I will have a houseguest unexpectedly this weekend, but she's okay with me virtually abandoning her while I work. I need to send the manuscript back next week.
I also sent off a blurb I'd promised someone. I think they wanted it sooner than they got it, but, well, I was busy. And it's now done, so I don't have to ponder it any more, and can go back to my own novel.
I don't plan to work on the pirate novel at the same time as I'm doing final changes on Moonlight Mistress, but I had some new thoughts while I was at WisCon that should help, mostly about the secondary characters.
