The Burning Maze (The Trials of Apollo)

The formerly glorious god Apollo, cast down to earth in punishment by Zeus as an awkward mortal teenager named Lester Papadopoulos, must restore five Oracles that have gone dark. Duty-bound to a confounding young daughter of Demeter named Meg, Lester managed to survive his first two trials. Now he and Meg must go through the Labyrinth to find the third emperor -- and an Oracle who speaks in word puzzles -- somewhere in the American Southwest.
