I loved short stories, and they were all I wanted to write. I love the compression of them and the exactitude needed to get a whole world into such a small space.

That requires quite an imaginative leap because it's hard for me to imagine that my biography would be of much interest to anyone, and because I'm a fairly private person, the notion doesn't appeal to me.

If you had told me twenty years ago that I would write a novel set in Russia, much less two, I simply wouldn't have believed you. I had no familiarity with Russia or its history, but part of what drives me as a reader, and more and more as a writer, is curiosity, the desire to explore unfamiliar terrain and inhabit alternate lives.

Peculiar as I was, and remain, I was trained to be practical. I'm still amazed at the radical temerity of my friends, you included, Julie, who choose poetry as their vocation. I envy your faith.

I always think, OK, this is good, but I'll do it better next time. "And so we beat on, boats against the current. . ." It may not be the recipe for a life of contentment, but that imperfectability is what makes writing such an engaging endeavor, something you can do for the rest of your life and not get bored.

I tell my students, if you're interested in marine biology or llama farming, follow that string. Yes, it will probably take you a longer time to write that book, but it's not a race. That's another great thing about being a writer: you don't age out.

With the historical fictions, I was already doing so much research, and so much of the stories was anchored by historical truth that the move to nonfiction didn't feel all that dramatic - just another half-step to the right.
