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.

And it occurred to me that in this new millennial life of instant and ubiquitous connection, you don't in fact communicate so much as leave messages for one another, these odd improvisational performances, often sorry bits and samplings of ourselves that can't help but seem out of context. And then when you do finally reach someone, everyone's so out of practice or too hopeful or else embittered that you wonder if it would be better not to attempt contact at all.

I wanted to write about the Korean War, but I had no entry into it that made the kind of sense it needs to make for a novelist.

It's not that I don't enjoy other people, but what I find with writers is this back and forth. And also, there's no need to talk about work.

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.

It's not that I wrote those details, but photos can give you the confidence that you have a real feel for the landscape. Then you can invent with a solid kind of faith, and recreate a feel and flavor of the time, and, one hopes, a tonality, a sense of that time having been lived by those characters.

I'd always wanted to write something about the Korean War because of my heritage. My father lost his brother during the war, and I fictionalized that episode, which was told to me very briefly without much detail.
