Gabby's summer vacation isn't shaping up to be that great. Her dad was just deployed overseas, and Gabby is staying at her grandmother's house with her mom and baby sister until he returns.

The one bright spot is that Gaby plans to sign up for the local softball league--her greatest love and a passion she shares with her Dad who was a pitcher in college. But when Gabby goes to sign up for the summer league, she discovers that there wasn't enough interest to justify a girl's team this year. And to top it off, a horrible miscommunication ends with Gabby signed up to participate in the Miss Popcorn Festival--the annual pageant that Gabby's mom dominated when she was younger.

Besides not having any interest in the pageant life, Gabby made a promise to her dad that she would play softball for the summer. Since her pitching skills rival any boy her age, Gabby creates a master plan: disguise herself as a boy and sign up for the boy's baseball team instead--and try to win the pageant to make Mom happy. Can Gabby juggle perfecting her pageant walk and perfecting her fastball? Or will this plan strike out?
