The Quest for the Golden Fleece was a search for the Golden Fleece taken up by Clarisse La Rue, daughter of Ares, who was handpicked by the camp's substitute activities director Tantalus (replacing Chiron in The Sea of Monsters), a ghostly prisoner from Tartarus, and one of Percy Jackson's least favorite people. Also, Percy, Annabeth Chase, and Tyson go after Grover in a desperate rescue for the satyr and in Plan B, the Golden Fleece, 'disturbing' Clarisse, who didn't want them interfering in their quest.
You shall find what you seek and make it your own,
But despair for your life entombed within stone,
And fail without friends, to fly home alone.
Unraveling the Prophecy
- Clarisse will use the CSS Birmingham in order to travel to the Sea of Monsters, assisted by the undead Confederate crew and Percy, Annabeth, and Tyson.
- Clarisse will find the Golden Fleece.
- Clarisse is trapped in a stone cave by Polyphemus the Cyclops.
- Clarisse travels to Camp Half-Blood by plane, alone with the Golden Fleece to get there in time, as Percy would not take it, as not only would he be knocked out of the sky by Zeus, but also because it was not his quest.
Clarisse was granted a quest to retrieve the Golden Fleece to cure Thalia's tree and save Camp Half-Blood. The location of the fleece was found to be in the Sea of Monsters which mortals know as the Bermuda Triangle. The island that held it was owned by Polyphemus, a very ugly, beat up, and undisciplined Cyclops who refused to let go of the fleece and had also trapped Grover. So Percy, Annabeth, Clarisse, and Tyson fought the Cyclops in a decided plan of attack to escape - Attack Plan Macedonia. With a few injuries, they made it safely out of the Sea of Monsters to Miami, Florida even with Annabeth's broken ribs (Polyphemus dropped her by Percy's demands onto the ground head first causing Annabeth's ribs to break a bit).
Thereafter, in Miami, Annabeth discovers that the date is June eighteenth, three days after they've been in the Sea of Monsters and Grover whimpers that Thalia's tree would soon be dead. Clarisse, realizing that they've been in the Sea of Monsters for three days but on Percy's delays, turns on Percy and blames him for the three day delay that he caused on her quest. However, Annabeth rushes to Percy's rescue and shouts at Clarisse for not realizing the exact truth: she and Percy had to help her on the quest as friends because if they didn't Polyphemus would've kept the fleece longer and the fleece would've stayed hidden forever. Therefore, Clarisse relents her yelling on Percy and, in return, Percy gives her the money to ride a plane as quick as possible from Miami to Manhattan before Thalia's tree dies.
After Clarisse is gone, Percy tells Annabeth, Tyson, and Grover that they can find another way back to Camp Half-blood. However, before they leave Miami, they bump into Luke Castellan and his army of enemy demigods and monsters. Luke then welcomes them onto his cruise ship, The Princess Andromeda as an act of hospitality. After they get on his cruise ship, Luke demands that they turn over the Golden Fleece. Grinning and cheerful, Percy cannot help but tell him without hesitation that they had sent it to camp earlier. Luke, realizing that Percy had given it to Clarisse so she could deliver it to Camp Half-blood, calls out to one of his bear giants, Agrius, to get out his Pegasus, later revealed to be Blackjack, so he could hurry to Miami Airport. Realizing that Luke was after the fleece and wanted it to heal Kronos, Percy then tries his best by stalling Luke's chase after Clarisse, hopeful that if he stalls Luke's time, Clarisse would eventually reach camp in time.
To prevent Luke from chasing Clarisse, he asks Luke as to who the person was in the mysterious killing of Thalia's tree. Luke, not knowing that Percy was stalling him in a secret trap, answers the question honestly blurting out that he was the perpetrator that made Thalia's tree poisoned. Percy secretly then asked him the same question again and over more than once. Once Percy realizes that Luke was the one who fed Thalia's tree poison, he pulls out his last gold drachma and tosses it at Luke who ducks. The drachma flies through the air past Luke and into the spray of water in Luke's cruise ship's swimming pool.
After it went into the spray, Percy prayed to the goddess Iris to allow the permission of the drachma and Iris complies, allowing Percy the advantage against Luke. Once he has the advantage over Luke, Percy keeps asking the same question several times which Luke gets upset that he keeps asking the question over and over again. However, Percy doesn't care about Luke's yapping and, shouts out that whatever Luke has done made everyone stupid. Then he shouts out that everyone else at camp including Mr. D has to hear Luke's confession which Iris allows the message to be heard. An Iris-message opens up and shows Dionysus and the whole camp eating. Percy tells Dionysus that "you heard the truth, Mr. D., Chiron wasn't the one who poisoned Thalia's tree." Dionysus relents and realizes that Percy was right so he banishes Tantalus back to Tartarus, just as he is about to get over his curse.
The prophecy is not mentioned. Instead, they use the Great Prophecy.
The quest for the Golden Fleece in the book The Sea of Monsters is a reference to the original Jason, whom quested after the Golden Fleece with his team of heroes, the Argonauts, who were named after their ship (the Argo). The quest was started by the inclination of Pelias, king of Iolcus, after Pelias claiming the only way he would give his throne to Jason, who was the rightful owner, if he could menage to find the fleece and bring it to him. Also, the Odyssey is mentioned, with Annabeth mentioning Odysseus, the main antagonist being Polyphemus the Cyclops, Percy and Annabeth fighting Circe, and Annabeth wanting to listen to the Sirens.
