I want the flashbacks to feel that once you're there they have their own unity, their own kind of atmospheric sensibility; I want the reader to be transported. The novel is a big, complicated, unknowable thing before it's written.

I really try to forget. I only look at my old works if there's an interview and someone asks me about it. Otherwise, it's not even in the rearview mirror.

I did a lot of reading of first person accounts from Koreans and combatants and aid workers. And I spoke to relatives. A lot of wonderful photographs were made available to me from that period - 1950-1956 - and those were given to me by a Korean newspaper in Seoul. Ruined villages, refugees streaming through a river valley, GI's and orphans and orphanages, those tiny details that you can only see in a picture.

Like most people, Im fascinated by characters who are completely flawed personalities, riven by anguish and doubt, and are psychologically suspect.

I had a visceral connection to the period [of Korean War]. By visceral I suppose I mean emotional. But every fiction requires so much that is not that so I did a lot of other research and a lot of thinking, a lot of struggling there.

I'm more interested in the psychic intricacies that they build up and try to run away from, and how they self-construct. A lot of my work is about self-construction. Here, it's those folks who are deeply wounded and bewildered. They're not just victims of trauma; they've been shaken so forcefully that they don't quite know how or where to stand.

We can skip through a lot of the stuff people might ask about the writing of the book, and so their comments always start well, well down into the nitty-gritty.
