Comanche Moon is the second book in the Lonesome Dove series and continues the journey of  Texas Rangers Woodrow Call and Augustus McCrae as they try to tame the west from a dwindling but wildly fierce number of hostile Comanche tribesman. Buffalo Hump continues to lead his people against the encroaching caucasian intruders and we follow his story to the end, and his tale becomes a symbol of the weakening state of the once proud and free native peoples. We also meet Blue Duck, the main antagonist in Lonesome Dove, who is Buffalo Hump's half Comanche half Mexican son. Blue Duck never got along with his father and his disrespect for the old ways leads to him being cast out by his father.
