I used to complain about there not being enough bi or lesbian main female characters in books, until about a year ago when I realised there are a fuckload of f/f books out there and it would be almost impossible to read them all.
As a present to you, here’s some good ones:
- Historical bi French lady who crossdresses and is an opera singer and swordswoman: Goddess by Kelly Gardiner
- Lesbian gladiatrix from Sparta: Gladiatrix series by Russell Whitfield (tw: rape)
- Cyber lesbians saving the world: Counting to Zero by A.J. Quinn
- Historical? wlw warriors: When Women Were Warriors by Catherine M. Wilson (I’ve only read the first book so far, but I expect the others are just as good)
- Lesbians in historical/fantasy harem: Nights of Silk and Sapphire by Amber Jacobs
- Early lesbian and vampire lit: Carmilla by J. Sheridan
- Historical lesbians caught in natural disaster: Shaken to the Core by Jae
- 1920s f/f romance turned crime novel: The Paying Guests by Sarah Waters
- Light, humorous f/f fantasy: The Second Mango by Shira Glassman
Disclaimer: Some of these have explicit sex scenes, some do not. Some have happy endings, some have ambiguous or not happy endings.
