What exactly was the difference? he wondered to himself. And who decided which people wore the striped pajamas and which people wore the uniforms?

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 started reading Dickens when I was about 12, and I particularly liked all of the orphan books. I always liked books about young people who are left on their own with the world, and the four children's books I've written feature that very thing: children that are abandoned by their families or running away from their families or ignored by their families and having to grow up quicker than they should, like David Copperfield - having to be the hero of their own story.
