Last book I read was Black Elk Speaks by John Gneisenau Neihardt.

Interesting book.  It's basically a guy who met an old Native American wiseman who decided to use him as a conduit to tell his story.  Ended up having a few of his friends who had been there for some of the crazy stuff come by to tell their stories too.

These were oooooold ass dudes when it was written, and it was written in 1932 so it's a cool look at the past.  Do recommend if that's the sort of thing you're interested in.
