Percy Jackson and the Olympians book 2 of 7 ongoing series

Percy Jackson's seventh-grade year has been surprisingly quiet. Not a single monster has set foor 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.
