This thread is starting a nice list of authors I need to get off my backside and actually READ! This includes:
Emma Donahue
April Sinclair
Jeannette Winterson
and a scattering of books like The Fires of Bride and Jacqueline Carey’s Kushiel books, and Larissa Lai’s “Salt Fish Girl”.
…and a whole thread on SF/F lesbian-themed books with too many recommendations to retype here!
