The future is lost, so to save it, both Harry and Dumbledore go back the moment it all began - that Halloween night. Of course, things do not go exactly as they had expected. Unspeakables, Wild Magic, Time Travel, Vampires, Bonds, Goblins.

Harry Potter is 16 years old. He already defeated Voldemort, with the help of his Godfather Sirius Black. Now he is in for the biggest challenge of his life: attending Hogwarts School of Witchcraft and Wizardry.
