I read the reviews on Amazon.com as well as other media before ordering the book. I new that Amazon would take it back if it was not up to my expectations, so I took the plunge. To my great delight, I found the book to be more than interesting- it is exciting! I'm a bookaholic - but this book would appeal to even those folks who don't usually like to read. The information leaps off the page because of the great graphic format. A couple of the graphs have information that simply can't be correct - but I have checked several in other sources and they are surprising, but correct. Buy this book and leave it on a table - your teenagers will pick it up and learn by accident.
