Percy Jackson and the Battle of the Labyrinth (Book 4)/Rick Riordan

The fourth incredible adventure in the most exciting and commercial fantasy-adventure series since Artemis Fowl. Half Boy. Half God. ALL Hero. 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 - and now my arch enemy Luke wants 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.
