The Battle of the Labyrinth (Percy Jackson and the Olympians #4)(Paperback Edition)
by Rick Riordan
Goodreads Rating: 4.39
Publisher: Puffin Books
Freshman orientation is about mastering new things, but this is ridiculous. Percy didn't expect that in his first week at school, he would have to face a squad of demon cheerleaders. And the dangers are far more than scholastic: Kronos's armies are threatening even the relative safety of Camp Half-Blood. The fourth installment of Percy Jackson and the Olympians deals out action, surprises, suspense, and gripping characters.
