Query: Very Interesting

There is definitely a unique flavor to this book. The beginning is very attention grabbing. The next few chapters get a bit confusing. But, as you persist reading on, you notice that there are a few concepts discussed every here and there that are entirely unique. The parts that were confusing, I didn't have enough time to sit down and put myself in the "author's shoes". However, I do plan to return to the book another time, and when I do have more time to think, I plan to see if I can see what the author is trying to say. I do like his unique creativity. I don't think there is another book like it. I did pay almost $50 for this book. Although I think it's a bit overpriced, I have no regrets, since the money is for a good cause.
