It is an interesting book, but I'm not sure that it's a book that you read in one sitting. I say this because there's no real flow to the book. The authors might address drug dealers in one chapter, and African-American names in the next. The result is that you don't necessarily build up any momentum as you move from one chapter to the next.
Don't get me wrong, this is an interesting book, and you will find the mental gymnastics that the authors have produced stimulating (because it is cleverly written). However, I don't think it's written in the most fluid way possible, and that's why I'm not raving about this book.
