Her Ancestors

A girl who never knew her parents was given to her aunt by her mother and was told to never tell her what she was. Her aunt kept what she was a secret until she was 13 when her aunt forgot to hide the letter she gets from Hogwarts for the third year and she finds it. Her aunt has no choice but to tell her and that's when her journey begins. (I do not own Harry potter or the characters. Story is by me.)
