This book suffers from a major lack of identity. The title of the book might lead you to believe that it's about The Map That Changed the World and how William Smith created it. However, the book is all over the place. There are countless sentences which are about one thing, then have a random jab at religion thrown in at the last second; the author often throws in details about people who, he openly admits in the text, had nothing to do with Smith's life or work; and, the language is confusing -- it's verbose, meandering, and, on several occasions, contradictory. Frequently, I'd have to reread a sentence multiple times because it would use positive adjectives to describe some thing negatively. It was as if he was raving about how great an event was and then ending with "unfortunately". I would be left confused, "was that meant as a good thing or a bad thing?" "What was he trying to say?"
I give the book 3 stars because it did give some good information about Smith's work, and I really wanted that information. Unless you have a particular interest in this subject, like I do, this book might not be worth your time, money, or effort.
