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 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 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.
