Thank you! I still have three or four chapters to write and then quite a bit of editing to go on the whole. I think a finished e-book is at least two months out, but I'll see what I can do about a preview release.
The main problem is I don't currently have a way to contact folks who are interested! I'll maybe add a mailing list signup form to subscribe for updates. Meanwhile, I am posting updates to my blog (https://dusty.phillips.codes), which has an RSS feed, as well as to LinkedIn (https://www.linkedin.com/in/dusty-phillips/) and Facebook Author page (https://www.facebook.com/dustyphillipsauthor). I think Patreon also has an option to follow me without sponsoring, but I'm not clear on what gets posted to that feed (haven't been too impressed with Patreon, TBH).
