These days I do all my novel 'reading' on Audible. All those years in IT and staring at a computer screen seem to have taken a toll and I like to give my eyes a rest and exercise my ears when I can.
I noticed that both "Through the Gate in the Sea" and "Gears of Faith" are both not available on Audible. Sent out a few emails and so far I received an email from Macmillan Audio stating that they do not have the rights for either of these novels :-(
They mentioned that maybe "Audible Studios" could help. I believe they produced some of the earlier Pathfinder Tales audio books.
Not sure if anything can be done until a new publisher is found for Pathfinder Tales (and hopefully Starfinder Tales), but thought I would mention it just in case.
Having just finished listening to Beyond the Pool of Stars, I too came to the realization that the sequel is not available in audio form. Really hope this is in the works somewhere.
I have been looking for the rest of the novels to be added as well. I have most of them already, and want the rest to be there when I get to them. For the most part they have done a good job with them, besides the fact that they change the reader on some books written by the same author so the characters take on different personalities. Looking for some new stuff as well! Forgotten Realms Novels, Dragonlance Novels, now Pathfinder Tales! They cant all die!
