I am frustrated by celebrities who decide to write children's books because they think it's easy. That drives me crazy. It's frustrating because it's unfair to children. Because they'll get a lot of attention, they'll get a lot of marketing budget and so on just because they're a celebrity - the Madonnas, the Ricky Gervaises, the Russell Brands.

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.

Well you've been brought here against your will, just like I have. If you ask me, we're all in the same boat. And it's leaking.

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.

War today is such a more visible thing. We see it on television, on CNN. In 1914, war was a concept. There was a naivety and stupidity that war would be a great lark. It's not that different from Gone With The Wind, where all the young men can't wait to go off to fight and then two hours later in the movie, we see how the reality of that has come home to them.

Just because a man glances up at the sky at night does not make him an astronomer, you know.

. . .only the victims and survivors can truly comprehend the awfulness of that time and place; the rest of us live on the other side of the fence, staring through from our own comfortable place, trying in our own clumsy ways to make sense of it all.
