One of my favorite non-fiction books of all time is S.C. Gwynne's Empire of the Summer Moon, which tells the dramatic story of Quanah Parker and the Comanches. Quanah was the son of Cynthia Ann Parker, a frontier girl who was kidnapped by the Comanches when she was 9 years old and recaptured by the Texas Rangers when she was about 33. Her son Quanah went on to become a great warrior for the Comanches. In this episode, I revisit a fascinating 2019 conversation with Gwynne.
