I’m not entirely sure of the point of this book. When a guy on Waterstones said that it was, in the end, a great book, that when you get to the end of it you see the world in an entirely different or new way, I felt I had to buy it. More fool me. I see the world in exactly the same way on finishing this book. Except perhaps a larger dollop of cynicism towards Waterstones’ staff with their eagerness to shift stock.
