Leaving the safety of the demigod training ground, a disgraced Apollo embarks on a quest across North America to find a dangerous ancient-world Oracle while navigating the challenges of the evil Triumvirate.

"The six spheres to pronounce judgment, the six spheres to wield its power, the six spheres to resurrect the demon, and in death . . . rule in darkness..." In the fires of the Dark Lands in the midst of war, a prophecy will be born entrusted with an immense task. He must fulfil the prophecy of the gods and become who he was born to be, the one who will bring an end to evil. Deep within the pit of evil a shadow is unleashed from its shackles, and plots to wreck total chaos on Middle Earth, and become the Lord of the Six Spheres of Power.

In accordance with prophecy, Avalon's existence is threatened in the year that stars stop shining and at the time when both the dark child and Merlin's heir are to be revealed.

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, and restoring them is the only way for Apollo to reclaim his place on Mount Olympus - but this is easier said than done. Standing in Apollo's way is the second member of the evil Triumvirate - a Roman emperor with a love of bloodshed and spectacle. 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?

Zeus has punished his son Apollo--god of the sun, music, archery, poetry, and more--by casting him down to earth in the form of a gawky, acne-covered sixteen-year-old mortal named Lester. The only way Apollo can reclaim his rightful place on Mount Olympus is by restoring several Oracles that have gone dark. What is affecting the Oracles, and how can Apollo/Lester do anything about them without his powers? After experiencing a series of dangerous--and frankly, humiliating--trials at Camp Half-Blood, Lester must now leave the relative safety of the demigod training ground and embark on a hair-raising journey across North America. Fortunately, what he lacks in godly graces he's gaining in new friendships--with heroes who will be very familiar to fans of the Percy Jackson and the Olympians and Heroes of Olympus series. Come along for what promises to be a harrowing, hilarious, and haiku-filled ride. . . .

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.
