Percy Jackson 2 - The Sea Of Monsters - Riordan... Link

Percy, Annabeth, and Tyson (Percy’s newly revealed cyclops half-brother) sneak out with Clarisse (Ares’ daughter) to find the Fleece before Luke does. They survive Circe’s spa (Percy gets turned into a guinea pig), the Sirens (Annabeth is tempted), and Scylla & Charybdis. They retrieve the Fleece, but Luke escapes.
