I'm not primarily a Comanche historian, but I do study Native American history, so take this as an experienced, but not expert, opinion.

From all I've read Hämäläinen's Comanche Empire is a great place to start diving into the history of specific Native American nations. Hämäläinen did an amazing job in describing the Comanche from their perspective, and world view, instead of previous popular history which firmly grounds the narrative from the point of view of Europeans looking across the frontier. While this narrative shift seems almost normal now, it was historians like Hämäläinen who transformed how we tell the story of North America to a popular history audience. Instead of just mentioning indigenous peoples when a European happens to stumble into them, the foundation for these new stories is set firmly in Indian Country. Nations like the Comanches are considered on their own terms, as independent nations seeking their own goals in their own timeframe. Richter's Facing East From Indian Country and Calloway's One Vast Winter Count are other great resources, as is Masters of Empire by McDonnell about the Anishinaabeg of the Great Lakes. A little closer to your home, and recently released is Fifth Sun, which is a history of the Aztecs told from indigenous sources. All this to say, Comanche Empire is one of those good books that not only teaches you something new, but helps transform how you view the history of North America, contact, colonialism, and the dynamic indigenous response to a changing landscape.
