I write all over the house. Because I write in longhand, I can go anywhere I want... I have some notebooks here and there, and then I type it in and pull it out, and I do the revisions all over the place.

I think the plasticity of the novel is its greatest challenge. There are no rules; there is no necessary form. You can know what you want it to be, or do, and still not know how to write it. There are endless possibilities, infinite choices. What voice should it be in? What events to start with? What characters will be part of it?

I think I'm less disciplined than a lot of other people, I'm afraid, but on the other hand, I've written a lot of books.

I was struck after 9/11 by what seemed the assumption that everyone bereaved by that event was suffering the same thing. I wanted to explore how individual grief is, how complicated, how colored by the complexity of the mourner's relationship with the person who's died.
