Morgan VanDolen is an accomplished athlete, but joining a softball team for the first time as an adult threatens to pitch some dents into her pride. In the face of a frustrating learning curve, Morgan finds inspiration in her new teammate: Marina Martin. A Snow White beauty with a Mona Lisa smile, Marina is as talented as she is attractive. There's just one hitch: Marina is in a relationship. With a man. But Morgan has cause to hope: Marina is bisexual. At least, Marina thinks she is. Her lack of experience has led to a lifetime of self-doubt, which isn't helped by others' perceptions of bisexual women in "straight" relationships. Marina wants to settle her doubts once and for all, but will circumstances ever allow it?
