Query: Do not waste your money

I read this book because I had to: I was reviewing it for The Edmonton Journal. My conclusion is simple and straightforward: while beautiful, this book is so filled with glaring mistakes, howlers and omissions, its authors and editors should be ashamed of themselves. In fact, if it were possible, I would give this volume no stars at all: the first thing a book on history must have is its facts right.
