The god Apollo, cast down to earth and trapped in the form of a gawky teenage boy as punishment, must set off on the second of his harrowing (and hilarious) trials.
He and his companions seek the ancient oracles - restoring them is the only way for Apollo to reclaim his place on Mount Olympus - but this is easier said than done.
Somewhere in the American Midwest is a haunted cave that may hold answers for Apollo in his quest to become a god again . . . if it doesn't kill him or drive him insane first. Standing in Apollo's way is the second member of the evil Triumvirate - a Roman emperor whose love of bloodshed and spectacle makes even Nero look tame.
To survive the encounter, Apollo will need the help of a now-mortal goddess, a bronze dragon, and some familiar demigod faces from Camp Half-Blood. With them by his side, can Apollo face down the greatest challenge of his four thousand years of existence?
