Daughter of Black

She was named after both her parents. On her father's side of the family, it was tradition that they were named after stars - Mira. Her mother's name was Arabella so her father gave her part of her mother's name as well. He wanted part of both of them in their daughter - Bella.
Mirabella Black.
Daughter of two great wizards. Godsister to Harry Potter - the boy who lived. She wasn't who everyone wanted her to be. To everyone else she was the daughter of a murderer, family to the chosen one, the girl destined to end up like her father - in prison - or like her mother - dead.
She chose her own path. And along the way she became the girl who loved. The girl who loved her best friend more than anyone else. The girl who fell in love with George Weasley.
