Its been a month and I have news. Book 4 is much closer to being a thing!
After monkey-banging on the keyboard for a month I thought I had better get some feedback from one of my editors.
Good news is that he says the first few chapters are passable. Enough so that I will continue to give my muse monkey-chow and let it continue hammering away.
The bad news is that there is still really no ETA. Much remains in limbo at how to steer this ship that has just gotten underway so you will just have to wait till future updates which sadly, will likely just tell you how much longer you'll need to wait.
But, odds are now higher that there will be a continuation of Johns story.
Thanks for your patronage.
