There are actually quite a few side stories.
I have another series I am working on called “The Chronicles of Astlan” that are shorter novels that cover the side stories that tie in to the main book, but require so much detail that it would be distracting in DoA.
The first CoA book, “Into the Wilds” will be coming out shortly after Book 3. I am working on it now as well as book 3, and hope to do a lot more writing on it during the beta and editing of book 3. I would expect it about 3 months after book 3 if all goes well.
Additional books in CoA may or may not continue previous books in CoA. I.e. they may be completely different side stories.
Tizzy’s garden is contained in one of these side stories of CoA.
As an FYI, I have thoughts/plans for other related series, but those are not yet at a writing stage.
Seas of Astlan would basically be the Asmeth story along with the rogues that stole the book for Lenamare.
The Oak Orcs of the Antilles covers Trig Bioblast and crew as they seek to rid their universe of the influence of the Alvaran Empire and other nasty deep space baddies.
