62 parts Complete Severus Snape and his younger sister Sabrina have a miserable childhood, growing up with their abusive father, and a mother too afraid to stand up to her own husband.
Even though her brother doesn't mind being a Slytherin like their mother, and joining the Death Eaters, Sabrina wants a different life, a better one.
She is determined to be good, but when she falls for Regulus Black, she realises that being good isn't quite as easy as she had hoped, and staying away from Lord Voldemort proves to be almost impossible.
