Non-Fiction book about Native Americans, specifically the Comanche Nation

Hello all,

I just finished reading the Lonesome Dove series where they are met with numerous Comanche along with other members of assorted tribes. While reading, McMurty did a great job at giving the mentioned Comanches a great story. Although fictional, I would like to learn more about the Comanche nation, along with other tribes. If anybody has a suggestion, I would greatly appreciate it!
