I have a copy of this book that does not meet PBS guidelines, so I am offering it here in case anyone wants it.

Link to this book at Amazon:  http://www.amazon.com/Mystic-Warriors-Plains-Culture-Religion/dp/156924538X/ref=sr_1_1?ie=UTF8&s=books&qid=1256741312&sr=8-1

It is a hardback book missing its jacket. 

ISBN is 0-385-04741-X.

It is in very nice shape aside from the following:
* There is a written note on the front (blank) page of the book.
* The front cover of the book jacket has been cut out and taped to the inside cover.
* The binding has come off from the pages and the book is "split" in two sections.  They are both still attached to the binding, but are not attached to each other.  This is in the middle of the book.

This book is very heavy and normally expensive.  I hope someone can use it.  :)
