Yesterday was a thinking day. I wasn't happy with how I'd ended a chapter the day before, so I backed up and had a think about it. I knew the next 7-10K worth of stuff I wanted to have happen, but the puzzle pieces weren't coming together into a picture I was happy with.
I think I got it shuffled in the right order, and as of tonight I'm at 31,000 words. It's a clear path 'til the midpoint now. After that I may have to take another day to plot and think.
