From award-winning author Mara Rockliff and New York Times -bestselling illustrator Elizabeth Baddeley comes this extraordinary picture book about one little girl who loved sports and grew up to be one of the greatest and best-known tennis players of all time. Anything Billie Jean did, she did it ALL THE WAY. When she ran, she ran fast . When she played, she played hard . As a top women's tennis player, Billie Jean fought for fairness in women's sports, and when she faced off against Bobby Riggs in the Battle of the Sexes, the most famous tennis match in history, she showed the world that men and women--and boys and girls--are equal on and off the court.
