I sometimes have to write for a while before I figure it out, pretend that I know what I'm doing, sort of like ad-libbing on stage until you remember your line - you hope you sound convincing to the audience. The key is to have enough material, enough threads, so that there's something that can be satisfyingly drawn to a conclusion.

I liked the push and pull of that, between the outer political world and the inner personal lives of the characters. It's also real life... Many of us are keenly aware of world events, but break your nose and I bet that's the main thing you'd be focused on.

[Ending] is partly drawn from a desire to shock the audience, to brutally de-romanticize what many Americans think is happening overseas. And partly drawn from my own childhood: violence and a loss of innocence. But keep in mind that, as a writer, I'm both the criminal and the victim. I'm not trying to get out of anything easy.

I don't feel any ethical dilemma when I write. In my memoir, I was able to write with candor about the two most difficult people in the world to write with candor about - mom and dad. Everything else is downhill from there.

When the ending finally comes to me, I often have to backtrack and make the beginning point towards that ending. Other times, I know exactly what the ending will be before I begin, like with the story "A Brief Encounter With the Enemy." It was all about the ending - that's what motivated me.

An initial impulse of mine was to portray the way in which a city is impacted by war. But this is vague, no? After all, how do you actually have an entire city - or country, for that matter - be a character a reader can follow? One way is by making it smaller and personalizing it, by writing specifically about the citizens and the way they contend with the reality, even minutiae, especially minutiae, of their lives.
