I heartily applaud the author for addressing subject matter normally left to the far right, such as immigration, nationalism, the influence of well-meaning liberalism on Europe, diversity and integration and the 'threat' within. The author also makes the fair point that european societies were too rigid, weak and insecure to make incoming immigrants feel loyalty to their host - a point rammed home by the fact it has taken an American to write a book about immigrations impact on european culture. Despite this being a serious book it is written in an accessible style - a bit like a toned down, more intellectual, Ann Coulter. I found this book so important and relevant to today's ever changing world that I read it in 3 days - it being a semi-permanent appendage to my right hand. If you want a thoughtful, well-argued book that will make you think again about issues you may have already decided upon, then this is a must buy. If you like this I also recommend another book about race and diversity - although from an English/Nigerian perspective, check out:One Love Two Colours: The Unlikely Marriage of a Punk Rocker and His African Queen by Margaret Oshindele - a book that shows how a Nigerian woman can integrate into the cultural way of life of England - without giving up her own Yoruba culture. Another book that would serve as an interesting companion to this book is: Bloody Foreigners by Robert Winder.
