The Incantation of the Oak-Priest
A fifteen-year-old Tom Riddle slips through time, pulled by a scarred boy into a seemingly idyllic future. Harry Potter falls with him into a reality untouched by Voldemort's reign. Taken into the Potter household, the two form an unlikely bond – but between centaur magic, governmental plots, and the darkness at the heart of the Forbidden Forest, this new world is not as it seems.
(In which Tom learns to be kind, Harry learns to be cruel, and ancient magic sings to them both from the woods. Meanwhile, a war of metal and secrets brews in the shadows, threatening an end to the fragile peace.)
