The book is 'From the Gathering: The Wisdom of Little Crow' (Carl Bryant)
Have you looked at Exode?
It's a new game, and it would be nice to have some different words and ideas, It's still in the early stages of development. And the Captains(players) can input ideas and I've read a bit of Lakota Author Sci-Fi in the past(can't remember the name now), A Ghost Walker Robot uprising with Environmental disaster type vibes.
