I have a mix of good and bad news.
The bad news is that I haven't had much time to do any writing recently as in an average of two days off a month for the past few months. I've been inching forward weekly on the next two chapters.
The good news is that starting in July I should have one or more days free a week which should let me get more done.
Also, I'm posting the final version of Chapter 19. I've had it done for a while, but there isn't a big difference so I wasn't rushing to repost -- I expanded one conversation slightly, added a line to allow for a minor point in the next chapter and fixed a few grammar/spelling/format errors.
