Query: This book stinks.

I read this book because of the other good reviews I saw on this site. My god!! It is one of the worst books I've ever read. I suffered through to the very end to see if it would vindicate the earlier chapters. Boy did I make a mistake. Unless you are some sort of 'new age' hippy wannabe, you will hate this book. Don't bother.
