Some trans authors I enjoy: Charlie Jane Anders (science-fiction), S. Bear Bergman (nonfiction), Immogen Binnie (contemporary fiction), Stephanie Bert (nonfiction), Thomas Page McBee (autobiography/nonfiction), Zoë Estelle Hitzel (poetry)
Some nobinary and genderqueer authors I enjoy: Kate Bornstein (nonfiction), Danez Smith (poetry)
There's also a great Goodreads list called "Trans Books by Trans Authors" that I've been reading through sporadically in an effort to diversify my reading this year. Here's the link: https://www.goodreads.com/---/91823.Trans_Books_by_Trans_Authors
(edited to add Zoë Estelle Hitzel - completely forgot how much I love her poetry)
