Honestly, blowing up another school was the last thing I wanted to do. As the son of a Greek god, I've had my share of near-death disaster. This summer, I didn't choose to battle the cheerleading squad, but when two hissing she-devils with fangs are heading straight for you, what's a half-blood meant to do?

That was just the beginning. This is the one where my arch-enemy, Luke, is looking for a way to invade our camp via an ancient labyrinth. If he succeeds, thousands of bloodthirsty monsters will attack. So it's goodbye sunshine, hello darkness as four of us descend into the terrifying underground and beyond . . .

Percy Jackson and the Battle of the Labyrinth is the fourth title in the Percy Jackson series.
