Voldemort's Child

There's a new boy at Hogwarts - Kione Gaunt, who bears an uncanny resemblance to the late Potter family. Rumor has it that he's the Dark Lord's son, his most devoted and most dangerous follower. According to the Prophecy, he might also be the only one who can save the world from Voldemort's unending reign of tyranny and terror. Dark!Harry.
