Yes, I've started it. I wasn't even sure what I was going to do for it until I sat down. But I managed to find a way to transition from the two opening chapters I tacked on and slip back into my original outline. Not that I'll manage to stick to the outline from here on out. But you've got to start with something, don't you?
Anyway, 275 words, some research, and some reorganizing and we're still underway.
