Plummer's book is considered an invaluable glimpse into the culture and mindset of the Comanche as a people before disease and war forced them onto reservations. She not only recounted her feelings about her captivity, but detailed the life, lifestyle, and much as she could, the mindset of the Comanche. She detailed the roles men, women, children, and temporary captives or "slaves," played in that society, and why. In her account of her life among the Comanche, Rachel wrote that six weeks after giving birth to a healthy son, the warriors decided she was slowed too much by childcare, and threw her son down on the ground. When he stopped moving, they left her to bury him. When she revived him, they returned and tied the infant to a rope, and dragged him through cactuses until the frail, tiny body was literally torn to pieces.
