Reese Callahan writes dark MMA romance set in the world of underground fight gyms. Bare-knuckle coaches who don't know how to be gentle. Female fighters who don't want them to be. Power exchange in the cage and out of it. Cage violence, bruises that take weeks to heal, and a love story that doesn't pretend it wasn't earned by punishment. Penelope Douglas, Lauren Asher, and the Sons of Anarchy soundtrack are on Reese's gym playlist. Standalones with HEA endings — and a fight scene every single one of them deserves.
