I read this something like 10 years ago and just remember that it blew my mind. Tough Native American construction workers who build stuff out in space. I remember they had amazing balance and great heads for heights, and they were very spiritual--they had managed to reconcile their earth-based culture with their lives in space.
This pathetic "review" does not do the book justice, but I haven't read it in a long time. I remember there was a lot of action in the story, and (I think) a murder?
I will have to dig it out and read it again.
