The audios are produced by Big Finish: https://www.bigfinish.com/. I'm in a bit of a moral quandary with helping *coughcoughahem* these - I have no moral issues with it for big-corporation TV shows, but I really want to encourage Big Finish to keep making these, because as long as they do, we keep getting new adventures with the original cast! And I want them to get paid for it. On the other hand, they cost as much as books do, and there are no library options for them that I know of. Hence a moral quandary I don't really have a resolution for. I wonder if they have gift certificates ...
Anyway though, these are my favorites of the ones I've listened to so far; there are quite a few I don't have yet.
The Last Beacon (Owen & Ianto) - This is light, fun, hopeful, and generally adorable; it's one of the few that's unreservedly optimistic and happy. It's written by Gareth David Lloyd (Ianto's actor) who very clearly just wants his character to have a road trip with Owen and become better friends.
Dinner and a Show (Ianto & Tosh) - Another one written by Gareth David Lloyd and demonstrating once again that his dream episode is Ianto hanging out and being friends with his teammates. This one's a bit darker and sadder than the above one, but it also gives better Tosh than 90% of the series does; one thing I notice when I go back to the show after listening to this is how much more resilient, funny, and bold Tosh is written here than she generally gets to be on the show.
Moving Target and Sync (Suzie) - The two Suzie-centric audios, both of which have almost the same plot (Suzie is forced to team up with someone she doesn't like while aliens try to kill her). I liked the first a bit better overall, but I preferred the ending of the second, and enjoyed both of them a lot.
Iceberg (Owen) - This starts off light and fun, and gets increasingly depressing with a horribly dark ending, but you also get to see a lot more of Owen's sympathetic side, and Owen being a doctor.
Cascade (Tosh) - This one does really nice things with the general conceit that you're listening to a corrupted recording that's spliced together out of order and kills people who listen to it.
The Office of Never Was (Ianto) - Another one that starts off funny and takes a downhill slide into absolutely horrifying, including Ianto making a very dark decision at the end. But it has a lot of parts that are really fun, and the mystery of a haunted building that traps Ianto after hours is spooky and fun.
The Hope (Owen & Andy, Gwen's police friend) - I don't know if this one would be to your taste; it's fairly dark, the plot concerns a serial killer and Owen undercover in a prison, but I ended up really loving it, and it has a surprisingly upbeat ending for how dark the rest of it is (also I want to write fanfic for it).
Dissected (Martha & Gwen) - This is funny and poignant, and I really liked it. It's set after Children of Earth, so Torchwood at this point consists almost entirely of Gwen, which added an underlayer of profound sadness that made me realize I don't know how many of the ones set after season two I can handle. But the Martha and Gwen interactions are really lovely.
