I've had a lot going on. Taxes. Work changes. Etc. It's made getting the edit for Ch. 20 difficult to make time for. On top of that, it's half again as long as the average chapter.
It is in progress, and I'm going to hit the next step later this evening. I also caught myself in a continuity error in Ch. 21, so I'm having to fix several scenes and transitions in that in order to get back on track. It's at about the halfway mark, minus those tweaks.
