My name is Remus John Lupin. I am 11 years old. I go to Hogwarts School of Witchcraft and Wizardry and I'm in Gryffindor. My dad died when I was 7. My mum is great, but I wish she wasn't alone now. My sister, Renoir, is 18 - she finished Hogwarts last year, and she works at Gringotts in London. I like school, but I'm always scared that people will find out my secret, because if they do, they won't like me any more.
