All this back and forth is messing up my headspace. I've never had two novels seriously on the go at the same time before. And it seems to take me at least a few days to get my brain to stop obsessing about the one and switch over to the other. Right now I'm in the middle part where I can't think clearly about either one... or indeed any kind of writing at all.
