Harry has a sister named Violet Potter, who has a dark secret that she doesn't want anyone to know. No one has ever heard of her existence to this day because she has worked so hard to keep herself and her past hidden. But when she goes to Hogwarts and meets Severus Snape, how can she keep her secret when she realizes she's in love with the potions master? Shocking truths about the past and future will be revealed that were probably better off left unknown. When a dangerous force seeks to destroy the universe, can Violet Potter stop it before it destroys all of reality? Obviously, all characters and the original story belong to Jk Rowling, except for Violet Potter, who is my own creation.
