I had been a reporter for 15 years when I set out to write my first novel. I knew how to research an article or profile a subject - skills that I assumed would be useless when it came to fiction. It was from my imagination that the characters in my story would emerge.

[s]he was a compulsive pessimist, always looking for the soft brown spot in the fruit, pressing so hard she created it.

Work less than you think you should. It took me a while to realise there was a point each day when my creativity ran out and I was just producing words - usually lousy ones - for their own sake. And nap: it helps to refresh the brain, at least mine.

I wasn't sitting around years ago thinking I really want to write a novel.

So the premise of 'The Submission' is that there's an anonymous competition to design a 9/11 memorial and it's won by an American Muslim, an architect born and raised in Virginia, and his name is Mohammad Khan.

I think in the wake of 9/11, like a lot of Americans, you know, we were all very traumatized by the attacks, traumatized in a totally different way by some of what happened afterward in response. And I think there have been these questions hovering in the past decade of, what kind of country are we? Who are we?

And as journalists we look for differences - differences between countries, cultures, classes, and communities. We're very sensitized to difference, but it's much harder to write about similarities across countries, cultures, classes, and communities.
