(this review is for the hardback version, I am making the assumption they are the same). I skimmed parts of the book, since I don't know (or care) about the intricacies of golf swings. Admittedly, the author thinks most pros overly complicate them as well.
However, even saying that, I enjoyed the book. This surprised me, since it was about golf. The authors have a good tone--I felt often like I was sitting at a dinner table swapping stories. Good enough story teller to make them interesting even when the apparent subject matter (golf) was not. He has a good sense of humor as well.
Much of what he talks about is life more than golf. The problems with golf are often found outside the swing--be they from poor teachers, mental blocks, practice requirements, behavior, etc.
I really liked the point he made that if you don't play as well as the rest of your group--just play. As long as you aren't holding everyone else up, the rest won't mind you aren't as good. Don't yell and scream and complain, just play.
Whether you are interested in golf or not, it's a nice light book. If you like golf you would probably enjoy it even more.
