Sea of Monsters

Percy Jackson's school year ends abruptly when a game of dodgeball turns out to be infested with cannibals. Then he finds out that a Cyclops named Tyson is his half-brother. And that the magical tree that protects Camp Half-Blood has been poisoned, which means that none of the demigod campers are safe. And that his best friend, the satyr Grover, has been kidnapped and taken to an island in the Bermuda Triangle—the sea of monsters.

But the island is the home of the famous Golden Fleece, the only thing that can cure the poisoned tree and restore safety to Camp Half-Blood. With the help of a hip and stylish jogger (who is, of course, the god Hermes), Percy, Tyson, and Annabeth set out on a Jason-and-the-Argonauts-style quest to rescue Grover and save Camp Half-Blood.
