Probably all the books I've ever written have been efforts to define the boundaries of humanity.

The Berserkers have been with me for about forty years, and we're not done yet.

And what we know, or think we know, about the universe of space and time is changing very quickly.

I have some good stories yet to tell.

More immediately, I'm currently working on another Dracula in which there will be connections with ancient Egypt. That's about as far as I want to go in commenting on current work.

The comments I most appreciate come from ordinary readers who've happened on one of my books at some time of stress in their lives, and who actually credit the book with helping them through a bad time. It's happened a few times in forty years.

Actually ideas are everywhere. It's the paperwork, that is, sitting down and thinking them into a coherent story, trying to find just the right words, that can and usually does get to be labor.
