Summary
Post-Deathly Hallows, a very different Hermione Granger returns to Hogwarts to complete her last year of magical study, haunted by wisps of memories and ghosts long dead. A certain dark and malicious Potions Master happens to notice. Throw in a little meddling from everybody's favorite white-bearded wizard, and you've got a recipe for firecrackers. And, perhaps, something more.
