What's funny about that is when I was writing Twilight just for myself and not thinking of it as a book, I was not thinking about publishing, and yet at the same time I was casting it in my head. Because when I read books, I see them very visually.

If I were to continue on with 'The Host,' which is a possibility, there are characters and stories that could continue... If I went ahead with that, it would be two more... Next would be 'The Soul,' and then 'The Seeker.'

When I first started with 'Twilight,' I didn't have any experience. I didn't know what I was doing. So I was pretty intimidated by the editors and the publishers, and I felt like I was a kid in school with the principal telling me what to do! It was hard for me.

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.
