This, as it says over there, is surely very close to the final version. It’s always possible I’ll do a little bit of last-minute tweaking, but if that happens, it really should be minimal.
The cover is underway, but will not be available until April. I’ll load the final version, including any tweaks and corrected typos, at that point. I’ll set the preorder to drop at Amazon in November or maybe even December. I’ll leave the book at my Patreon for at least a month, but not all the way to the release date.
