I found this book a bit difficult to follow, but it was interesting all the same. Four Native American men escape from the local mental hospital, all bearing well-known fictional names (i.e. Robinson Crusoe), but whether they are actually really humans, or spirits or some other fantasy creation is never really clear. They interact in the ordinary lives of other Native Americans going about their day to day lives -- dating problems, working, serving dog meat to tourists as "real indian" food, etc. The author seems to have a good understanding of the culture, and blends his reality and pseudoreality well -- you're just never quite sure where the line is drawn.
