I know the description talked about us talking about us giving recommendations of the best in a variety of media along with good and problematic exemplars of representation.
I'm a bi trans woman and have done a lot of looking for works I can see myself in and looking for trans authors writing trans characters and trans actors playing trans characters in genre fiction.
Julie recommended limiting discussion to recent things, which makes sense and I wonder how recent we should aim for -- probably at least deep enough in the past to include our guest of honor's 2021 novel. Though I may also want to call attention to Rachel Pollack, who passed in 2023, and among other things was a trans woman and an author who introduced the first trans woman superhero to one of the big two, with Coagula in Doom Patrol in 1993, and now we have Jadzia Axelrod's Galaxy showing up in her run of Hawkgirl last year, and Charlie Jane Anders' Escapade in her run on The New Mutants ending this year as well.
Charlie Jane's YA series: Unstoppable, was amazing and wrapped up this year.
I'm not sure how old hat things like The Sandman season 1, or Star Trek Discovery Season 4, should be considered for scope -- though the Quantum Leap revival, which has nonbinary actor Mason Alexander Park playing nonbinary character Ian as a series regular, had a great episode in February 2023 focused on the trans girls in high school sports issue.
I've read a couple of other 2023 novels by trans authors with trans characters, but a late 2022 novel was Maya Deane's Wrath Goddess Sing, with a trans Achilleas.
For problematic things -- the big thing I've got concerns about are what feels like premature cancellations of various projects with LGBTQ stories in them - Batgirl being the most disappointing one recently for me.
Aand I've got a quibble with Russel T. Davies "binary nonbinary" line in Doctor Who six weeks ago.
