Query: Um, what?

I may not be the sharpest knife in the drawer, but this book left me flat and somewhat agitated. I couldn't wait to be finished with it. Long winded diatribes, strange presumptions, crazy metaphors, when there was a point to make it took half a chapter to do it, other wise it kind of ambled along begging for somewhere to go. I'm not trying to be unkind, but I still have no clue what this book was about. I had to select 1 star, but I really mean zero stars.
