Battle of the Labyrinth

This was an exciting book. Percy has to start at a new school, yet again. He goes for orientation hoping that nothing bad will happen this year, so that he can keep attending the same school for once, but of course, things quickly go crazy. He meets some crazy cheerleaders who try to eat him and nearly blows up the whole school before he can escape. This is a really fun series, I totally recommend it, and not just for kids!
