A Difficult Journey
The Greek god Hermes gives to Percy; Annabeth, Percy's demigod best friend; and Tyson, Percy's cyclops half-brother, hippocampi -- horses with fish tails -- to help them get to a cruise ship that will supposedly take them to the Sea of Monsters. Conflict arises when they discover that the ship's captain is evil, so they must escape on a raft. They meet up with another demigod, Clarisse, who takes them to the Sea of Monsters on her battleship. Trouble presents itself again as Percy and his companions must defeat monsters and an evil sorceress. The hippocampi return and take them back to Camp Half-Blood, but first they must navigate one final conflict -- a battle with Luke, an evil former camp counselor. Percy and his friends discover that Luke is responsible for poisoning the tree, but the Golden Fleece eradicates the poison.
