Two Worlds Combined (Percy Jackson and Harry Potter Crossover)

Amber Whitney has had a crazy year. Voldemort and his Death Eaters rose to power, killed countless innocent people, and had only recently just been defeated. She was ready to go the only other place where she belonged: Camp Half-Blood. Though she'll miss all of her friends, and especially her boyfriend, George Weasley, she wanted a nice, peaceful summer at camp, away from Hogwarts and the rest of the recovering wizard world. That was apparently not going to happen according to the Fates.

Before her wizard friends found her at Camp Half-Blood, they hadn't known about the other side to her, the godly side. Amber wasn't like normal half-blood wizards. Her other half wasn't human, it was god. Her mother was Hecate, Greek goddess of magic. And now the wizards knew the secret she had been forced to keep from them, only able to tell the activities director at Camp Half-Blood, Chiron; the head of Gryffindor House, Professor McGonagoll; and her late Headmaster, Professor Dumbledore. And, well, he had taken her secret to the grave.

But now a new enemy was rising. One like her: half wizard, half god. And he was trying to bring back her three most powerful enemies: Kronos, the Titan Lord; Gaea, Mother Earth; and Voldermort, the most evil wizard who everyone had thought was done for. Can Amber unite the demigods and wizards so they can stop these enemies from rising before it is too late?
