Harry Potter: Fire Lord Black

The Black heir did not grow up in the magical world. He had no name, no family, and no past. Only fire. Edward grew up nameless in the Muggle world, surviving on scraps, cold streets, and a strange flame that never burned him. When Hogwarts finds him, he discovers the truth: he is Edward Black, the lost son of Regulus Black. He does not know what kind of wizard he will become, but one thing is certain, no one will ever erase his flames. — Description from novelcodex.org
