Lovely. Just... Lovely

A 14 year old girl, Valentina, born a Valentines day, wishes for a new life all together, on her favorite flower, a Lily. As her father is missing, and her mother has an alcohol addiction. When she wakes up the next morning, a mysterious man kidnaps her and takes her to an odd manor. When she wakes up, she's in a room and is greeted by a well-known, rich, pure, wizarding family, which it turns out, she's a witch. They alter her appearance to look like part of the family, and she chooses to have the same hair as her new family, bleach blonde. They treat her well and care for her, but they keep her forming going out unless going to Hogwarts, and is to be at home during all the breaks no exception. She got her wish, but something was wrong with this family. She's never aloud in the drawing room, the boys always wear long sleeves, and she's not aloud to know who her new brothers aunt is. But why?
