Cassie Black (Sirius Black Sister)

My brother once told me that I would one day hate myself for leaving and that is partly true. I mean what type of sister was I if I left home and never looked back without so much of a guilty thought. I would be exactly the same as him the hypocritical git. When I was five years old my brother left home well more like ran away and went to live with his best friend. Leaving me the innocent baby sister to the darkness of my parent's teachings. I grew up believing that muggles were dirty and the only way was pureblood. Until one day when I was ten I bumped into the same person who left me in a coffee shop.
