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.

I rarely talk about work with writers, and I love getting together with writers. I think writers are great to get together with, because we can talk about everything. I think that's why I enjoy it. Writers tend to be pretty open-minded, and pretty profane and loose. They have fun minds.

Usually, when you're talking about work with other writers it's because something seriously bad is going on with your work and you've absolutely thrown out a lifeline and you're hoping that someone will help you with something. Either there's some bad feeling you have about the work, or sometimes it's not specific - just kind of solidarity.

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.

For if there is ever a moment when we are most vulnerable, it’s when we’re closest to the idea of the attained desire, and thus farthest from ourselves, which is when we’ll tread through any flame.

I did feel a little afraid, as you say, the complete liberty and "elasticity" of it. But I found that I liked some of the things that it availed me of in terms of emotion and tonal stuff. I came to find it appealing.

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