I don't know who they are[my characters] . They're entirely invented characters. Maybe that's how I've been able to write so many books, because there are no boundaries for me. I can write a completely fantastical story like "Swept Away" or "Blinded by the Light" and then a non-comic drama like "Chicxulub" or something like "Birnam Wood" that has autobiographical underpinnings. Why not?
