Percy Jackson's seventh-grade year has been surprisingly quiet. Not a single monster has set foot on his New York prep-school campus. But when an innocent game of dodgeball among Percy and his classmates turns into a death match against an ugly gang of cannibal giants, things get... well, ugly. And the unexpected arrival of his friend Annabeth brings more bad news: the magical borders that protect Camp Half-Blood have been poisoned by a mysterious enemy, and unless a cure is found, the only safe haven for demigods will be destroyed.
In this fresh, funny and wildly popular follow-up to "The Lightning Thief", Percy and his friends must journey into the Sea of Monsters to save their camp. But first, Percy will discover a stunning new secret about his family - one that makes him question whether being claimed as Poseidon's son is an honor or simply a cruel joke.
"In a feat worthy of his heroic subjects, Riordan crafts a sequel stronger than his compelling debut." - Publishers Weekly (starred review)
"A fast and funny tale, full of action, wisecracks, and superhuman powers." - KLIATT (starred review)
