With a book called 'Keeping Score,' I really did want to write a book about the Korean War, because I felt that it is the least understood war in the American cultural imagination. So I set out with the idea that Americans didn't know much about the Korean War and that I was going to try to fix a tiny bit of that.

What I like most: Reading well-written sources that take me to another world for hours at a time - and being able to call that work! Also, of course, finding a gem of information that is either exactly what I was looking for, or else fits perfectly into the story in some way.

I can give advice to anyone interested in writing in one word: Read! I think it's much more important to be a reader than to be a writer!

If a man is keeping an idea to himself, and that idea is taken by stealth or trickery-I say it is stealing. But once a man has revealed his idea to others, it is no longer his alone. It belongs to the world.

Most writers adore their editors, and I'm no exception.

I want all my books to provoke some kind of response in the reader, to make them think something or feel something or both, and for that to become a part of them and work into their own lives.

Each of my books has taken me a different length of time to write - eight months for Seesaw Girl, eight months for Shard, three years for When My Name Was Keoko! The publisher takes another year and a half to work on the book, so altogether each book can take up to three or four years to publish.
