I finally finished the book!
I wasn't going to bed tonight without finishing it. I was so close I could taste it. It was touch-and-go there for a while, but I toughed it out and finished. At 70k words, it's a little short, but I fully expect to add a few thousand words when I go back and make the beginning good, and punch up some of my more "lame now but I'll fix it later" passages.
Also, I need to send my registration for Malice Domestic today. It has to be postmarked by the 15th. Boy, I better get some sleep!
