Parasite is the first book I've written largely in secret. Not because I was ashamed of it, but because first it wasn't sold, so I couldn't say anything about it. Then it was sold but unannounced, so I couldn't say anything about it. Then, when it was finally announced, I was so far into the writing process that I couldn't force myself into the normal flow of word counts and benchmarks and all the other things I use for motivation.
Pro tip: I work better with word counts and benchmarks. I know this now.
Friday I wound up staying home from my day job, thanks to an inability to breathe that was only resolved when I had another of my amazing fire hose nosebleeds, or, as I like to call them, "blood vacations." (It's not high blood pressure, it's a weakness in one of the blood vessels that runs through my sinuses. My doctor and I have discussed it. So please, no medical advice.) And once I mopped up the blood and got some clean clothes on, I got to work, and quietly, without any real fanfare, passed 500 draft one pages.
It's not a perfect book, by any means; for one thing, it's missing about 8,000 words still, and for another, it hasn't had any editorial, which means that all the Mira Grant "tics"—repetition, over-explanation, Joss-y dialog—are in full display, with no mitigation. But I can see the shape of what will be a good book, once we finish kicking the crap out of it, and that's very reassuring to me.
It will be awesome.
