The third title in Rick Riordan's Trials of Apollo series - set in the action-packed (and hilarious) world of Percy Jackson Lester Papadopoulos was once the glorious god Apollo, Now he's an awkward (mortal) teenager, stuck on earth without his powers. The way out? A series of scary and dangerous trials, of course. With two particularly scary and dangerous trial already under his belt, Lester must now journey to the Labyrinth - a burning maze with an Oracle at its centre, who may just hold the key to a return to godly glory. But The Labyrinth holds a far more deadly threat - the third Roman emperor, part of a group of three, all bent on death and destruction. The mortal and immortal worlds won't be safe whilst they live, and only Lester and his demigod friends have the power, bravery (and luck) to stop them . . .
