The third book in the breathtaking mythical series about gods and heroes, from the international bestselling author Rick Riordan.

Five ancient prophecies. One very grumpy ex-god.

He was a God once. Until he was cast out his father, Zeus. Now, he's an awkward teenager. Called Lester.

The only way out is a series of scary and dangerous trials, of course.

For his third trial, Apollo must journey through the Labyrinth to free an Oracle who only speaks in puzzles.
Then, defeat the most vicious of three very vicious Roman Emperors.
(All without the use of his godly powers.)

It looks like he will need all the help he can get - from some new and old friends.
