Neville's Law of Transmutation After Transfiguration

This story is fairly dark and not kind to Magical Britain. Harry is an abused child who used magic to 'hide' and does not trust adults. He is sorted into Hufflepuff and keeps his own counsel. He knows the only way to keep a secret is to not tell anyone. But he makes true friends in Hufflepuff, learns to trust some people. But first he must survive the dangers at Hogwarts.
