Harry Potter and The Unabusive Childhood
A retelling of Harry Potter and the Philosopher's Stone where Regulus lives, and so too does James Potter.
Harry is raised far away from the world, sequestered in a little home of warmth, of safety, of peace and truth. Very few people know him even alive, seeing as he disappeared after the death of his mother.
His debut at Hogwarts is even more shocking then, when the son of James Potter and Lily Evans is sorted into Slytherin.
A ward of the snake house, thrown into chaos of life after the quiet of his upbringing, utterly alone in that large castle with a Headmaster who seems to trace his every move, follow the Boy-Who-Lived through his first year of Hogwarts.
