In terms of writing, I think what most fiction writers treasure more than anything is the feeling that they're living for the length of a book inside another person.

Reading about utopianism, and eventually creating characters with their own utopian ambitions, was the way I learned to live with being a pregnant person, to stave off the sense of incipient disaster. You're bringing a person into this overcrowded world, knowing they're one day going to die and there's nothing you can do about it.

I love writing from enclosed spaces: you really learn about your characters when they have tight walls to push against.

The idea of legitimacy is something I suppose I deal with in my fiction, and in part it's probably a response to my upbringing. When I was growing up I was the middle child, pathologically shy, in a family with a very loud and opinionated older brother, and I felt as if I never had the right to speak. As a result, I simply didn't speak very much.

I can say that if you're a writer who happens to be a woman, you'll get a book cover that depicts a woman with no head, or a woman turning away, or a pair of high heels. You have to fight to not get stuck with these covers. In the U.S. women are chick-lit writers unless they prove otherwise, and that's frustrating.

I'm an anxious person in general, but something about being pregnant and awaiting the release of my first book, The Monsters Of Templeton, made me into an insane anxious person. I didn't sleep at night. I ended up sleeping all day. In a strange way I felt like the world was going to end. I found myself so deeply depressed at times that I started to read about happiness, and that took me into books about idealism and utopianism. Reading books about people who tried to build utopian societies of different kinds gave me a kind of lift.

I'm ambivalent about the Orange Prize. I was really proud to be shortlisted alongside the other writers, whom I admire. That said, I don't know if it's best way of addressing gender inequality problems.
