Percy Jackson and the Sea of Monsters

Percy is back at Camp Half-Blood — and something is very wrong. Thalia’s tree, which protects the camp’s magical borders, has been poisoned. The borders are failing. Monsters are getting through. And the only thing that can save the camp is the Golden Fleece, somewhere in the Sea of Monsters — which is to say, the Bermuda Triangle — guarded by a Cyclops named Polyphemus.

The second Percy Jackson novel is faster and more confident than its predecessor, and introduces one of the series’ most beloved characters: Tyson, Percy’s Cyclops half-brother, whose combination of enormous strength, complete guilelessness, and total devotion to Percy makes him immediately irresistible. Riordan uses the Odysseus parallel — Circe, the Sirens, the Cyclops — with a wit and a lightness that makes it feel fresh rather than derivative.

A perfect adventure novel for young readers, and a series that genuinely rewards the investment of following it through all five books. Published by Puffin.
