Hermione Granger and the Hostile Decision

Peggy Sue gone horribly wrong. Hermione goes to the Room of Requirement after the Battle of Hogwarts. Waking up, she finds herself eleven years old again. Easy this time, surely, if she can alter the timeline? Except she ends up being kidnapped off the Hogwarts Express and in the hands of a terrifying wizard. The next seven years don't look easy, but will she be able to survive?
