For at some point, each of us will be asked to embody what we feel and know.

For no matter the shadows of an age, the picture of a young couple in love, we are told, speaks most luminously of the future, as the span of that passion makes us believe we can overleap any walls, obliterate whatever obstacles.

Obviously loss of family is huge and critical, but I think really it's more about losing a sense of family. The horror of that kind of incompleteness. Writing this book, I tried not to think about my father, which does no one any good fictionally. I did try to imagine not just the horror of that moment, but the horror of having witnessed it, and the lifelong void. And I think that's what's so frightening.

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.

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.

When I'm describing wartime activities or violence I don't want to be too ornate, to prettify the picture. Once we trace them to the present, the prose becomes denser.

It's just a weird idea to me because each book is a complete universe unto itself, so why would I want this other universe from this other galaxy that has nothing to do with mine? That's how I really feel about it. Let's be honest - I'm still the writer, so certain things will be common denominators. But that I just want to keep natural and not studied.
