Query: Total waste of time

A friend gave me this book and highly recommended it. To this day I have no idea what I did to offend her. Whatever it was, she got even by getting me to waste my time with this boring story that had no redeeming value. I kept reading because I expected there to be more to it-ie that somehow it would all come together and the time investment would be rewarded by a clever lesson or a deep meaning. When I finished, I discovered that there was actually less than met the eye- no lesson, no moral, no clever ending. Do yourself a favor and do not buy this book--- unless of course you plan to give it to someone who has offended you.
