I am down to my last two chapters! Soon draft four will be complete!
First I need to re-write chapter 18. The ending-ending is really awesome, but I made the dire mistake of starting the denouement BEFORE the ending. This is always a bad move. It destroys the sense that the story is rising to a spectacular climax! I'll keep the climactic scene at the end of the chapter but replace all the parts at the start that make it sound like the book is already over with scenes that actually build the tension.
Oh this is going to be so good!
