Anyone know any good non fiction books about native Americans?

Charles C. Mann 1491: New Revelations of the Americas Before Columbus is an award-winning and excellently written book that debunks a lot of myths about American colonialism and the indigenous people that were there. He also wrote 1493: Uncovering the New World Columbus Created.
Highly recommend getting some Vine Deloria Jr. in your diet: Custer Died for Your Sins is probably his most well-known book. If you care about religion. God Is Red might be compelling to you.
- The Charles Mann one looks perfect! I'm getting it now thanks 😊

Empire of the Summer Moon, by S.C. Gwynne. Really interesting read about the final years of the Old West, and the war between the (predominantly Comanche) natives and the white settlers. Been a while since I read it but I enjoyed it.
- That sounds good, what did you like about it?
  
  Decent easy to read narrative which gave perspective of the whole country, and then focused specifically on the fight in the South. Talks about the culture and history of the tribes, and settlers, and then follows a few specific characters so you can observe the personal impact of events.

I can recommend The Rediscovery of America by Ned Blackhawk. It discusses the pre-colonial history and civilizations of America.

Not in particular, but a good place to check would be websites for local bookstores in US states with a strong native American presence, such as NM and AZ
