I do like Twitter. Writing is a solitary pursuit, and it can get lonely. I like to go into Twitter for a short period of time, communicate with clever friends, and then switch it off. That's perfect for me.

Freedom or community, community or freedom. One must decide the way one wants to live. I chose community.

As with most of my work, I started from the abstract, from research, building an intellectual model that slowly became internalized when the characters came alive. It's fascinating what happens to the model you've so assiduously assembled when characters are allowed to run rampant: things you thought essential are broken and other things are vastly improved.

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.

Parenthood means becoming comfortable with the fact that there are things outside your control, things that end and fail, just as most utopias end and by some measure fail. And just because they're a failure doesn't mean there isn't value there.

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.

Plays are just all sort of playful asides, and there's a great deal of reference here to Greek mythology, plays, and dramas. The idea of the chorus is really important in Greek drama and I loved the idea of including that.
