Remus Lupin and Gryffindor's Old Hat

Remus Lupin thinks he is anything but an ordinary wizard. He hates the smell of blood but eats his meat raw, he's covered in deep scars, his father keeps a loaded muggle gun above his bed and he'll never go to Hogwarts School of Witchcraft and Wizardry. The Reason? Remus Lupin is a werewolf! The first part of seven years of the Marauders at school.
