If you don't want to have any of your views challenged or at least put in question, then don't read this book. You can learn something new from this book: it tells you about different worlds, which are probably not your own. If you just want someone to tell you about the world you already know, and confirm what you already think, then there are many many other books around that do that. This book takes you on a journey of discovery around the earth, showing you what it looks like, how it feels, when the third world comes first, not last. It will be different, it may make you feel uncomfortable, you may feel that it is turning your world upside down, but its an amazing, positive and heartening human experience you will never forget.
