Fire and ash

Elena Alba, a girl from a well known and powerful family, yet the last living one. Her parents were killed and tortured by Voldemort when he attacked the witches and wizards in Romania. Her blood was something Voldemort craved and he never stopped until he got what he wanted and Elena was everything he wanted, her blood, her power, everything he needed. Yet she planned the same, she was going to kill him and his son. Elena was a former Dumstrang student but when she was fostered by a family in England, she had to move and attend Hogwarts, the same school Mattheo Riddle was at, all she had to do was kill him and then his father. Although along the way she discovered a lot of things, things that changed her forever.
