Shamanism by Leo Rutherford
My partner got me this book a few months back, and I put it on the pile with the other books that I had to read. But that same week I couldn't stop thinking about that book, so stopped reading a Edain McCoy book and got stuck in with this one. And I can not put this book down! For people who want a brief introduction to shamanism then I really do suggest this book, it isn't that heavy to read. He has put it into nice little paragraphs so you don't feel like you are reading an essay.
So yes this book is an amazingly good book to read! :)
