Hermione's Amnesia

A backfiring spell forces Hermione to forget everything about her life and herself, and she wakes up in a strange house with people who want her to start to new life as someone different. After escaping the house, Hermione goes on a quest to try to find the mysterious 'Hogwarts' that her brain keeps reminding her of. Who was she and who was Harry Potter? I don't own any of this.
