Siblings Sadie and Carter Kane discover that the gods of Egypt are waking, and the worst of them–Set–has his sights on them. to Stop him

Will the Greek god Apollo, cast down to earth in the pathetic mortal form of a teenager named Lester Papadopoulos, finally regain his place on Mount Olympus?
Lester’s demigod friends at Camp Jupiter just helped him survive attacks from bloodthirsty ghouls, an evil Roman king and his army of the undead, and the lethal emperors Caligula and Commodus. Now the former god and his demigod master Meg must follow a prophecy uncovered by Ella the harpy. Lester’s final challenge will be at the Tower of Nero, back in New York.

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.
Somewhere in the American Midwest, he and his companions must find the most dangerous Oracle from ancient times: 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.

Jason has a problem. He doesn’t remember anything before waking up on a school bus holding hands with a girl. Apparently she’s his girlfriend Piper, his best friend is a kid named Leo, and they’re all students in the Wilderness School, a boarding school for “bad kids.” What he did to end up here, Jason has no idea—except that everything seems very wrong.

He’s b-a-a-ack! Despite their best efforts, Carter and Sadie Kane can’t seem to keep Apophis, the chaos snake, down. Now Apophis is threatening to plunge the world into eternal darkness, and the Kanes are faced with the impossible task of having to destroy him once and for all. Unfortunately, the magicians of the House of Life are on the brink of civil war, the gods are divided, and the young initiates of Brooklyn House stand almost alone against the forces of chaos. The Kanes’ only hope is an ancient spell that might turn the serpent’s own shadow into a weapon, but the magic has been lost for a millennia. To find the answer they need, the Kanes must rely on the murderous ghost of a powerful magician who might be able to lead them to the serpent’s shadow . . . or might lead them to their deaths in the depths of the underworld.

Since their mother’s death, Carter and Sadie have become near strangers. While Sadie has lived with her grandparents in London, her brother has traveled the world with their father, the brilliant Egyptologist, Dr. Julius Kane.
