Amazingly well written
Format: Hardcover
Nice book. Pictures and honest interviews and reports via credible down to earth persons.
They don't weigh you down with hundreds of pages to read. Well done

Beyond Expectations
Format: Hardcover
Since I have had several experiences I am always looking for something legitimate -something that looks into the heart and truth of the material and comes out authentic to the core - I love this book - It far exceeds what I expected and am very happy I ordered it to add to my collection. This will be on the top of the stack! The only down side is that amazon packaged it rougly where it slid freely about in an overlarge box --This ended up tearing the top of the dj rear --- :( I do hope they do not pack all orders for this bk that way - if there are notes you can add to your order you might request book packaging or something more durable than sliding loosely about I found out about this book on the newsletter I receive from Shirley MacClaine - she always has valuable nuggets to share !!!
