There are no taboos. Every topic is open, however shocking. It is the way that the topics are handled that's important, and that applies whether it is a 15-year-old who is reading your book or someone who is 55.

I use a lot of similes and metaphors when I work, simply because it's my best way of describing a building or a scene. I'm terrible at describing landscapes - trees, buildings.

Kids tell me all the time, "I don't know how you do it, but that's us in the book." That's the kind of response you want, and I can't sacrifice it for the sake of somebody worried about censorship. You have to find a way to be truthful and honest.
