Clarisse La Rue, the daughter of Ares and longtime enemy of Percy, is given the quest to go into the Sea of Monsters to find the Golden Fleece. Percy and Annabeth decide to go also, not just for the Golden Fleece, but for their friend Grover, who is trapped in Polyphemus's cave. Tyson, Percy, and Annabeth, after saving Camp Half-Blood from two fire-breathing bulls, set out to find Polyphemus, who believes that Grover is a female cyclops and not a satyr.
