Keith O'Brien weaves together the stories of five remarkable women: Florence Klingensmith, a high school dropout who worked for a dry cleaner in Fargo, North Dakota; Ruth Elder, an Alabama housewife; Amelia Earhart, the most famous, but not necessarily the most skilled; Ruth Nichols, who chafed at the constraints of her blue blood family's expectations; and Louise Thaden, the mother of two young kids who got her start selling coal in Wichita, Kansas. Together they fought for the chance to race against the men--and in 1936, one of them would triumph in the toughest race of all.
