Well, today I got about 800 words written. It may not sound like much, but it gives me a great sense of satisfaction to sit down and create something that wasn't there before. Add that to the scribbling I've done for the last two days, and I have another 2000 words to add to my word count.
My shiny new Chapter 20 is not healthy, however. It is woefully short, length-wise. I am putting it aside and moving on, however, and intend to revisit it in the Big Revision. I have this lingering fantasy that once I start revising things, some of these weak places will resolve themselves.
