Ruth Williss- The Muggle

Ruth Williss. Muggle. SHe had to watch her mother walk out of her life at age 9. Watch her dad die at age 10. Watch her sisters get adopted while she was left alone. She never understood why people left her. But didnt care. The abusive caretaker at the Orphanage was her main problem. She couldnt tell her sisters because one was too busy being at Hogwarts. And the other was too young to know. So now, at age 16, after lifing 3 years in hell with a abusive gardian, She receives a letter. A letter from her eldest sister, Cat, Who is asking her to come to Hogwarts to sapport her while she is a champion in the Triwizard Tornament.
She agrees.
Meeting the marauders was easy. But when her new best friend Lily takes a secret liking to James, Everything goes down hill. Secrets are spilled, Lies are made, Promises are broken, and when everything seems appart, Ruth can only think of one thing: They always leave.
So will Sirius stay?
