I was very disappointed to find out that this book is poorly written. The writing style seems amateurish and contrived. While the information itself seems interesting, its delivery leaves a lot to be desired. Overall, I'm only giving it 1 star because Amazon does not allow zero stars. My recommendation is skip this book. You can get more info on various sites for free. I will probably never do business with amazon.com ever again.
Bad review
