I've started on the last one today. It's coming along slowly. I suppose I have three more days to finish it in, so I'm in no rush.
There will be some gaps left in the narrative, even after I finish this chapter. And it's a very rough draft, replete with continuity errors. (I think at one point I have a character show up who actually died a few chapters earlier. I wrote quite a lot out of sequence and a number of events that I hadn't planned on occured.)
Still, this chapter closes the last significant gap. I'm willing to chalk all the rest of it down to "revision process".
What an odd feeling.
