Nicole Disney’s The Clinch is a yuri (female/female) MMA romance. Boy, I never thought I’d be having one of those highlighted on Fuldapocalypse. Anyway, it works very well as both a romance (the main character Eden Bauer is very well developed) and as a mixed martial arts book (Disney is experienced in martial arts herself, and it shows.)
There are a few quibbles, all of which are still highly forgivable. In the book the UFC women’s featherweight division is big and prestigious. In real life it’s a tiny skeleton consisting of just Amanda Nunes and her next tomato can victim. There’s also characters having too much situational awareness in the middle of a fight, which is understandable for literary reasons but still comes across as a little forced and unrealistic.
Still, this is the best mixed martial arts novel I’ve read, romance or not.
