in Caligula’s wardrobe boat and rest in a dressing room. Piper tells Apollo that even though she likes Jason, she feels their relationship was forced into them by Hera and continued due to her mother. She also feels that she is not Cherokee due to the tribe’s matrilineal views of descent. She says she wants to define herself by herself and Apollo agrees to that. She wants to know what she wants without people pressuring them. They make it to the shoe boat and get the location from the guards. They find the room and the shoes, the same sandals that gave Caligula his nickname. They are found and told by Crest that Meg and Jason have been captured. Before they can move she and the Pandos are knocked out by Incitatus and taken to Caligula with a wounded Apollo. She is slung over the horse’s back and taken to Caligula. She is awakened by Caligula in his throne room and held in a standing position. She collapses on the floor again and watches Apollo stab himself. She punches Medea and helps Apollo up. They watch in despair as the emperor kill Jason and flee on Tempest.

They arrive at her house. She refuses help from Apollo but accepts ambrosia from Meg. After Tempest brings Jason to them, they suggest ways to heal the deceased son of Jupiter to no avail. Her father arrives and tells the others to use the landline to call an ambulance. She angrily tells Apollo to leave, blaming the former God for having involved her and Jason in the quest, which caused Jason's death.

Just as Medea is about to kill Apollo, she arrives with the Meliai and stabs Medea in the back before pushing her into the flames of Helios. She tells them she received a message from a cloud nymph and hunt to the labyrinth entrance and, with the help of the elder dryads, took out the security and found the room they were in. She notices the prophecy on the floor after Meg points out the message, tells Apollo he needs the help of Reyna. They exit the maze and are surrounded by Incitatus and a dozen Pandai. She is stopped from attacking by Herophile. There would be executioners are killed by the Meliai, she goes back to Malibu.

The next day Piper meets up with Apollo and Meg at an airfield in Santa Monica Beach and gives them the plane to take themselves to Camp Jupiter while her family and the Hedges drive to Oklahoma. When Leo arrives she tells him about Jason and he tells her about Camp Jupiter. He insists on taking Piper to Oklahoma on Festus as it is on the way back to Indianapolis.

The Tyrant's Tomb

Piper is mentioned when Hazel LevesqueLavinia Asimov, and Don Meet with Apollo and Meg McCaffrey. When Apollo, Meg, Don, and Lavinia enter the Caldecott Tunnel, carrying Jason Grace's burial shroud, they run into Hazel. Hazel demands who is in the casket, but she can tell that from Apollo's expression that it wasn't good. When she realizes, she starts to sob, and says that she had dreams about Caligula's boat. Hazel continues to cry and asks "Why did you do this? This isn't fair to Piper."

The Tower of Nero

Piper is visited by Apollo back in his godly form in Oklahoma, kissing a girl called Shel. She then talks with Apollo, and explains that she and her father are adjusting well to Oklahoma and the daughter of Aphrodite congratulates him before she returns to Shel.

Personality

Piper McLean is a calm, but rebellious spirit who is always loyal and protective of her friends and isn't afraid to stand up for them. Piper has always followed her heart, which does her well in The Blood of Olympus. Piper is also a leader, as she is the counselor of Aphrodite cabin. Her disagreement with the rite of passage and Drew's tortures on her siblings show that, unlike most of Aphrodite kids, she doesn't care about looks as much as the personality and shows children of Aphrodite aren't cowards and gossip-aholics like a lot of people from the other cabins think. She stands for her beliefs and fights to right the wrongs in her cabin.

Piper was very caring and loving towards her ex-boyfriend Jason and is frightened, sad and angry at anything that may pose a threat to her bond with him, such as when Drew claims that Piper needs to break his heart as an initiation into the cabin. She was greatly saddened by the possibility that her first relationship with Jason was a Mist-induced illusion and breaks down in tears when Annabeth asks her what Jason's last name is (which she doesn't know). She also likes to touch Jason in very kind and loving ways such as holding his hand, leaning against his chest, resting her head on his leg, wrapping her arms around him and having his arms around her, probably since they were together in her Mist-manipulated memories. These memories are much sharper to Piper because she is a daughter of Aphrodite, so she can sense possibilities. She also seems to have a soft spot for her friend Leo Valdez.

Compared to the other children of Aphrodite, Piper is much more aggressive and down to earth and is also somewhat tomboyish, not constantly focused on herself or her looks. She has a funny sense of humor, and laid-back most of the time. When claimed by Aphrodite, she complains that she can't get rid of her makeup or her new hairstyle and finds it to be annoying, to say the least. Before she was claimed by Aphrodite, Piper expressed that she wanted to be the daughter of Athena, Hecate, Artemis (before realizing she was a maiden goddess), or any goddess that wasn't Aphrodite, and she also thought Aphrodite cabin had been a "life-sized dollhouse" where supermodels went to die, and when she was claimed, she didn't fit in at all, and still doesn't. Rachel, the Oracle of Delphi, thinks even Annabeth wants Piper to be a child of Athena. Aphrodite herself also said that she was much smarter than most of her other children. Piper hates make-up, skirts, magazines, dresses, and popular girls. She said that if she started craving for fashion magazines, she would complain to her mother. She also has no care of her looks at all.

Piper also does not like it when Drew bullies the other Aphrodite children. She feels that Drew is running her cabin like a dictatorship and she doesn't truly understand what love is. Piper is not afraid to stand up to Drew, and because they can both use the charmspeak ability, Drew cannot control her as she does with the other campers. After Piper returns from her quest, she challenges Drew for her position as cabin leader because Drew has never been on a quest and thus, Piper is able to take the leadership role. At the end of The Blood of Olympus, Drew seems to not mind Piper's position of leadership as she can spend more time gossiping and doing in-cabin makeovers.

She appears to be more perceptive of others' feelings compared to the rest of the members of the Argo II. Out of the seven demigods, Piper is the most compassionate and understanding one.

Like everybody on the Argo II, she had an insecurity with her own identity. As seen in The House of Hades, hers appeared to be that she felt useless and not a hero at all without her friends. This was exploited by Khione as she attacked the ship. Though those thoughts have likely stopped after she found confidence during that same confrontation.

Appearance

In The Lost Hero, Piper was first described by Jason to be a very beautiful girl of Native American (Cherokee) descent, with chocolate-brown hair that was cut choppy and unevenly, and had thin strands braided down on the sides. Her eyes seemed to change color like a kaleidoscope, going from brown to blue to green, and she was dressed in a fleece snowboarding jacket, faded jeans, and hiking boots. Though she wore no makeup, and she had facial imperfections (such as pimples, namely one at the base of her nose, which had been there for some time), she was still so beautiful that she drew attention even when trying not to.

After Piper was claimed and subsequently blessed by Aphrodite, she temporarily became the most gorgeous girl in Camp Half-Blood--her hair turned lush and long, braided with gold ribbons down one side so it fell across her shoulder, and she wore perfect makeup that made her lips cherry-red and brought out all the different colors in her eyes. Her skin also became perfect, she was adorned in a beautiful, sleeveless, ankle-length white gown with an embarrassingly low V-neck, and her biceps were circled by delicate gold armbands, while an intricate necklace of amber, coral, and gold flowers glittered on her chest. Her pimple also disappeared too. However, Piper still preferred her old look. Jason Grace even exclaimed that she was "beautiful" and "a knockout" in front of the whole camp, and though Aphrodite's blessing faded later on, he thought that she looked more beautiful without makeup and her hair back in its old choppy style, and it seemed that her facial imperfections had still permanently vanished.

In The Blood of Olympus, when Piper used her charmspeak to its full potential, Leo observed that her smile was "so warm it would've melted the Boreads".

In The Burning Maze, Apollo describes Piper to have a "finely chiseled nose", "perfect complexion", and a "softly curved physique."

In the end of The Burning Maze, Piper cuts off her hair into an very short and choppy style that reminds Apollo of Thalia Grace. 

However, despite her stunning beauty and her parentage, Piper is described as having a relatively simple, tomboyish style most of the time.

Abilities

As one of the seven, Piper is definitely an extremely powerful demigod whose powers develop rapidly throughout the series.

  • ADHD: Like most demigods, Piper possesses inborn supernatural battle reflexes and senses that she uses to analyze the fighting style of her opponent.
  • Dyslexia: Piper's brain is hard-wired for reading Ancient Greek instead of modern languages.
  • Fighting Skills: As shown in The Lost Hero, despite her lack of any real training, Piper was already a decent knife-fighter, being able to defeat dozens of monsters though she charmspoke them first, and in The House of Hades, she started to learn how to fight with a sword under Hazel and started improving rapidly. By The Blood of Olympus, Piper's skills had improved to the point that she single-handedly defeated an entire flock of "demon chicken ladies" while on guard duty, which implies that she is a prodigious swordswoman. During the final battle with the Giants, Piper also held her own against the Giantess, Periboia, in an intense fencing duel, and ultimately defeated her with Aphrodite's help.
  • Knowledge of Greek Mythology: As seen in The Lost Hero, through her previous research on the subject for a movie role her father played, Piper had an extensive knowledge of Greek mythology allowing her to know ways to defeat different ancient Greek characters.
  • Singing: While Piper's father had always told her that she had a good singing voice, she was too self-conscious and shy about ever singing in front of anyone, not even participating in campfire sing-alongs. However, when Piper finally did sing in front of her friends and Kekrops in The Blood of Olympus, her words "filled the mess hall", greatly impressing Jason and Leo Valdez. Piper could also weave Charmspeak into her singing.
  • Superhuman Strength: As a demigod, Piper possessed physical strength greater than an average human's - she easily threw a fifty-pound shield at Medea, making the latter topple on a table full of potions.
  • Superhuman Agility: As a demigod, Piper is more agile than the average mortal - she was able to weave herself through a thick group of Giants to haul herself up to Achelous' neck.
  • Superhuman Durability: As a demigod, Piper is more durable than a regular human being, as shown by how she only suffered a broken ankle when she fell dozens of feet from the sky.
  • Superhuman Reflexes: As a demigod, Piper's reflexes are greater than the average mortal, as shown by her being able to dodge an axe thrown by the Giant, Mimas, even when she did not see it.
  • Willpower: As shown in The Lost Hero, Piper possessed tremendous willpower that enabled her to effectively resist charmspeak from both Drew and Medea who were both powerful charmspeakers.

Aphrodite, her mother.

  • Amokinesis: As a daughter of Aphrodite, Piper has a level of control over the emotions of love, lust, etc., but on a much smaller scale than her mother. As seen in The House of Hades, she was able to use the power of love to melt Khione's ice and permanently start up Festus.
  • Emotional Insight: As a daughter of Aphrodite, Piper is extremely good at reading people's emotions. In The Lost Hero, even without really knowing how she did it, she was able to translate the expressions on Annabeth's and Chiron's faces into a real conversation by just reading them even though she didn't know them very well yet.
  • Charmspeak: Piper has the power of charmspeak, which allowed her to influence others with enhanced vocal persuasiveness. At first, this ability was described to be unreliable and tiring but after the encounter with Khione in The House of Hades, this ability gradually became increasingly powerful as the series progressed, to the extent where it could even affect certain deities even though some others were completely resistant to her charmspeak. As of the The House of Hades, Piper's skills in charmspeaking had evolved to the point where she was even able to awaken Festus after finally understanding her abilities. In The Blood of Olympus, she used her charmspeak to make a fully-powered Gaea herself fall back to her slumber, though she stated that it would not have lasted long.
  • Beauty: Regardless of how she looked and what she wore, Piper was able to radiate beauty, which sometimes prevented enemies from willingly attacking her even as she charged them head-on. She could also attract the opposite sex when she walked by, and she might have the ability to change her physical features - Jason once mentioned that her eyes "constantly change color, like a kaleidoscope going from brown to blue to green."
  • French fluency: As a child of Aphrodite, Piper is noted in The Lost Hero to be able to speak French fluently due to it being the "language of love."

Weapons/Items

  • Katoptris: Piper is the wielder of an Ancient Greek ceremonial dagger called Katoptris. It was given to Helen of Troy as a wedding gift from Menelaus, Helen's first husband. The dagger seems to show a scene of something that has importance to whoever looks at their reflection in the blade (for example it showed her dad captured by giants in The Lost Hero). Katoptris is a Greek word meaning "looking glass." In The Blood of Olympus, after Gaea and the Giants' defeat, the dagger's visions have stopped completely.
  • Cornucopia: In The Mark of Athena, Piper receives the Horn of Plenty after cutting off the horn of the River god Achelous. It allows her to summon food and water if she has enough will and concentration. It powers also seem to increase if multiple people focus at the same time. In The Blood of Olympus, her Horn is sacrificed to Deimos and Phobos, the twin gods of fear and terror.
  • Sword: In The House of Hades, Piper also picks up Zethes's sword after he was defeated, and Hazel starts to teach her how to use it. But it was lost in The Blood of Olympus.
  • Blowgun: During their journey for The Oracle of Erythaea, Piper uses a blowgun given to her by her grandfather. It was destroyed during her fight with Medea.

Relationships

Love Interests

Jason Grace, her ex-boyfriend.

Jason and Piper actually met in The Lost Hero, but Piper had fake Mist memories of the son of Jupiter. In her memories, she spent three months for Jason to notice her, then they finally kissed on the roof of the Wilderness School. The next three weeks of dating were the best in Piper's life, but in reality, the memories were fake. Jason woke up on a bus on the way to the Grand Canyon with no memories, and Piper squeezed his hand and asked if he was okay. Jason thought that Piper was cute and seriously beautiful, but he didn't know her. Piper eventually realized that Jason wasn't lying when he said he didn't know who she was, and tried to take his hand again, but he let it go. However, even though Jason didn't know Piper well, he was angry when Dylan and the mean girls harassed her, and saved her from venti, holding on to her waist. As for Piper, she loved Jason and thought his face was kind and gentle, but always a little sad. When they arrived at Camp Half-Blood, Piper found out from Annabeth Chase that her memories of Jason were fake, and she cried, heartbroken. Piper still had feelings for him and was jealous when he talked to Annabeth, and hated when Drew Tanaka hit on him. Jason was very attracted to Piper when she was blessed by Aphrodite, and called her a knockout. He wanted to wrap his arms around her but restrained himself, not wanting her to think he was shallow.

Jason and Piper both went on the Quest for Hera, along with Leo Valdez. Jason was glad she was found with him, and knew he would need help, and it felt right for Piper to be with him. But his feelings for her were complicated, because he didn't know how much he liked her or why, and felt like he had messed with her head enough. Piper got slightly jealous when she saw him looking at a picture of a girl, and thought it was his girlfriend (it was actually his sister, Thalia Grace. The two bonded over the course of the quest. When they visited Boreas' palace, Jason took Piper's hand for reassurance, and she touched his arm when he zoned out. Jason was grateful for Piper and needed a friend, and thought he was more beautiful after she lost the Aphrodite blessing. He thought she was beautiful and confident. He even began wishing their fake relationship was real the longer he spent with her, but thought it wasn't fair to Piper, in case he had someone waiting for him back home. Jason told Piper she was amazing after they left the palace, but Piper felt guilty, thinking if he knew the truth about her, he wouldn't like her anymore. She also became skeptical of Jason, worrying if he was the enemy.

The two liked to speak in private a lot, which made Leo Valdez jealous and like a third wheel. They saved each other's lives a lot on the quest, with Piper saving him from Medea and Khione, and Jason saving her from Midas and Lityerses, and from hypothermia. Jason ended up apologizing to Piper for the fake memories and messing with her head, and Piper reassured him that no one asked for this and it wasn't his fault. After that, Jason encouraged Piper to get some sleep and she put her head in his lap and started snoring. Jason encouraged her to tell him and Leo about her father when he found out he was in trouble, but Piper didn't want to, afraid it would hurt them. Piper eventually told Jason and Leo, and to her surprise, Jason put his arm around her and apologized for what happened to her dad, and said he trusted her with his life. After she saved him and he had to go home, his memories of the incident erased, Piper sobbed into Jason's shirt and he hugged her, and he said she did amazing.

After the quest was over, Piper threatened Drew that if she even talked to Jason, she would throw her over the Long Island sound, and that Jason was hers. Piper could also sense that Jason saw his past, and she didn't push him to talk about it, and told him she would follow him anywhere. The two held hands afterwords. People watched Piper and Jason and were disappointed that they didn't kiss, but Piper knew that they would in time. As for Jason, he had feelings for Piper, but when he remembered Reyna, her memory made him question how he felt about Piper, and made him wonder if he was doing something wrong.

In The Demigod Diaries, they were officially in a relationship. Piper became very mad and tried not to scream when Maenad's giggled and touched Jason's shoulders. Piper leaned over and kissed Jason before she and Leo went to distract the Maenads.

In The Mark of Athena, Piper and Jason deeply loved each other, and Jason wanted to show her around New Rome, to Reyna's chagrin. Jason defended Piper from the Romans when they were getting pelted with stones and plates, getting hit with a brick in the process. Piper kept an eye on Jason once they were back on the Argo II recovering. Piper gave him Nectar and Ambrosia, and was worried that when he woke up, he wouldn't remember her. Piper was very relieved when he woke up, and almost sobbed when he said he remembered her as his awesome girlfriend. However, Piper was jealous of Reyna and felt guilty about being Jason's boyfriend after she met her for the first time, and was worried that Jason had feelings for her. The jealousy was made worse when Jason encouraged Piper to tell Reyna the truth about what happened, and Hazel and Annabeth winced, wondering how he could be so clueless. She also wished he wouldn't act so distant sometimes, like when he was reluctant to tell her about the Mark of Athena and when he thought about his old life at Camp Jupiter. After she saved him from Eidolons, they talked against the rail, and he put his hand on her waist, and discussed the Mark of Athena. Jason reassured Piper that he didn't have feelings for Reyna and apologized for telling her to contact her, and said he would never go back to Camp Jupiter unless she came with him.

Their relationship was more stable after that, though Piper was still jealous of Reyna and when Jason talked about when he and Reyna went to Charleston, he nervously glanced at Piper. She also got jealous when he said he trusted her, but Jason said that he was beautiful and powerful and didn't want her to be Roman, he wanted her to be herself, but she couldn't get rid of her doubts. Piper mostly admired how he was a leader and how he didn't break rules, and admired how easily he did each task. The two cooperated well when they defeated Achelous and Hercules, and he saved Piper by grabbing her waist and flying. When they arrived in Rome, they had a picnic and Piper was excited when she found out it was his birthday. Jason confided in Piper that he was always the leader at Camp Jupiter and was not used to being in a crew of equals, where no one was really the leader. Piper reassured him that they would figure it out, and even though he wasn't sure if he bought what she said, she was glad he was confiding in him. They kissed after. Later, when they went to save Nico di Angelo and they almost drowned, Piper mouthed that she loved him. She later reassured him that it wasn't his fault Percy and Annabeth fell into Tartarus.

In The House of Hades, the two were close as ever and Jason couldn't bear the fact of not returning to Camp Half-Blood with Piper and Leo. Piper's jealousy of Reyna seemed to have subsided, though Jason was still cautious when he mentioned her. Every time Jason thought of Reyna, he could only think of Piper, and wondered if she was using Aphrodite magic on him. Jason was relieved when Piper suggested going to Dalmatia with Nico and him, but Nico said she shouldn't go, disappointing Jason. After Croatia, Piper could sense something big happened there, but she didn't push him to tell her. She was also confused when he defended Nico, and she and Leo quizzically glanced at each other, wondering since when he defended Nico. Piper noticed how Jason had changed in the last few months and had realized he was getting more comfortable with himself. Jason excitedly kissed Piper when she figured out the last line in the prophecy, and said she was a genius. Jason was very grateful for Piper after she saved him from Khione, but he was worried she was being too hard on herself after she was afraid to let her guard down. They both agreed they were lucky to have each other.

In The Blood of Olympus, they both went to Ithaca with Annabeth, and he was proud for her when she defeated a flock of Harpies the day before. Piper caught him after he was stabbed by Michael Varus and she acted calm, healing him so he wouldn't die. Piper kissed him on the forehead and comforted him so he could stay conscious, and made sure he stayed with him. She reassured him that Nico would be okay and had him think about the s'mores fight at camp half blood and his birthday in Rome. Piper helped him heal over the following days and regularly changed his bandages. She also told him Cherokee stories to comfort him. Jason also thanked Piper for keeping him from slipping away and confided that he was worried he would turn out like his mother. Jason was also glad that Piper was no longer jealous of Reyna, asking about her well being. Jason also reassured Piper that she was the best person to hold the Physician's Cure. They both helped defeat Gaea together. When they returned to Camp half blood, Piper and Jason went on the roof and they snuggled. They kissed, and Jason said they were making their own story and making a fresh start, and that was their new first kiss. They then confessed their love to each other. They mourned over Leo the entire night and told stories about him, hoping he was alive.

However, their relationship didn't last long after that. In September, they spent the entire month looking for Leo, then they went to school together in California. Piper later broke up with Jason. Even though she still loved him as a friend, she realized that Hera forced them together and their first months of dating were an illusion, then Aphrodite pushed her into thinking she needed to be with someone romantically. She wondered what her life would be like without all that pressure, and was figuring herself out and trying to find herself. He transferred to an all boys school after they broke up, so Jason could be away from drama. Jason was confused as to why she broke up with him, and Gleeson Hedge and Mellie became mad at Jason as a result, due to not knowing why they broke up, thinking he dumped Piper. Months later, they both went through the Labyrinth to figure Herophile's location, but Jason found out something he wouldn't tell her, which was revealed to be that one of them would die.

In The Burning Maze, Apollo was confused when she found out they broke up, but Piper said that not all relationships last forever like Percy and Annabeth. Jason and Piper were still friends, but were very awkward around each other. When she said hi, she had a hint of strain in her voice. Piper also told Apollo that Jason had done a lot of designs for temples of the gods and that he could see his sketchbook, making Jason frown, wondering if he was praising or criticizing him. Jason finally admitted to Piper that he hadn't told her everything in the burning maze, and tried to apologize, but Piper pushed for information. Piper was angry when he didn't want to tell her, and said after all of the dangers they have faced, she was mad that he was lying to her, just to protect her from Caligula. Jason admitted that he messed up by not yelling her, but he didn't, due to how things have been between them. Piper told him that it wasn't about them, it was about that Satyr's and Dryad's were dying. Jason later confessed to Apollo that the reason he didn't tell her everything was because he knew she wanted to spend time with her dad and was excited to return to Oklahoma, and that he planned to let her go and face Caligula himself. Jason told Piper the truth later, and Piper said he would have done the same thing if she were him. She said she was furious, but also empathetic. Apollo was surprised how well they understood each other and could talk about difficult subjects. When they made it to the Julia Drusilla Yachts, Piper grabbed onto Jason's waist and let him fit her up, despite them being broken up. She later told Apollo that Jason was her closest friend, even more than Annabeth.

Jason later sacrificed himself and died to save Piper. Piper tried to warn him about Caligula and tell him to leave with her, but he was killed by Caligula to make sure she wouldn't die. Piper was devastated when Jason died, and was in a panic: yelling at Apollo, throwing sand, slapping away the ambrosia and nectar Apollo tried to give her, and shuddering with dry sobs. Piper refused to believe he was dead, and said Jason had gone through too much to die. When Tempest brought Jason's body to the beach, she begged Apollo to fix him, and shook his dead body, yelling his name. She mentioned a Cherokee legend that said that a plant could cure him, and mentioned that he could go through the Doors of Death, since Medea came back that way. Apollo told her she couldn't, and Piper became furious, saying that he didn't care, and was angry that he died for a pair of shoes just for Apollo to see an Oracle. She told her father he died in a surfing accident while sobbing, and told Apollo to never come back, blaming him for his death. Piper later avenged his death by defeating Medea, telling her that while Jason is in Elysium, she wouldn't.

Piper made sure that Apollo and Meg McCaffrey. She also arranged Jason's final arrangements. When Piper reunited with Leo and he asked where Jason was, she broke down and hugged him and cried, and told him what happened. Piper was sad that it happened so fast and she never got to say a formal goodbye to Jason. In The Tower of Nero, she was glad that Apollo was buried at Camp Jupiter, and said Apollo did right by him. She said that the memory of Jason's death was part of her now, and that she would never forget.

Shel is Piper's girlfriend who she met after moving to Oklahoma. They are seen to together on the roof of her house, holding hands and kissing each other on the lips.

Rivals

Reyna Ramírez-Arellano, her former rival and good friend.

Reyna and Piper first met in The Mark of Athena at Camp Jupiter, when Piper came with Leo, Jason, and Annabeth from the Argo II. Piper practiced lines to say to Reyna when she met her, but ended up not having to say them since Reyna welcomed her and her friends, and since Jason introduced Piper to Reyna. However, Reyna quickly grew jealous of Piper as she looked between Piper and Jason with her brow creased, realizing they were a couple, and her eyes became stormy. Reyna became even more jealous when Jason asked to walk around New Rome with Piper, like rubbing salt in a wound, though she let them. While talking to Annabeth, Reyna revealed that she didn't trust what Piper said due to the sorcery in her voice. Reyna then thought that Piper and her friends betrayed her for firing on Camp Jupiter, making matters worse.

As for Piper, she was prepared to hate Reyna, but admired the way she kept her feelings in check, staying polite and in control after realizing she was dating Jason. Piper didn't blame Reyna for having a crush on Jason, and knew why she would. She respected her for giving the Greeks a fair chance and putting the needs of her Camp ahead of her emotions, and thought she wasn't so bad. Reyna even made Piper feel guilty about dating Jason, which was silly to Piper since Reyna never dated Jason. But Piper never wanted to befriend her and the Romans in the first place, since she was afraid Jason would leave her for Reyna and Camp Jupiter. Seeing Reyna made Piper's worries about Jason leaving her worse. Piper's jealousy became even worse after Jason suggested that Piper contact her to convince her that they were innocent, oblivious to her jealousy, making Piper feel like all the blood in her body was draining to her feet. Piper said she could try, but she knew Reyna wouldn't be able to stop Octavian. Piper lamented to Jason how Reyna was powerful, beautiful, and Roman, and was jealous of how he trusted her, but Jason reassured her she didn't want her to be Reyna, she wanted her to be herself.

By The House of Hades, Piper was no longer resentful or jealous of Reyna and when she heard she was coming to meet them, Piper gave Jason a teasing smile and said she would love to see Reyna again, but she was unsure if she could find their location. When Piper saw Reyna again, she told her that Frank was amazing in the House of Hades, encouraging her to promote him to Praetor. Piper was also the one to tell Reyna that Octavian was gathering forces to attack Camp Half-Blood.

In The Blood of Olympus, Piper asked Zeus if Reyna was okay, which shocked Jason, but he was happy about it. After Piper arrived at Camp, Reyna seemed to have been over her jealousy also and said it was about time she came, and Piper grinned, saying she had some giants to kill. Reyna returned the smile and told her to help herself to some barbarians, and Piper thanked her, making them jump into battle side by side. After that incident, Piper and Reyna, along with Annabeth, became inseparable as they helped the two Camps get along, wandering around Camp to check on the repairs, and Reyna valued Piper as a go-between between conflicts. At the campfire one night, Piper teased Reyna and asked if she was sure if her mother was a war goddess, and Reyna said she still intended to fight battles, but now they fight together.

The day Reyna left, Reyna and Piper had one last conversation at the dock. Piper thought that Reyna was the only demigod who hadn't changed much during their journey, and knew she had been through a lot of pain. She wondered how she could bear it all and wondered if she had anything to confide in. Piper also thought she had a regal and beautiful face. Piper told Reyna that she did so much for both camps and wished she got more credit, and that without her, nothing they did would have been possible. Reyna laughed and thanked Piper, but said she didn't want attention, and that she knew what that was like. Piper understood that she didn't want to attract attention, after being a daughter of a movie star. Piper also told her she could sense that she could lend strength to others. Reyna was skeptical and wondered if Nico told her, but Piper said it was because she can sense it and see how much it drains her. After Piper asked her how she gets her strength back, Reyna joked that when she does, she will let her know, but Piper could sense sadness behind the words. Piper offered that if she needed time to take a break or get away, she can come to Camp Half-Blood and it would be good for her to take time for herself. Piper also joked that they would have to ban her from capture the flag because she could beat the entire camp solo. Reyna thanked Piper and said she would consider the offer.

Before Reyna left, she asked Piper to explain something that Venus told her, since she was her daughter. Reyna told her what Venus told her in Charleston, and her words broke as she said how much she struggled with that. Piper became mad at her mother since she keeps ruining lives. Piper then tells her that she didn't know what she meant, but she knows that Reyna is an incredible person and that there is someone out there for her, and maybe it’s not a demigod or it is a mortal. Piper said that until then she has friends, and that even though she gives strength from others, she needs to draw from it once and awhile, and she is here for her. Reyna said that she had a way with words, and Piper promised she wasn't charmspeaking. Reyna said no charmspeaking was required and held out her hand to shake it. They shook hands and Reyna said she has a feeling she would see her again, and a Piper knew, because she was her friend and family now. That night, Piper thought the camp was empty without her and the Romans.

Drew Tanaka, her half-sister and former councilor.

Drew and Piper dislike each other from the get-go, because they both liked Jason. Drew flirted with Jason constantly during The Lost Hero, making Piper jealous (However, it is eventually clear that Jason prefers Piper). Piper also disliked Drew as head of the Aphrodite's Cabin, for being cruel and unkind to Piper and her cabinmates, and for supporting things that were unkind. Drew, on her part, is unimpressed and harshly critical of Piper's tomboyish style, and is horrified after Aphrodite claims the latter shortly thereafter. At the end of The Lost Hero, Piper challenges Drew to a fight to become head of the Aphrodite cabin. Out of fear, Drew steps down anyway.

By The Blood of Olympus, however, Drew seems to not mind Piper's position of leadership, as she can spend more time gossiping and doing in-cabin makeovers as a result.

Friends

Leo Valdez, one of her best friends.

Piper and Leo had known each other for a long time, for about a few months before the events of The Lost Hero. The two had trusted each other enough for Piper to tell Leo that her father, Tristan McLean, was a famous movie star, and Leo understood that Piper wanted to fight her own battles. Piper also knew that Leo ran away six times. However, when Leo got fake Mist memories of Piper and Jason, Leo felt like a third wheel to Piper and Jason when they were a couple. He was happy for them, but it made him feel like they didn't need them anymore. However, they were still friendly and Leo teased Piper about her stealing a BMW. Leo also winked and shot her a finger fun at the campfire. As for Piper, she thought a Leo was annoying, like when they were on the way to Camp Half-Blood, and thought he was hyperactive and made stupid jokes. Piper also thought that Leo was very ADHD. Unlike the other kids at Camp, Leo didn't make a big deal when Piper was blessed by Aphrodite, and thought it was amazing but didn't really care. Leo ended up repairing Festus so he, Piper, and Jason could go on the quest. Piper was shocked when she saw Leo with Festus, but said it was beautiful and was impressed by the machinery.

On the quest, Piper and Leo bonded. Piper saved Leo's life numerous times, like from Medea. Leo trusted Piper enough to tell her about Tía Callida, who was actually Hera, which he never told anyone before. He was also grateful when Piper and Jason weren't going to leave him alone with Calais, and willing to fight for him. Leo also reassured Piper that it wasn't her fault when Festus fell. However, Leo was slightly jealous of the two. He was excited when the mist memories were fake because he felt like it was a chance to reset their dynamic. But since Piper and Jason were heading to be a couple again, he thought they didn't want Leo around and he was worried being an odd man out again. He also felt like a reject when Piper and Jason got to see Boreas when he didn't. He was also worried she would think he was a freak when she found out he had fire powers. He ended up saving their lives from Ma Gasket and the Cyclops. Piper was very grateful when he saved her life and asked if he was okay, and Leo apologized for not telling her about the fire. But Piper grinned and punched his arm, saying it was amazing. Piper comforted Jason when Festus died. Leo also comforted Piper when he learned about her dad, and assured her that he will help her. Leo comforted Piper again when her father went home, giving her Kleenex, and Piper thought how much he meant to her.

Leo and Piper later had a heartfelt conversation, with Leo comforting Piper about her dad. He reassured her that he will be fine with Coach Hedge protecting him. Leo was secretly struck by how much Piper had changed and seemed more present in the moment. He thought about how she spent her entire semester at the wilderness School trying not to be seen, and now she was impossible to miss. Piper confided in Leo about how she was worried about Jason, and that he may be the enemy. Leo was worried too, but reassured her that he wouldn't betray them after all they had been through, and said they were a team. Leo also realized that Piper was scared of losing Jason after losing her father, and couldn't imagine how it was for her to see her dad break down. Leo reassured her that she was the strongest, most powerful beauty queen he ever met, and she could trust herself and him. Piper was impressed later when Leo showed her and Jason Bunker 9.

In The Demigod Files, Piper and Leo were best friends. Piper helped Leo when he was stressed and when the Argo II almost exploded due to a malfunction, though she was confused at first. Leo thought that Piper's Charmspeak helped clear his mind and made his muscles relax, which he appreciated. Leo was not oblivious to her family stress and knew she was sensitive about both her godly and Cherokee sides of her family, though it was hard to keep track which made her more sensitive each day. The two and Jason cooperated well in defeating the Maenads and saving Camp. That night, Leo, Piper, and Jason drank hot chocolate at the campfire and Leo thanked Piper for saving him yet again. He enjoyed their company and they did a toast to friendship.

In The Mark of Athena, Piper wasn't angry at Leo when he fired on Camp Jupiter, and agreed that it couldn’t have been him, and could recognize the cold feeling he felt. Piper also figured out that Leo was possessed by Eidolons. Leo thanked Piper for not hating him after firing on the Romans, and Piper said it was okay, and he wasn't in control of himself. Leo said she didn't have to stand up for him, and Piper said of course she would, he was the annoying little brother she never had, showing how much she cared for him. Leo also teased Piper and said she had power ranger pajamas, and Piper said they were Cherokee Eagles. When Leo went missing in the Atlantic Ocean, Piper didn't sleep that night and looked in visions in Katoptris to find him. When Leo returned, Piper cried and freaked out, jumping in the ocean to greet him. She gave him a sisterly kiss on the cheek, with surprised him, and asked where he was. Piper wasn't afraid to lecture Leo, lecturing him when he didn't want to save Nico di Angelo and made Hazel upset. Leo saved Piper in Rome later on the quest, along with Percy, Jason, and Nico.

In The House of Hades, Leo wished Piper was with him at breakfast, since she had a way of calming people down, but she wasn't, she was with Gleeson Hedge. Piper and Leo also both wondered why Jason was suddenly defending Nico, since he didn't before. Piper recognized how Leo had changed over the months, and thought that he now knew how to use his nervous energy he had bottled up. Piper was heartbroken when Leo was shot up into the sky by Khione and demanded to know where he was. The idea of her never seeing Leo again made it hard to breathe and almost destroyed her. Piper was overjoyed when she reunited with Leo in Malta and tacked him with a hug. Piper was also concerned as to where Leo was and questioned him, but Leo brushed her off and said he didn't need an extra mom.

In The Blood of Olympus, Leo and Piper were close and Piper knew whenever Leo was lying. Piper trusted Leo and told him how worried she was about Jason, which she didn't tell anyone else. Leo also recognized how Piper had changed in the last few months, and her Charmspeak was so powerful it made Leo nervous. He thought that if she asked Leo to eat his vegetables, he may actually do it. Leo was also the first person to compliment Leo on Piper's singing when she sang to Kekrops. Piper gave Leo a sisterly kiss on the cheek when he fished out the key for Asclepius's palace, He later went into Asclepius' palace in Epidaurus with Piper and Jason, and they defeated an Automaton of Hygeia. However, Leo kept his suicidal plan to save everyone a secret from Piper, and had Hazel give her a mist version of the cure and refused to tell her what Asclepius told him. Leo and Piper defeated Gaea, along with Jason, and Leo's last words were that he loved Jason and Piper. Jason and Piper looked for him, but couldn't find him. She was originally mad at Hazel and Frank when they kept his plan from her, but she agreed that it was a plan Leo would've done. Piper said that if he was here, she would kill him, and wondered how Leo took the cure alone. Piper and Jason then spent a night talking about Leo, and Piper hoped that Leo was alive, and out there. She felt guilty about his death and replayed the scene in her head, and felt like she failed him.

A month after, Piper got a parchment scroll that revealed Leo's location. She and Jason spent a month looking for him, until Chiron convinced them to stop so they could go to school. In The Hidden Oracle, and The Dark Prophecy, Leo expressed interest of seeing Piper again. Piper was very excited when she found out Leo was alive and shook Apollo after he told her. Piper and Leo finally reunited after Jason died and Piper hugged Leo and sobbed into his shirt, mourning for Jason. Piper expressed interest in Leo's life and whereabouts, and Leo told Piper that Hazel, Frank, and Reyna were okay. Both Leo and Piper were proud of each other and where they ended up, and Leo decided to escort Piper to Oklahoma with Gleeson Hedge, Chuck Hedge, and Mellie.

Percy Jackson, one of her good friends.

Piper heard about Percy in The Lost Hero, and they met formally at Camp Jupiter in The Mark of Athena. Their first formal exchange was when Percy made a joke about "dam", and Piper didn't understand it, and Percy said it was an inside joke. They formally got to know each other the next day when Percy smiled at her to greet her, which she was surprised by. She was happy to see Percy with Annabeth since Annabeth felt truly happy being with him for the first time in months. She thought they were so easy together that it made her heart ache. However, Piper thought that Percy was unimpressive compared to Jason, and thought it was underwhelming seeing him after hearing so much about him for months. He wasn't Piper's type and thought he looked like a skater boy, a troublemaker, and if she saw him at a mall she would steer clear of him. But Piper could see why Annabeth liked him and knew why he needed her in his life, and thought if anyone could control a guy like that, she could. They cooperated well in Kansas and Piper was impressed when he summoned Blackjack, and she saved him twice from Eidolons. Piper was worried that Percy wouldn't trust her for knocking him out twice, but Jason reassured her that Percy wouldn't hate anybody. Piper was also relieved the next day when Percy and Annabeth came back from kissing in the stables.

As for Percy, he trusted Piper and felt responsible for everyone on the ship, including Piper. In Rome, Piper comforted Percy when Annabeth went off on her own and reassured him that Annabeth would be fine, putting Charmspeak in her voice. Piper also saved Percy's life from being drowned by Hagno. In return, Percy saved Piper from Otis and Ephialtes. Percy also asked how Piper's arm was after the battle, and Piper said it wad good and that he and Jason did great in the battle. Piper was upset when Percy fell to Tartarus, but she knew it wasn't her fault.

In The Blood of Olympus, Piper and Percy were friends and Percy was worried when she wanted to fight Mimas with Annabeth alone. However, Piper was afraid of the son of Poseidon. Piper knew that Percy had bad spirits inside him and after he exploded the toilets without trying, she wanted to leave the ship as soon as possible and wondered what he would like if he tried to act scary on purpose. Piper secretly felt uneasy when Annabeth told him how he tried to choke Akhlys with her own poison. However, they were still good friends and Percy got everyone, including Piper, gelato in Delos. Percy, Piper, and Annabeth headed to the Parthenon together to defeat the Gigantes, and Piper encouraged Percy to talk about his family. Percy also gave Piper water to heal her dry throat. When they made it to the Parthenon, Percy and Annabeth kissed passionately and though Piper felt awkward, she thought his relationship with Annabeth was the perfect example of love. Percy apologized, and Piper grinned and said he was a great boyfriend, approving of his relationship with Annabeth. Piper was very worried when Percy got a nosebleed and the blood of Olympus spilled.

Piper and Percy remained in contact, going to monthly Argo II reunion parties. In The Burning Maze, Piper was very worried about Percy and asked Grover Underwood if he was okay. In The Tower of Nero, Percy agreed that Piper was a tough lady.

Annabeth Chase, one of her best friends.

Piper and Annabeth met for the first time when Annabeth rescued Piper, Jason, and Leo from the Grand Canyon in The Lost Hero. Piper was angry at Annabeth at first when she called her a Half-Blood, since she is mixed race, but she calmed down when Jason explained what it meant. Piper and Annabeth later took a walk, where Annabeth told Piper about camp and being a demigod. Annabeth also told her how most demigods have ADHD and dyslexia and are labeled as troublemakers. Annabeth also told Piper how her memories about Jason were manipulated by the Mist, and Piper told Annabeth all of her fake memories about Jason. Piper cried, and Annabeth comforted her, telling her she can relate losing a boyfriend. Annabeth also helped Piper pick out her weapon, Katoptris. Piper mentioned that Annabeth would make a cool friend in better times, and hoped she would be claimed by Athena, so they can be in the same cabin together. Annabeth was furious when Rachel told her that Hera took over her body.

As they spent more time together, they became friends by the end of the book, with Annabeth standing up for Piper when Drew called Piper dense, saying that she asked a fair question. Piper could also read Annabeth's emotions very easily. Piper also told Annabeth that the prophecy and her losing Percy are connected, but was not mad at Annabeth when she decided to not go on the quest. Piper thought that Annabeth would be a great friend in better times.

By The Mark of Athena, Piper and Annabeth had become close friends and helped build the Argo II with Jason and Leo, and had created an inside joke where they steal each other's breakfast. Annabeth also loved Piper's charmspeak, which filled her with the desire to have a long talk with her and drop her dagger. Annabeth knew Piper very well and could tell what she was feeling, and she hated how oblivious Jason was to Pipers jealousy towards Reyna. In return, Piper never had a better friend than Annabeth was, and was glad to see her happy with Percy near her. Annabeth confided in Piper how Percy being missing was consuming her every waking moment and tormenting her. Piper was a little jealous of Annabeth's relationship with Percy however, because they got along so easy, it made her heart ache, but it didn’t affect their friendship at all. Piper even stressed out about the Prophecy of Seven because she could imagine what Annabeth would be like if Percy died. Annabeth also looked to Piper first to heal Percy, Jason, and Leo, when they were possessed by Eidolons. Piper likes Annabeth the way she is, noted when Aphrodite wanted to give her a makeoverm, Piper couldn't think of anything wrong with her. Piper cannot imagine Annabeth doing anything vengeful. However, Piper became slightly worried at the notion that Annabeth would become vengeful towards Jason, and wished they were not rivals.

When the Argo II made it to Charleston, Piper, Annabeth, and Hazel decided to go on a girl's adventure, and Annabeth didn't mind hanging out with Piper. Annabeth could tell that Piper was afraid to tell her what she had seen in the blade of [[Katoptris]. Piper was also the first person (plus Hazel) to find out about Annabeth's falling out with Minerva. Piper and Annabeth later sent a dream vision to Camp Half-Blood together, warning Chironabout the Romans. Piper began to greatly appreciate Annabeth even more on the voyage to Rome, when she appreciated how she and Jason began to trust each other and how she was taking up such a huge responsibility with the Mark of Athena. She reassured Annabeth when she was worried, saying that she was going to kick some serious booty, because she could tell she was terrified and trying to hide her terror. After Annabeth defeated Arachne, Piper knelt next to her and worried about her cast on her foot. Piper was devastated after Annabeth fell to Tartarus, but she knew it wasn't her fault or anyone elses.

In The House of Hades, Piper was sad and devastated about Annabeth being in Tartarus and shed some tears about her with Hazel. However, Piper was determined to rescue her friend at Epirus. While fighting Khione, Piper thought about what Annabeth would do. She revealed that she thought Annabeth was clever and great at devising plans, and didn't think she was as good as she was. When Piper first saw Annabeth again, she threw her arms around her and cried.

In The Blood of Olympus, they were closer than ever. Piper thought that Annabeth was the bravest person she ever met and had a lot of love for her friend. Annabeth had confided in Piper about the horrible things that happened in Tartarus, like Percy suffocating the goddess Akhlys. Annabeth and Piper went with Jason to Odysseus's Palace in Ithaca to find information regarding Gaea. The two later went to Sparta together to defeat the giant Mimas, and get the Makhai for the Physician's Cure. The two went to museums together while looking for him. While looking for Mimas, Piper could tell that Annabeth was worried about Percy and reassured her that Percy was smiling more and adjusting. Annabeth ended up breaking down and crying to Piper about how helpless she felt seeing the god Tartarus, her anguish of Percy disappearing, and how angry and scared she is about everything. Piper comforted her by talking to her and taking her hands as she cried. Annabeth then called Piper a good friend and said she’s angry at her for being annoyingly calm. When they made it to Mimas, Piper gave Annabeth advice to not think, just feel and only think about revenge for Bob and Damasen, and cupped her face and had their foreheads touch to calm her down. As for Piper, she fought while thinking about her love for Annabeth.

After Piper and Annabeth faced Mimas at Sparta, Annabeth began seeking Piper for advice and guidance more. They also learned they could tackle problems together from two different sides. When Kekrops arrived to lead them to Gaea, Piper and Annabeth both agreed that it was a trick. When Annabeth heard Piper's singing, she was amazed and told her it was incredible. Piper later encouraged Annabeth to talk about the family that she would miss, causing her to open up about her family in Boston and the family she used to resent. Piper thought how grateful she was to have boarded the Argo II because without it, she would've never became best friends with Annabeth. After she defeated Gaea, Piper, Annabeth, and Reyna became inseparable as they helped the two camps get along. Annabeth came to admire Piper as a mediator between conflicts. The two are still in contact, and meet up for monthly Argo II reunion parties.

In The Burning Maze, Piper thought of Annabeth as her best friend and asked Grover Underwood if she was okay. In The Tower of Nero, Annabeth wondered if Piper was okay and wished she was there for her after Jason died.

Hazel Levesque, one of her best friends.

Hazel and Piper met and befriended each other in The Mark of Athena. Piper wondered what Hazel thought of Camp Half-Blood and wondered if it seemed alien to her or if it made her miss Camp Jupiter. Piper also quickly realized that Hazel and Leo had a history, and that he was competing with Frank for attention. Hazel also winced at Piper when Jason was acting clueless of Pipers feelings about Reyna. When Piper could sense Eidolons in the room, Hazel said that Piper was right because Hazel had met Eidolons before in the Fields of Asphodel. Hazel and Piper helped defeat the Eidolons and Hazel commanded them to obey Piper, and gave Piper a look of encouragement. Later, Piper was determined to save Nico di Angelo since he was Hazel's brother, and put her hand on Hazel’s shoulder, reassuring her. Piper later lectured Leo and Jason for not wanting to save Nico, saying they were cold and that Hazel’s brother was dying. Hazel and Piper later went to meet Aphrodite with Annabeth, and was embarrassed at her mother for insulting Hazel's clothing, thinking nothing was wrong with how she dressed. When Hazel went missing, Piper stared into Katoptris for hours trying to find a vision of her, and cried with relief when she was found, jumping in the water to greet her.

In The House of Hades, Hazel and Piper bonded for the first time when they distracted Sciron's turtle to protect the ship, and they both went on Arion as they zipped around the turtles head. Hazel also wished Piper was with her when she helped defeat Sciron instead of Jason. After the experience, Hazel and Piper began hanging out more and talking about the boys gross habits, being the only two girls on the ship, and shed tears about Annabeth. Piper also learned from Hazel how controlling the Mist was similar to Charmspeak. Piper offered to help Hazel control the Mist, and in return, Hazel helped Piper with her swordfighting. Piper felt like she had a new friend and hoped Hazel was okay when she was nauseous one time. After the Argo II was stuck in North Africa for a week, Hazel and Piper spent hours a day swordfighting, true to Hazel’s promise. Later, Piper helped Hazel defeat Clytius. The night after they came back from rescuing Annabeth and Percy, Piper and Hazel practiced swordfighting.

In The Blood of Olympus, Hazel and Piper were very close friends, and Piper promised to teach Hazel to surf, in case they survived their quest. Piper trusted Hazel's mist magic the most when she went to Ithaca. Piper was also very supportive of Hazel’s relationship with Frank. And when Piper was going to the Parthenon underground, Piper was very grateful for Hazel and considered her one of her best friends, and that without her or Annabeth, she wouldn't of been able to discover her own courage or sing to Geminus. Hazel and Piper confided in each other, with Hazel telling Piper her worries about Jason being the linchpin to Hera's plan. As for Hazel, Hazel was very close to Piper but kept Leo's suicidal plan from her, at his insistence, and felt very guilty when she gave a fake version of the cure made from the mist to Piper. After Leo’s death, Hazel broke down and told Piper to take out the cure, and then Piper glared at Hazel when the cure was gone. Piper was originally angry at Hazel for not revealing Leo's plan, but couldn’t stay mad at her while she was crying and agreed that it was exactly a plan Leo would've done.

After the Romans left Camp, Piper missed Hazel and felt that Camp was empty without her and the other Romans. However, Hazel and Piper remained in contact and met for monthly Argo II reunion meetings. In The Tyrant's Tomb, Hazel was angry when Jason died because of how close Piper and Jason were, and asked his coffin how he could do this to Piper.

Frank Zhang, her good friend.

Frank and Piper met in The Mark of Athena. Frank and Piper seemed to have befriended each other and Piper wondered what Frank thought of Camp Half-Blood, if it seemed alien to him, if it made him miss Camp Jupiter, or if it made him be unfair about the lack of acknowledging the Romans. Piper could also tell that there was tension between Frank, Leo, and Hazel. Frank also agreed with Piper that he wasn’t sure if Reyna could stop Octavian. Frank later became slightly miffed at Piper when she told him to wait to comfort Hazel, because she says she needed time to cool off, making Frank huff like an irritated bear. However, Piper greatly cared about Frank in a short amount of time, and when he got missing, she stared in Katoptris for hours trying to locate him, and didn’t sleep that night. When she found him the next morning, she cried with relief and jumped in the water. Piper also reassured Frank that it wasn’t his fault that Percy and Annabeth fell into Tartarus.

In The House of Hades, Frank tried to be there for all of his remaining friends, including Piper, since Annabeth was gone. Frank also would forget that Piper’s father was Tristan McLean, and thought she was down to earth for a daughter of a movie star, which was fine with Frank, since he didn’t want paparazzi taking pictures of his epic fails. Frank was also curious as to why Piper wasn’t great with cows, but decided not to ask. Piper also thought that all of the boys, including Frank, had gross habits and complained about them to Hazel, due to being the only girls on the ship. Piper and Frank cooperated well in the House of Hades, and agreed that they both didn’t like cows. Piper also listened to Frank when he told her to distract the female Empousa. When they were done, Piper was in awe of Frank, and called him terrifying, but amazing, and helped bandage his wound. Piper also bragged how amazing he was to Reyna.

In The Blood of Olympus, Piper respected Frank as the co-leader of the Argo II, along with Annabeth. The two did some bonding when they went to Pylos to get the Pylosian Mint. Before they met his ancestors, Piper took Frank shopping to buy some new clothes and reassured him that he didn’t have to buy baggy clothes to hide his bulkiness anymore, and said he hadn’t changed, he was just more himself. They also killed giant warthogs together. Piper waited for Frank while he met with his ancestors and when he came out, Frank confided to Piper how they acted cold and distant around him because he was Chinese and a son of Mars. Piper told him that his cousins were idiots and they didn’t know how great he was. When they went back to the ship, Frank said it was nice killing warthogs with her and Piper agreed, and gave him a hug, which seemed to fluster him. Piper revealed that she couldn’t help liking Frank, since he was a kind and considerate boyfriend to Hazel and he had shouldered the title of Praetor, taking that responsibly off of Jason.

At Leo’s insistence, Frank kept Leo’s suicidal plan from Piper. When Piper found out, Piper was angry at Frank, but her anger subsided because she couldn’t be angry while Frank was crying, and she agreed that that is a plan Leo would’ve done. After Frank left Camp, Piper missed him, feeling like Camp was empty without him and the other Romans. The two kept in contact, meeting for monthly Argo II reunion parties.

Nico di Angelo, her friend and ally

Piper first learns about Nico in The Mark of Athena, when she learns he is dying, but only thinks of him as Hazel's brother. However, even after Piper found out it was a track, she was still determined to save him, and reassured Hazel that she would. Piper also decoded what Nico was in the prophecy and how he must have found the Doors of Death. After Jason and Leo opposed rescuing him, Piper lectured them, saying that was cold and that Nico was dying, and went to comfort Hazel. While crossing the Atlantic, Piper was anxious to reach Rome to save him, and imagined what Nico was feeling- stuck in a jar with only two seeds left, no idea if he would be rescued. However, when Piper saw a horrifying vision in Katoptris that hinted at Piper, Percy, and Jason dying on the way to Nico and saw that saving him was too easy, Piper briefly hesitated saving him, but still wanted to save him and saw a vision of him lifeless, making Piper hope he was still alive. After Nico was let go, Piper shielded Nico from leopards attacking him and defended him. Piper then tried to pull Nico to safety, injuring herself in the process, signifying how Piper was willing to sacrifice herself for him. After Nico was rescued, he thanked everyone, including Piper, and said he had given up hope. Piper later asked Nico where in Greece the Doors of Death were. After Annabeth and Percy fell into Tartarus, Nico agreed with Piper that it wasn't Frank or Jason's fault that they fell into Tartarus.

In The House of Hades, Piper and Nico appear to be on good terms, with Piper trying her best to include him. However, Piper thought that he had a crush on Annabeth, and mentioned that to Jason. She offered to go to Dalmatia with Jason and Nico, but Nico objected to her going, saying that Diocletian may appear to Jason or him, but not to anyone else, because Piper might spook him. After Croatia, Piper noticed that Nico was acting nervous and cagey, like something major had happened there, and worried about him. Piper became concerned when he kissed Hazels cheek, since he hated physical contact, and thought he was almost saying goodbye. Piper also felt Nico’s defenses going up, afraid of what him or Leo would say about him when he was gone. However, Nico and Piper cooperated well going into the House of Hades and when Piper said the doors opened every fifteen minutes, Nico corrected her and said every twelve, and discussed a lot while walking. When they fought monsters, Piper stood at Nico’s back, and was concerned after he almost fell.

In The Blood of Olympus, Piper cared about Nico, and reassured Jason that he, Reyna, and Coach Hedge would be fine, and told Jason that after the war ended, everything would work out for Nico and that Jason had done what he could, being a friend to him. Piper could sense what was happening with Nico due to being a daughter of Aphrodite, sensing people’s heartache, but never pressured Jason to talk to her about it. Later, when Piper met Zeus for the first time, she immediately asked him if Nico, Reyna, and Hedge were okay. Piper also believed Nico when he said that Leo indeed died. As for Nico, Nico greatly appreciated Piper for everything she had done for him, welcoming him on to the ship and saving him in Rome, and when he found out one of the Seven may die, including Piper, he felt empty, like he was back in the bronze jar. Nico was very worried about Piper when Octavian wanted to fire an onager, and warned him not to, because either Piper or Jason would get hurt.

Apollo, a friend and god she quested with

Even though Apollo and Piper first met in The Blood of Olympus, they first had a conversation in The Burning Maze, when Apollo needed her help to go through the burning maze. Piper was very surprised when she found out that Apollo was mortal, and Apollo told Piper his quest thus far to become a god again. Piper shook Apollo's shoulders when he told her that Leo was alive, though Piper apologized after Apollo said it hurt. Piper, Meg, Grover, and Apollo then discussed on the terrace, and Piper told them about what the Triumvirate Holdings did to her family. Apollo could tell that something happened between her and Jason and questioned her on it, and was shocked to find out they broke up, but Piper said that not all relationships last like Percy and Annabeth. Piper agreed to help Apollo and they became friends. Apollo was very impressed with the daughter of Aphrodite when she had a blowpipe, and he exclaimed that he loved blowpipes. He became even more impressed when he found out she had Katoptris, the dagger that belonged to Helen of Troy. Even after only knowing her for a short amount of time, Apollo could tell that she holding back a lot of feelings, doubts, and personal feelings from her time in the Labyrinth. Piper also saved Apollo from Medea.

Eventually, after Piper and Apollo went on the Julia Drusilla Yachts, they split up from Jason and Meg to go find the shoes they need to go into the Burning Maze. Apollo was skeptical at first going alone with Piper, but Piper told him to not underestimate his fighting skills. While they were on one of the yachts, Apollo helped Piper sing "Life of Illusion". Apollo was very surprised by Piper's beautiful voice, and even more surprised by the sadness in the tune she chose, making every note he played on his ukekele a note of sympathy for Piper. When they made it to the next yacht, she forced Piper to rest and gave her a minute to rest, and carried her inside Yacht 40. On the yacht, Piper confided in Apollo how the song she sang was from her happiest memory. Piper then told Apollo the reasons why she broke up with Jason, and how she had so much pressure to conform. Apollo gave Piper advice, and said even though she can choose how much ancestry she can embrace, and she can overcome the expectations on her family and her society, she cannot try to be someone other than herself. Piper was grateful for his advice and asked if he wasn't the god of wisdom, and Apollo joked that he applied but didn't get the job. Piper burst out laughing, and Apollo was grateful for his new friendship and could not recall the last time she had such a positive exchange with an equal. Apollo later became very concerned when she was knocked out by Incitatus, and even tried to kill himself to save Piper, Meg, and Jason.

However, Piper and Apollo’s newfound friendship deteriorated after Jason died. Apollo tried to give Piper Ambrosia and Nectar to heal her but she slapped it out of his hand, dazed with grief. Piper was frantic to have Apollo heal Jason and tell her ways to heal him, but Apollo had to tell her there was no way to bring him back, as she begged him to help her. Piper lashed out at Apollo in anger and accused him of not caring about Jason's death because he is a god, and that he was using her to get what he wanted, just like all the other gods. Piper angrily gave him the shoes they needed, saying they got Jason killed. And after Apollo, Meg, and Crest went to call 911 for Jason, Piper told Apollo to never come back and screamed for him to go. Apollo felt very guilty and thought he had failed his new friend.

Even though Piper blamed Apollo for what happened to Jason, Apollo had no anger towards Piper. However, Piper managed to let go of her anger enough to save Apollo and his comrades from Medea and Helios, though it was her second priority after getting revenge on Medea. Piper smiled and greeted Apollo and his friends after she killed Medea, and knelt next to Apollo in sympathy after Crest died, telling Apollo to grieve later, since their job wasn't done. Apollo then leaned on Piper, who helped him walk across the room. After they left the Burning Maze, Piper gave Apollo a paper and told him to meet her tomorrow to work out the arrangements of Jason's death.

The next day, Piper met Apollo and Meg at the airport, and Piper revealed she booked Apollo a flight on her private jet to get to Camp Jupiter, quickly to bring Jason home and for him to meet Reyna Ramírez-Arellano. Piper also trusted Apollo enough to give him Jason's sketchbooks of the designs of temples for the gods. Apollo still felt extremely guilty for what happened and was thankful that Piper did everything to help him, but knew he could never repay her or compensate for all that she lost. Apollo tried to apologize, but Piper quickly said it was fine and told him to get Jason to Camp Jupiter like he deserves and to stop Caligula. There was no bitterness in her voice, and it was arid, with no judgment, like the Palm Springs heat.

In The Tower of Nero, Apollo was very grateful for all that Piper had done for him and felt that he needed to repay her everything. Apollo considered Piper as one of his friends and told Percy and Annabeth that she was a tough young lady. After his godhood was restored, he went to visit her in Tahlequah and walked in on her kissing Shel, her girlfriend, on a roof. Apollo was so shocked that he accidentally turned from his Lester form to his Apollo form. Piper was awkward from the moment and told Apollo it was bad timing, and Apollo quickly apologized. She told Shel it was an old family friend and ex used herself to talk to Apollo for a second. Piper asked him what was up, and Apollo said he just wanted to check on on Piper and see if she was okay. Apollo realized, after seeing her with her girlfriend, what she was talking about when they were on the Julia Drusilla Yachts. Apollo said he was happy for her and asked how her dad was, and in return, Piper congratulated Apollo for making it back to Olympus. Apollo told her what happened with Nero and that she brought Jason home. Piper said she was glad that he brought Jason home and said he did right by him and they both bonded over how they would never forget what happened to him. Piper than excused herself to go back to Shel and told him to give him a heads up next time before popping in. Apollo muttered something apologetic, but she was already back with Shel.

Coach Hedge, her close friend and protector

Coach Hedge and Piper knew each other while he was her protector at the Wilderness School. Coach Hedge was very protective of Piper and kept her from being bullied by popular kids at the Grand Canyon. He would also push Piper very hard during gym class, and let her fight her own battles when she was bullied. Piper, in return, was very difficult towards him and had fake mist memories of setting his pants on fire. Coach Hedge eventually sacrificed himself to save Piper, Leo, and Jason. Piper never liked him much, but she was extremely grateful for him for saving her and couldn't believe that he would. Piper was very worried on what happened to him and questioned Annabeth, and couldn't fathom that he may have been reincarnated as a flower. Over the course of the quest, she realized that all of the times Hedge pushed her was to prepare her for difficult life as a demigod, and after she found out that he was alive, she felt a strong compulsion to save him. Piper then saved him from Medea in Chicago and helped open his cage in Omaha.

After Coach Hedge woke up, he thought it was destiny to protect Piper and her friends and decided to join the quest with them. Coach Hedge was very protective of Piper during the quest and helped heal her hypothermia with sports medicine, which Piper thanked him for. Piper even complimented the Coach when she said something smart, and joked that it was "almost an intelligent comment". Coach Hedge did not judge Piper when she told him the truth about her father, and reassured her that Tristan McLean wasn't dead. Coach Hedge also protected Piper again after she passed out from hypothermia, catching her, and carrying her to be healed by Phoebe and the Hunters of Artemis. Piper was very surprised at the end of the quest when Coach Hedge offered to take her father home, thinking he was the last person to offer. He said that he was a protector and she needed to carry on with her quest, and that he can handle this. He hugged Piper before he left then glared at Leo and Jason, telling them to protect her. She gave him another hug, telling him to protect her dad, and he reassured her yet again.

After the quest was over, Piper iris messaged Hedge to talk to him. Hedge grinned at her as soon as he saw her. It is revealed that he is working for her dad as his life coach, and is now living with the McLean family. He promised that he would make sure that Tristan rests and talks to Piper while keeping him out of the public eye. Piper was amazed and supportive when she found out he was dating Mellie, who was her dads new assistant, and thanked Coach Hedge for everything.

By The Mark of Athena, Hedge was very close to Piper and the McLean family and made sure Mellie protected the household while he was gone. Coach Hedge is even more protective of Piper than Leo and Jason, two other demigods he was close with. As for Piper, she was extremely grateful for everything he did for her- saving her father and helping him get back on his feet. Coach Hedge tried to hide it, but Piper was pretty sure he came along with her on the quest was because her father encouraged him to come along and protect her. Piper thought of him as a weird chaperone and the most warlike goat she ever met, but still deeply cared for him. During the quest, Piper learned to be appreciative of his healing skills, like when he healed Percy and Jason after being possessed by Eidolons. In Rome, Coach Hedge watched over Piper and Jason during their date and told them to stay where he can see them. Before she left with Percy and Jason to rescue Nico di Angelo, she even trusted him enough to watch Katoptris, her prized possession. Coach Hedge told Piper to be back soon or he would come after her with ballistae.

In The House of Hades, Coach Hedge and Piper took a turn at the helm together, where they were tied up by Akmon and Passalos. Piper became very concerned with the Coach when he was calling Mellie a lot and acting agitated about her, though she wouldn't tell him why. Hedge was extremely impressed with Piper after she defeated Khione, and bragged to Leo, saying she had skills, though he exaggerated her story. In The Blood of Olympus, Piper knew that the Coach would be fine and that he, Nico, and Reyna were a tough bunch.

In The Burning Maze, Coach Hedge was laid off from being Tristan's life Coach and didn't see Piper that often, since she was busy with school and quests, and Mellie didn't want him to see her because it would break her heart after what happened to her family. Coach Hedge still deeply cared about the McLean's, however, and told Apollo, Grover, and Meg to give her his best when they saw her. He felt very bad for Piper after what happened to her family, and hoped she wasn't evicted before she moved to Oklahoma. Coach Hedge was very worried about her after she fought Medea and urged her to drink more water. As for Piper, she was very close with the Hedge family and he even let her play with his son, Chuck Hedge, who sat on her lap. But Piper never told Hedge the whole truth about what happened with Jason, because it rattled her too much. The next day, Hedge wanted to accompany Piper to meet Jason, but Mellie quickly un-volunteered him.

After Jason died, Coach Hedge's primary concern was for Piper and he immediately asked Apollo for the car keys and took Mellie to go see her, saying that Piper needs them and he needs to care for her. After the incident, Coach Hedge and his family decided that they would not be staying in California, and would instead be moving to Oklahoma with the McLean family, saying he could find a job there even though he wasn't Tristan's life coach anymore. Before they left, Coach Hedge was grim and determined to protect Piper on the way and asked her if she was ready. Piper wondered if his car was ready for such a long trip, and Coach Hedge reassured her that it was, though Mellie was distrustful of that and rode with Piper in the SUV.

Family

Tristan McLean, her father.

Besides, if those girls found out the truth about her dad, they’d be all bowing down to her and screaming, ‘We’re not worthy!’

Leo about Piper's dad, in ‘‘The Lost Hero’’.

Piper's father is Tristan McLean, a well-known actor with a powerful position and is of Cherokee descent. Her father is always at work and busy. Piper wants to feel recognized by him which is why she gets in trouble and "steals" things with her charmspeaking. The two share a moment during The Lost Hero, where he explained that while he does love her, he tried to keep her away from him so she wouldn't be drawn into his crazy celebrity life. From then on, Piper is more understanding of her dad and accepts that he may not have as much time for her as she would like.

Aphrodite, her mother.

Her mother is Aphrodite, who is as known as the goddess of love and beauty. When Piper meet her mom in her dream, the two seemed to act on good terms with each other and she thinks her mother is beautiful. In The Mark of Athena she admits feeling a little hurt that her mother paid almost no attention to her when Hazel, Annabeth and Piper meet up with Aphrodite/Venus. Aphrodite also states that she's trying to make their love life "interesting," but in other words, it just means she's making it hard, as Piper thinks. In The House of Hades, Piper is able to defeat Khione when she remembers how great and powerful her really mother is, which motivates and enhances Piper's powers to the point that she uses the love of her heart to melt Khione's ice.

Piper also had a grandfather called Grandpa Tom. He was the one who named Piper. He named her that because she had a loud, strong voice.

Lacy, her half-sister.

Lacy is a young girl in the Aphrodite cabin. She helps Piper by building up a collection of clothes for Piper before she leaves on her quest. She is exuberant when Piper takes Drew's place at the end of The Lost Hero.

Another cabin-mate of Piper. He also helped Piper when she first arrived, and not in trouble with Drew after saying that Piper didn't seem so bad at all. Mitchell, like Lacy was exuberant when Piper took over the cabin from Drew at the end of the The Lost Hero.

Etymology

  • Piper is an Old English name meaning "pipe player," a possible reference to her ability to charmspeak and the story of the pied piper. According to her Grandpa Tom, he named her that as she had a high vocal voice when she was a baby, also saying that one day she was going to play the biggest tune of them all. Piper is also a synonym for a squab, particularly that of a dove or pigeon. Interestingly Piper's mother is called "Lady of Doves."
  • McLean is a Scottish or Irish surname that is a variant of the name "McLain", which is rooted in the Gaelic "Mac Gille Eáin" meaning "son of the servant of John".

Trivia

  • She got her name because her grandfather thought she would one day master all the Cherokee songs, including the snake song. Her father liked the idea and named her Piper.
  • Percy, Piper, and Annabeth are the only demigods of the Seven whose mortal parents are alive.
  • She sometimes calls Jason "Sparky".
  • Piper was the first Head Counselor to be promoted, who had other siblings, in less than five days. She is also the first half-blood in both series to challenge another for the right to become Head Counselor.
  • Piper is a vegetarian.
  • Her cornucopia is able to channel her emotions and depending on their power, spill out more or less food.
  • Piper dislikes the term half-blood due to her being called one for years, as other kids made fun of her for being half-Native American and half-white.
  • Piper's role in The Lost Hero is vaguely similar to Hazel's in The Son of Neptune, as they both have a crush on a member of the quest, as well as possessing a dark secret. However, Piper is much more open about her crush than Hazel.
  • There is somewhat an inconsistency in Piper's clothing in the American cover of The Lost Hero. She appears to still be wearing the dress Aphrodite gave her when she was claimed while she already changed it prior to riding Festus and going to Boreas castle in Quebec.[1]
  • Unlike the rest of Aphrodite’s (known) daughters, Piper is a tomboy.
  • It is thought that her charmspeak saved Jason's life when he saw Hera's divine form. The actual reason this worked, though, was that Thanatos (Death) was chained at the time. This was revealed in The Son of Neptune.
  • She is called the "Mediator", by her mother Aphrodite, for when the two sides of demigods, Greek and Roman, will meet, she will have to mediate them, since she has the ability of charmspeak.
  • She is the only one of the new main characters to have her mortal parent still alive.
  • She is also the only new main character with a mortal father.
  • Drew calls her the Dumpster Queen (for her lack of form and her simple clothes, the very things Jason likes about her) and Miss Movie Star (for when she says her father is Tristan McLean).

  • Before receiving the blessing of Aphrodite, Piper had a pimple on the base of her nose that had been there for so long, she began to call it Bob. However, Bob disappears after her claiming.
  • In her official portrait by Antonio Caparo, an image of Enceladus is reflected in her dagger.
  • Piper's first chapter in The Lost Hero is the first time in both series we don't hear from a child of the Big Three.
  • Piper is the first female to have a point of view in the Camp Half-Blood series. She is also the second female in the Riordanverse to have a point of view, the first being Sadie Kane in The Kane Chronicles.

Rick Riordan revealed that Piper McLean was inspired by conversations he had with Native kids during school visits, he did hundreds over the years. The kids asked him if he could add a Native hero to Percy Jackson's world, they wanted to see themselves reflect at Camp Half-Blood because they never found themselves in popular kids' books.[2]
