Who's Raven?

Ember was an ordinary girl, that was until she died and got reincarnated. At the age of 8 Raven got kicked out the orphanage for her freakishness and had to survive on her own, until a Hogwarts letter comes and she realises that she got reincarnated into harry potter. Wait the year is 1971! Dumbledore is not pleased that someone is messing up his master plan. OC. Self-Insert.
