I was standing by the microwave, waiting impatiently for my pasta to heat up, when an entire novel popped into my head. And if it pans out, I know exactly what I'm writing for Nano08 and I can't wait. See Humor!Suspense/Thriller genre (think Chuck, but with an even MORE everyday woman), and that's essentially the idea.
And this wasn't the only writing project to pop into my head today, but it *is* the only one I can talk about, since the other involves a certain someone whose birthday is coming up :P
