I think I've figured out a way to add life to the mid-book, which was looking a bit too straightforward. One of the nice things about gaining experience in writing is that I have come to have greater confidence in my ability to solve problems. I might not know the entire path, but I am certain that I will know the way by the time I get there.
Of course, the more of this I write, the more certain I am that it is fundamentally too weird for anyone else to ever want to read it, but that bridge is a long, long way off.
