I've backed up a bit. While reading and revising the other day, I came to a point where I felt everything up to that point had been at least OK, but everything after was really bothering me. I've gone further back, added a bit to a scene, and I'm now in the process of trying to derail/re-rail what happens after the problem point. What this means is that roughly four thousand words out of nearly forty five thousand are... if not completely lost, at least in serious jeopardy.
Which is not so bad. So, I'm back to 41k. But it's better, I think.
And I'm calling it a novel. So there.
