"You play baseball like a girl." That's exactly what Felix Mccormick said to Harper Quincy, 'baseball queen' as her friends like to call her. Of course she plays ball like a girl. She is, in fact, a girl. Harper has been living in Georgia all her life. She's the best baseball player their town's got, but the problem is, she's a girl. When she follows the local boys to the sandlot one day, will they accept her? They practically hate her, anyways. Harper is determined to change the reputation for girls in her town. But, will it even happen, with Felix and the rest of the boys hating her? Will they ever put their differences aside, and make friends?
