Oh, yes; it's an excellent site! I visit it often, sometimes for research to help decide on getting a book or not, and sometimes just for the fun of browsing through. Thanks for providing the link, for easy access!
I had a half-baked idea of dabbling into it a little bit, based on where the series leaves some characters and situations. I felt really bad about Cardassia's suffering, and thought that The Never Ending Sacrifice (which I forgot to include in my above tally) and the WoDS9 Cardassia story would give a look in on how Cardassia fares after the war. I've heard people say The Never Ending Sacrifice is pretty user friendly, and shows the Dominion War from the perspective of the Cardassian youth who gets shipped back to Cardassia in the episode "Cardassians". I can't remember if I heard that The Never Ending Sacrifice goes beyond the war into the reconstruction. I was also left feeling curious about how Rom does as Grand Negus (I ended up liking Rom so much, seeing how his life changed throughout the show), and wondered if the WoDS9: Ferenginar story would show how Rom adjusts to that role.
Those are my immediate interests in the aftermath of the DS9 finale, but if the answers to those situations are scattered throughout the DS9 relaunch novels from the beginning, than I'm game to start there. Otherwise, I figured I would dabble with some of the WoDS9 that sound interesting, The Never Ending Sacrifice, and then go back to the start of the DS9 relaunch novels. And revisit the WoDS9 collection in order, the second time around.
Thank you for the feedback about the novels that fill the gap, the remaining Mission: Gamma novels, ect. Only four novels in that gap sounds very manageable!
