Recently divorced Tina Durham is trying to be self-sufficient, but her personal-training career is floundering, her closest friends are swept up in new relationships, and her washing machine has just flooded her kitchen. It’s enough to make a girl cry.

Instead, she calls a plumbing service, and Joanne “Joe Mama” Delario comes to the rescue. Joe is sweet, funny, and good at fixing things. She also sees something special in Tina and invites her to try out for the roller derby team she coaches.

Derby offers Tina an outlet for her frustrations, a chance to excel, and the female friendships she’s never had before. And as Tina starts to thrive at derby, the tension between her and Joe cranks up. Despite their player/coach relationship, they give in to their mutual attraction. Sex in secret is hot, but Tina can’t help but want more.

With work still on the rocks and her relationship in the closet, Tina is forced to reevaluate her life. Can she be content with a secret lover? Or with being dependent on someone else again? It’s time for Tina to tackle her fears, both on and off the track.
