I really like to plow straight through the first draft, however often the plot suddenly turns on itself and surprises me, figuring to fix it in the rewrite. Sometimes, however, there are just too many unexpected changes, and I have to stop and get things in line before I got on.
Iorich just did that, around chapter 11. The rewrite is complete, and now there’s a chapter 12 to go with it. So things progress.
