I enjoy the research element. There are so many stories from the past that interest me, that I want to learn more about, just as an interested person. And if I'm going to learn, if I'm going to research, it's probably going to lead me to writing a novel.

War today is such a more visible thing. We see it on television, on CNN. In 1914, war was a concept.

I like reading books about kids where there weren't really many adults, where they didn't need an adult to come and solve the problems for them. They could use their own ingenuity, use their own talents to solve whatever the issue was. And I like that still. I think that children want to read about heroic children. They don't want to read about children that have to be saved all the time.

I was dropped by my publisher after my first two books. But I always believed in myself.

I hope for so much from every book I read. And time and again, I find myself disappointed. I look across my bookshelves and see hundreds of titles which in my memory seem merely mediocre or second-rate. Only occasionally does a novel appear for which I feel a lasting passion, a book that I think could in time become a classic.

Unless you're very boring, I think most people who've lived long enough have something in their past which will never go away. As a writer, my interest has become in writing about much more emotional, personal topics. I'm trying to reach into subjects I have never written about before.

I think that books for young people should have serious and important themes, they shouldn't be trivial. So the books I write, they would be the kind of stories you would write in an adult novel only they just happen to feature a child at the center of them.
