With enemy ships sailing his waters and setting fire to his cities, and the sinister Tanner Black threatening to steal the throne before Drake even has a chance to sit upon it, Drake Morass must somehow convince the other Captains that his best interests are also theirs.
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.
After his role in the events in the Heroes of Olympus, Apollo has been turned in a 16-year-old human boy by Zeus and must serve the first demigod that enlists his service until his father has deemed him worthy to re-join Olympus.
How can a handful of young demigods hope to persevere against Gaea's army of powerful giants? As dangerous as it is to head to Athens, they have no other option. They have sacrificed too much already. And if Gaea wakes, it is game over.
They have no choice. If the demigods don’t succeed, Gaea’s armies will never die. They have no time. In about a month, the Romans will march on Camp Half-Blood. The stakes are higher than ever in this adventure that dives into the depths of Tartarus.
