Amy's dad is away, fighting in World War II, and her mama must take a job. But it's no ordinary job--Amy's mother becomes a baseball player in the first professional women's league. Amy cheers louder than anyone at all of the home games. And while Mama's team travels, Amy works on a secret project--a surprise for her dad when he is finally back home. With warmhearted, historically based text and lush illustrations, award-winning author David A. Adler and talented new artist Chris O'Leary bring to life the soaring spirit of the 1940s. Featured in the major motion picture A League of Their Own , the All-American Girls Professional League helped women prove that no war could stop the great game of baseball. An author's note provides historical context for the era.
