The Lost Hero

The Lost Hero is the first book in The Heroes of Olympus, written by Rick Riordan. Unlike the other books, it is written in third person, following three different characters.

The Grand Canyon
Jason wakes up with no memory while on a bus from the Wilderness School, a boarding school for delinquent kids, with Piper McLean and Leo Valdez, who claim to be his girlfriend and best friend respectively. While on a trip to the Grand Canyon, a storm appears, and one member of the class, Dylan, transforms into a anemoi thuellai (Jason calls them venti) and summons med from a Roman coin that turns into a sword or a lance (depending on which side he flips it to) and saves a falling Piper with his abilities over the winds as Coach Gleeson Hedge, a satyr/faun who was assigned to protect the demigod students, saves Leo, but is kidnapped by Dylan after retreating to his 'mistress'. Two demigods, Annabeth Chase and Butch, son of Iris, come looking for Percy Jackson, who has been missing for three days, and collect the demigods on a pegasi-ridden chariot, taking them to Camp Half-Blood. Once there, Leo is almost immediately claimed by Hephaestus, god of fire and forges, and the three are taken on a tour of camp.

At Camp Half-Blood
Piper Mclean, who is worried about a dream in which her father has been kidnapped and must betray her friends to get him back, is shown around by a downhearted Annabeth, and is shocked to learn that her memories of Jason weren't real and that he wasn't really her boyfriend, before they find Rachel in the Hera cabin who is possessed by Hera and tells Piper to free her. Leo is taken by Will Solace to Cabin 9, which had been cursed since Beckendorf's death. None of their machines are working and the Bronze Dragon going haywire and hiding in the forest. Leo learns that possessing the powers of flame, a rare trait among Hephaestus's children, is a dangerous ability. Leo accidentally used his fire powers during his childhood and killed his mother, being provoked by Gaea. Jason is accompanied by Drew, the tyrannic counselor of Aphrodite, to Chiron, who is shocked at Jason being at the camp. Chiron says, "You are supposed to be dead." Jason has a vision of Hera asking him for assistance, and he learns from a Clovis, child of Hypnos, that his memories were actually stolen.

A Quest is Given
That night at the campfire, Jason proves himself to be a son of Zeus (though he initially calls him Jupiter) and accepts a quest to save Hera by the winter solstice in four days and return her to Olympus. A month earlier, Olympus was closed by Zeus and none of the gods making contact with anyone. Rachel issuing a new prophecy that demands the need for a child of Hephaestus and Aphrodite to free Hera. Leo volunteers and, shortly afterward, is able to obtain air transportation (since Rachel's prophecy warned them to "beware the earth") in the form of a fixed mechanical dragon, who he names Festus the Dragon, which means Happy in Latin. Leo equips a pair of wings on him in an underground workshop named Bunker 9 that Festus shows him. Drew volunteers to go on the quest as well, but Piper intervenes, and she is claimed by Aphrodite and asked by Jason to go on the quest.

Talk with Boreas
The next day, the trio leaves for Quebec, Canada to see Boreas, the North Wind, and try to figure out where to find Aeolus, master of the winds, and track down the anemoi and make them tell where Hera is imprisoned. They make it to Boreas's place, and meet his children - the immortal demigods Boreads, Cal and Zethes, and Khione the snow goddess - before seeing Boreas. The god tells them that Aeolus, angry at demigods for the storm spirit's release after Typhon's defeat, ordered that demigods be killed if the wind gods see them, but Jason tells them of their quest and shows him his mysterious tattoo, which causes Boreas to turn into his Roman art Aquilon and allows them to leave for Chicago, where they will find their next lead. They are detoured when three Hyperborean Cyclopes capture Jason and Piper, and Leo is able to save them using his flame powers after being contacted by a sleeping woman in the earth, who is the real reason for his mother's death.

Medea and King Midas
They continue to Chicago, where they enter an underground mall and meet Medea the sorceress, who has come back to life thanks to her 'patron'. Jason and Leo are unable to aid Piper to fight the sorceress because they were being charmspoken by Medea. Piper is able to fight her and knock her into a counter of potions, which explodes and destroys the mall after Jason, Piper, and Leo make it out on Festus with the cages containing the storm spirits and Coach Hedge. However, Festus is shot down in the middle of a mansion's courtyard and destroyed, and Leo asks his father to take the dragon's head to Bunker 9. The group makes their way inside, and the next morning, Hedge is freed from his cage and they discover the mansion is home of a revived King Midas and his son Lit by the work of his 'patron.' Lit battles Jason before being turned to gold by Midas, who is then trapped by a fallen chandelier as the rest of his gold-turned victims, including Piper and Leo, go back to normal.

Meeting with the Hunters
While resting in a mountain cave, the group is attacked by Lycaon and his group of werewolves, before being saved by the Hunters led by Thalia, who Jason believes is his sister. She explains that their mother was visited by Zeus twice and she gave Jason up to Hera at age two, shortly before Thalia ran away and their mother died while drinking and driving. Thalia decides to travel to the "Wolf House" with the Hunters to try and free Hera while the others try to free Piper's dad from the giant Enceladus.

Aeolus and the Real Enemy
They go up the mountain and are escorted by Mellie the aura (who develops a crush on Hedge) to Aeolus, who turns out to be a constantly changing weather reporter-type figure and claims to know Jason from before. Though Aeolus stops the order to kill demigods (he explains he was "just cranky") and the children's parents tell him to reveal the location of Enceladus at Mount Diablo, he hears a voice in his head that tells him to kill them. Millie and Jason are just able to save themselves with their wind powers and are transported to San Fransisco thanks to Aphrodite, who tells Piper in a dream of their true enemy - Gaea, mother titan of the Earth who is raising the giants and the dead in order to destroy the gods and fully awaken herself.

Mount Diablo
They get to Mount Diablo, and Jason, Leo, and Coach Hedge try to distract Enceladus while Piper frees her dad. The giant summons Earthborn to kill them, defeated by Leo and Piper. Jason fights Enceladus, having his lance destroyed in the process and unleashing an explosion that creates a large crater. Jason then prays for assistance from his father, and Zeus's lightning bolt transfers through Jason into the giant, who falls into the crevice it creates.

The Wolf House
The group manages to 'borrow' a helicopter, and Hedge takes Piper's father to safety as the demigods travel to the Wolf House, otherwise known as Jack London's home. The group crash-lands and joins the Hunters as they attack the house, infested with monsters. They find Hera inside a cage made from the earth with the giant Porphyrion using her power to reform himself. Before they break the cage, Khione, the goddess of snow, comes and reveals herself to be the reason for the giant's rise and Gaea's awakening by manipulating the god's thoughts. Leo fights her using his flame powers, and Jason goes one-on-one with the awakened Porphyrion as Piper forces it to sleep and Leo tries to break it in its weakened state. Jason manages to distract the giant long enough for Hera to be released and unleash her divine form, which Jason accidentally looks at. He apparently dies, but Piper is able to revive him, and Hera transports them to Camp Half-Blood.

Aphrodite Counselor Change and Bunker 9
Piper forces Drew to step down from being head counselor and replaces her. Leo shows everyone Bunker 9 and announces that he will build "Argo II". He also breaks the curse of the Hephaestus cabin.

Visit from Juno and Camp Counselor Meeting
While in Cabin One, Jason is visited by Juno, Hera's Roman form, who promises she is watching over him as his patron and gives him a new gladius to replace his old weapon before Annabeth comes to bring him to the council of cabin leaders. Jason reveals that both Greek and Roman demigods were never aware of each other because they always both hated and respected one another. He also tells them he was a leader of his camp and helped in the second Titan War by destroying Mount Othrys and defeating the Titan Krios singlehandedly. They decide to find the Roman camp, and Annabeth wishes to come with them, as they reveal Percy Jackson, as the leader of Camp Half-Blood, was traded with Jason to the Roman camp, and probably has no memory of who he is.

The Great Prophecy
"Seven half-bloods shall answer the call.

To storm or fire,the world must fall.

An oath to keep with a final breath,

And foes bear arms to the Doors of Death." -Oracle of Delphi, (Rachel Elizabeth Dare)

Jason's Prophecy
Child of Lightning, beware the earth,

The Giant's revenge the seven shall birth,

The forge and dove shall break the cage,

And death unleash through Hera's rage.

The prophecy unfolds throughout the story like this:

1. Jason, a child of Jupiter, has to beware the awakening of Gaea.

2. The Giants rise to defeat the Olympians and cause the appearance of the seven heroes of the Great Prophecy.

3. Leo and Piper, children of Hephaestus and Aphrodite respectively, break the cage Hera is trapped in.

4. Jason almost dies by Hera's hand, witnessing her transformation that would burn any other mortal or demigod.

Characters

 * Jason Grace: A 15 year-old son of Jupiter (or Zeus), god of the sky who's lost his memory. He is the younger full brother of Thalia. He comes from the Roman version of Camp Half Blood and he is their version of Percy Jackson. He has a golden coin, with a man's face wreathed in laurels on one side and a battle axe on the other, that turns into a golden sword, a lance, or a double-edged sword made of Imperial Gold depending on the flip and vice versa. He can manipulate the Mist, and survive lightning that would kill twenty men, though his shoe is blasted to bits (The original Jason lost a sandal, and found the Fleece). He can also manipulate air. Jason saw a friend being bullied and took an instant dislike to the bullies, though he couldn't remember them. Jason jumped off the Grand Canyon to save Piper, showing his courage and loyalty to his friends. He and Percy seem to share this fatal flaw (personal loyalty). He is the champion of Hera, and has tattoos on his arm showing the letters SPQR, an eagle, and twelve lines(His tattoos represent his time at camp and birth god like how camp half blood gives out beads when you complete a quest).
 * Leo Valdez: He's Jason's demigod best friend. He's very mischievous. He also likes to build things and is constantly busy with tools. He is the son of Hephaestus and a fire starter; the first in hundreds of years. He becomes leader of the Hephaestus cabin after his quest, and he's fooled by Jason's mist. He shows attachments to all his creations, mostly his dragon Festus.
 * Piper McLean: She's Jason's demigod girlfriend, and she is a daughter of Aphrodite who can charmspeak, a very rare talent used to seduce most victims into doing anything. She also becomes the head of her cabin after challenging Drew, the current leader. Her dad is the movie star, Tristan Mclean. She too is fooled by Jason's mist, though still decides that she still likes him afterword.
 * Gleeson Hedge: He's a satyr (or faun, as called by Jason) posing as a coach who was assigned to protect Leo and Piper. Once Jason is attacked, however, Gleeson decides to protect him. Previously, he tried to defend a park in Toronto from a giant evil badger. He is the only one who wasn't fooled by Jason's Mist. Earlier mentioned in The Last Olympian by one of the letters sent to Grover. He is later found in Medea's department store with a bunch of storm spirits. He accompanies them for the rest of the story and becomes Piper's Dad's Counselor.
 * Dylan: He is a cruel boy with blinding white teeth. He transforms into an Anemoi Thuelli,also know as a Ventus in Roman mythology. He is storm demon (a son of Typhon) or a storm spirit and tries to kill the Jason, Piper ,and Leo. He summons two other storm demons, but Jason slays them. Dylan kidnaps Gleeson Hedge. The monster says that his "mistress" will destroy all demigods, later revealed to be Gaea.
 * Butch: He arrives with Annabeth on a chariot pulled by a pair of pegasi. There is a rainbow tattoo on his arm, as he is a son of Iris. Leo makes fun of his love for rainbows and Pegesi, but stops when Butch threatens to knock him off the chariot.
 * Annabeth Chase: Daughter of Athena. Annabeth arrives in a flying chariot with a demigod named Butch, on account of the dream she received telling her to go there and find someone with one shoe in order to find her boyfriend, Percy Jackson, who has been missing for three days.
 * Percy Jackson: Son of Poseidon. He has been lost for three days and it is appearntly The Lost Hero, although Jason could be the lost hero, as he is lost in his memory. Percy is the main protagonist and narrator of the previous series, Percy Jackson and the Olympians. Percy was sent to the Roman Camp by Hera, without any memory, just as Jason had been sent to the Greek camp. In the last chapter, the leaders of Camp-Half Blood, along with Piper,Jason, and Leo decide to go to the Roman version of Camp Half Blood, so he will presumably be reappearing in Book two, The Son of Neptune.
 * Hera: Hera is found on The Lost Hero website in the characters section alongside the three main characters, the only Olympian god to be featured there. When Jason was 2 years old, she was given him to be her champion, by Jason's Mother. Captured by Gaea to be used to feed the giants return, she was the one who stole both Jason's and most likely Percy's memory.
 * Drew: Drew is a daughter of Aphrodite at Camp Half-blood. She can also charmspeak. She seems to dislike Piper very much, and have feelings for Jason. She was the leader of the Aphrodite Cabin at the beginning of the book before she stepped down toPiper. She is known as a tyrant of the Aphrodite cabin.
 * Thalia Grace: Jason's long lost full sister- meaning they have the same father and mother. She was mentioned in Chapter XIV (in the end) where Jason says his last name is Grace after he finds a picture of Thalia. In chapters XXXIV (in the end) and XXXV she is mentioned where she saves Jason's and his friends life from Lycaon and his Wolves and she finds Jason. Leo has a crush on her and she is frozen by Khione- goddess of snow.
