The Coming of Nico di Angelo

Three demigods shall travel to the followers of Hecate,
The monster inside lets the dark one blood see,
On the brink of destruction, Poseidon and Athena unite,
The father of blackness has a great insight,
The friend is an enemy, the enemy a friend,
Against a weak but powerful army, the child must reveal his true self in the end...

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.
