The Half-Blood Princess

Margret Severus Hobblepot was a 13 year old homeless girl who had no place to go, no one who loved her and no family to speak of. There just one thing this poor little girl doesn't know yet and that she's a witch. How will she handle being taken to Hogwarts and being around other people? How will she handle being given a teacher as a parent and when that teacher is hated by most people in the school. But most of all how will she feel when she finds out that said teacher really was her parent and will she ever learn how to talk again?
