It's a quite ambitious book and covers a lot of history, so I just link it's wikipedia site rather than explain it with my broken english:

Not really only about native Americans, but I thought that The Dawn of Everything was really interesting and it had a lot of history about different native American societies.

I am playing Dark Light at the moment and I don't know where to fuck should I go?

Still too many sales.

Maybe I Am Future has some gameplay mechanics you could steal:
