S.C. "Sam" Gwynne is the author of Empire of the Summer Moon: Quanah Parker and the Rise and Fall of the Comanches, the Most Powerful Indian Tribe in American History, a finalist for the Pulitzer Prize in 2011, a National Book Critics Circle Award Finalist and the winner of both the Texas and Oklahoma Book Awards. It paints the epic story of the Comanches, whose territory comprised an estimated 250,000 square miles of the American Plains, an area now part of five states. It also draws the more intimate story of Cynthia Ann Parker, a nine-year old girl who was kidnapped by Comanches during a raid on the family's Texas homestead. Parker subsequently spent 24 years with the tribe and had three children, including Quanah, who would become one of the Comanche's most skilled warriors.
