When I was five, we moved to Virginia and lived inside an old fort that was surrounded by a moat. So when I heard stories of American history, I felt as if those dramas were taking place right in my own backyard.

I love reading all kinds of books. I usually have about ten books going at any one time - books about the past, the present, novels, non-fiction, poetry, mythology, religion, etc. Reading is my favorite thing to do.

I love using my imagination. I love writing about animals.

I get ideas from my own personal experiences, from my imagination, and from my research and from old stories.

I discovered writing children's books was a way to keep living in my imagination like a child. So I wrote a number of books before I started 'Magic Tree House.' Then, once I got that, I never looked back because I could be somewhere different in every single book.

My imagination is closer to a child's imagination than to a grown-up's.

A military childhood in the 1950s was very much informed by WWII. My brothers and I often heard stories from our dad - and from other kids - about things that had happened to their dads. We constantly played war games and, nearly every Saturday, saw a different WWII movie at the post theater.
