I'm a writer, not an actor. I want to write rather than perform. I'm looking forward to disappearing for a while.

There is part of me that longs to have the back-to-the-earth life - make my own bread, grow my own wheat, just be really self-sufficient - but I am not, at the moment, willing to give up the luxury of modern life, and amazing schools for my kids, and things that I've come to rely on that are parts of society.

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.

In the end, fiction is the craft of telling truth through lies.

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.

The trouble is that America's become a utopia accessible only to some people. Others get trampled on. Perhaps it's a problem of size. Robin Dunbar, an anthropologist, once gave the ideal number of a given community as 148. That seems about right to me. There's something idealistic about that - in a group of 148 people you can get to know everybody.

Our human impulse is to control everything, but fiction seems to me to be about allowing an element of mystery into the text.
