I don't want to make myself sound that spontaneous, because I'm not.

I creep over to my chair and sit there with my notebook and my thermos of coffee. It's my best time for thinking, because I haven't started thinking about anything else yet, and the thoughts can kind of go in and out of my head.

There will be scenes in a movie where people are walking through the park, or through a forest, and you're seeing the flickering leaves around them, and they're walking, but you're also hearing their words. It's an interaction between where they are and what they're saying that's both visual and verbal.

One of my favorite moments in that book [As Easy as Falling Off the Face of the Earth] was when something happened that I had no idea was going to happen.

I don't think about it that much, but sometimes I am surprised by that. I sometimes wonder why I didn't turn out to be the kind of picture-book writer who has stuffed animals that go with their books. That would be okay with me.

Some of it just involved thinking about, for example, the different kinds of science, what chemistry is.

I had read [Charles] Dickens's novels were often published serially. I thought it would be fun to write a book, just sitting down and writing a chapter every day, not knowing what would happen next. So that's how I wrote the first draft. And then of course I had to go back and make sure everything worked and change things.
