Chapter 19 is nearly complete. Under normal circumstances, it would have been finished and posted a couple weeks ago.
Unfortunately (or fortunately depending on your point of view) I have almost no free time at the moment. I've been working 60 or more hours a week since early March, with significant personal commitments on the side, leaving me with very little time to write. Given that I am a slow, methodical writer to begin with, that seriously hinders my output.
I expect my schedule to lighten up and return to normal before the end of April. It is entirely possible that chapter 19 will be ready for posting before then, but I can make no promises.
Right now, I must sleep.
