I might be too busy, but I want to try anyway. I already work on projects & I already try to keep things casual for rough drafts, so nano would be like... business as usual, but with more to connect with people about? Yeah!
My current project is a novel idea that turned into a trilogy idea, with books 1 and 2 covering the original idea and book 3 rounding things out with more payoff and satisfaction. I've been working on book 1, but book 2 is ready to go anyway. If I write a nanowrimo version of book 2, that could be a great new angle for looking at everything in book 1 when I get back to it.
