A year after Gaea's Awakening, Nico di Angelo is chosen to lead a quest to Britain in order to find Tom Riddle, a man who has defied Hades and cheated death twice. With Percy and Annabeth accompanying him, Nico must find and destroy seven horcruxes, navigate through his fifth year at Hogwarts, and deal with his own problems back at Camp Half-Blood, all while hiding the fact that he's a demigod from all the wizards in England. Between a budding romance with a certain son of Apollo, a burning desire to make his father proud, and an old vow against killing mortals, the son of Hades is going to do whatever it takes to outwit the Fates and succeed... or die trying.

All Nico wanted was a quiet, mortal life and a high school diploma. But when a shaky peace between Hades and Demeter finally snaps, he's forced on a quest with no prophecy that quickly spirals out of control. Tensions rise until they threaten to turn into all-out war among the gods. And in the wake of Voldemort's death and a massive Ministry cover-up, the Wizarding World falls into anarchy. Ron, Hermione, and Cho are thrown into the world of the gods as they set out to save their home before it collapses completely. How can you fight when there's no enemy in sight? How can you be free when fate itself has turned against you? There's nowhere to run, nowhere to hide. Not when all of Western Civilization is on the line.
