Not Long After. By the time I'm done with a novel, I'm ready to move on. But I may be writing some more short stories about Nadya and her decendants. As for creative ideas, they come from everywhere. You have to be alert when traveling in Asia or traveling with people in leather.
Genres are tricky.
The Falling Woman is contemporary psychological fantasy, I think. The City, Not Long After is SF and Magic Realism, I think. And the Shadow Hunter blends SF and Neanderthal fantasy. As you can tell, I don't like boundaries and boxes. I write what the story requires and let the publishers decide what category it fits.
