Last night, I decided to look over the final chapter even though I am still some way from reaching it for revision. I'm glad I did.
I think it wasn't much of an ending, one more suited to a broad comedy than to the book it has become. I've got a few weeks to turn it over before I need to really deal with it, which is a plus, but the revision will ultimately be substantial enough that I think I might have to put that rewrite on hold for a while even then.
In the meantime, I have four chapter to rewrite, one of which (I think Chapter 17, which I am starting work on today) will include an entire scene that never existed before. That's a lot of work and all the while I'll be thinking about the damn ending.
It would be so much easier to do a crap job and probably more profitable, too. Unfortunately, I am stuck with the desire to write something worth writing and, with any luck, worth reading.
But that's the way it goes.
