I write books about magic, gods and monsters (mostly). I wouldn’t rule out writing about spaceships or murders or spies, either. The only books I promise not to write are ones about people sitting around talking about their feelings. A few of my favourite books as a child were Lord of the Rings, Just William, a space epic called Halo Jones and a book about a vegetarian vampire called Vlad the Drac. I love comics of all kinds and fact books about space and the environment. I used to write fact books, but honestly it’s a lot of work, so I’ve just let the truth slide and I make things up now. You get complaint letters if you say Jupiter has the wrong number of moons in a fact book, which really isn’t fair, because they keep discovering new moons, the cheats. I live in London with my wife, our dog Buffy and a creepy puppet who has no name.
