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.

The thing about exploring is that you have to know whether the thing you've found is worth finding. Some things are just sitting there, minding their own business, waiting to be discovered. Like America. And other things are probably better off left alone. Like a dead mouse at the back of the cupboard.

I like the idea of standalone novels. I always found with series of books, it's something that publishers love obviously because they can make a lot of money and they build an audience from book to book, but I don't like that as a writer. I prefer the idea of just telling a story, completing it within your book, and moving on and not forcing a child to read eight of them.

I was a very quiet child, quite introverted, really. Independent, yes; I didn't need a lot of supervision. Less so than I did when I got older, maybe. But I was a bookish child, not surprisingly. I could sit quite happily in a corner for hours and entertain myself with books.

...Despite the mayhem that followed, Bruno found that he was still holding Shmuel's hand in his own and nothing in the world would have persuaded him to let go.

There is cruelty in the world Eliza, you can see that, can't you? It surrounds us. It breathes on us. We spend our life trying to escape it.

Bruno: We're not supposed to be friends, you and me. We're meant to be enemies. Did you know that?
