It's been a while on account of having a full time job, but the 5th book, Of Wits and Weapons: Rise of the Holy Empress, is now available in paperback and ebook formats. Check it out at https://www.amazon.com/dp/B09TN45J1J

Oh, and you can bet I'm still working on the sixth book. Granted, it's slow going and I'm finding myself in a bit of a slump... Hopefully I can manage a release for that one by the end of 2022.
