With the title of this book I expected to have my ears blown back. Instead the message seems to be "be afraid, be very afraid." I must admit I did not read the cited books but my feeling is that the book itself should contain supporting information. The examples given where islands in thought not really connected with each other. The message that came through most clearly for me was "wow, can you believe there are people like this out there." Which makes it a good book for people just coming to the subject but if the word sociopath is already in your vocabulary I would skip this book.
