I also just got back into reading, and was curious about the same thing!
I HIGHLY recommend Gender Queer by Maia Kobabe. That's the book that sparked my trans realization, and it's incredibly well illustrated with a wonderful story of eir life (it's a memoir); I've read it 3 times. I actually just bought 5 other queer books, but I have yet to read them:
- Kiss Her Once for Me by Alison Cochrun
- How We Fight For Our Lives by Saeed Jones
- Suicide Notes by Michael Thomas Ford
- Stone Butch Blues by Leslie Feinberg
- The Stonewall Reader by New York Public Library
I can update this comment when I finish reading a book to give my thoughts on them if you'd like!
It's worth looking into Lutris for non-Steam games as well. Comes preinstalled with Bazzite (heavily gaming-optimized Linux distro), though I don't have any non-Steam games to try it on since Steam works fine for all the games I play.
