I've got 45000 words done on Venus, but the going has slowed. The action is ramping up towards the climax, and I'm trying to get it right, and it's not easy.
I've started thinking through potential plots for Mercury and Mars, the other two books in the trilogy. No outlines yet--only vague notions of what I want to happen.
I'm thinking about a third Buddy story, too. That's way in the future, though, and whether I do it or not will depend on how Buddy: Evolution performs in the marketplace.
