There is pressure when you have a very big book like 'Shadow Divers' to follow up with something big. But you can't let that pressure determine what you do. You just look for the best stories, and when you find a great one, you tell it.

For my new book 'Pirate Hunters', I follow John Chatterton and John Mattera, two world-class scuba divers, who teach themselves to think and act as pirates while searching for what would be only the second pirate ship ever found and positively identified.

I'm a product of the 1970s, so I have a short attention span. You know, I grew up on cartoons and half-hour shows. So the stories that I'm interested in grab my attention very quickly, and they have to keep my attention.

This constant pressure from record companies to come up with a hit single or something like that, I find completely tiresome.

I like to find things that are unconventional and make them look classic, because if I'm forcing something, you can just tell.

I just wanted to paint and sketch and tell stories by drawing.
