When Kat Miller first tries out for the All-American Girls Professional Softball League, she thinks how exciting it would be to get paid to play the game she loves. But then she actually makes a team. She struggles with long road trips, grueling practices, and the challenge of making time for God. Not only that, but older teammates are jealous of her success and an irritating reporter, Jack Raymond, has a knack for getting under Kat’s skin.

Jack lives with the shame of being physically disqualified from joining the American forces in World War II. Events in his career have left him cynical and distanced from God. That is, until Kat walks into his life. She challenges his preconceptions and refuses to compromise her beliefs, no matter what difficulties she faces. Will the flames of disappointment forge bitterness in his heart, or can the promises Kat reminds him of restore joy to Jack’s life?
