I'm a private person, a shy person. Sometimes, reading for eleven hours straight feels to me like the perfect way to spend a day.

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.

I feel like in American fiction we're moving out of a period of intense irony, and I'm very glad about that. I feel like irony is fine for its own sake but shouldn't be the sole reason to write a book. It has been an ironic world view: that's the best way I can describe it. I'm a fan of earnestness. I feel like there's a new wave of earnestness and I'd be happy if I'm some small part of that.

Fiction is always a utopian task, in that there's an ideal you hold in your head as you write which inevitably fails in the moment of creation, in the insufficiency of words to convey meaning, or in the way the work is completed in the reader's head.

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.

Who, in the midst of passion, is vigilant against illness? Who listens to the reports of recently decimated populations in Spain, India, Bora Bora, when new lips, tongues and poems fill the world?

The darkest period of my life, so far, arrived the summer I was pregnant with my eldest son. The future was growing in me with all of its terrifying unpredictability, and I found myself anxious, unable to work and woefully at sea.
