Well, so far, I spent pretty much this entire month rewriting the part of the original Chapter 16 that I had thought was decent. Now I'm getting to the part that I thought was crap. Odds are that that will turn out to be somewhat easier.
One of the things I've noticed is that I want to put a chapter break between these two sections. That will make Chapter 16 a short one, but there is no dishonor in writing a short chapter. The only dishonor is in writing a bad one.
I'd really like to put Drayton to bed by the end of October so that it doesn't make it to a fourth National Novel Writing Month, but I don't know that I'll make it. It does give me a loose goal to shoot for, though, and anything I can do to keep myself focused is worth it.
