I got tired of books where the boy is a bit thick and the girl's very clever. Why does it have to such an opposition? Why can't they be like the girls and boys that I know personally, who are equally funny and equally cross? Who get things equally wrong and are equally brave? And make the same mistakes?

I try to avoid describing one interpretation of my books. Of course I have an opinion. I have things I want to say, but I don't ever want to limit anybody, to have them say, 'Oh, he said this, so that's what it's about.' I'm happy people bring their own stuff to it.

If you sing beautifully about nothing, no one will listen. If you sing badly about great stuff, no one will listen. Ideas are everywhere, but my theory is that a writer doesn't just think of an idea: they perform them.

For me, when I start a novel, I only have a general sense of what I am going to do - usually three or four big scenes or something to which I can really respond emotionally.

Anything that anybody wants to give me is great! I've had folk songs, heavy metal songs, jewellery... I would never call anything any fan gives me weird, as it's how people express what they like about the books, what it means to them, and that's a wonderful thing.
