I would not recommend this book to people who are interested in gaining a deeper knowledge in personality disorders. Buying this book I thought I would get a better insight to narcissism as well as understand how NPD is developed and how to deal and protect your personality from people suffering from narcissistic personality disorder. Although the author states in the beginning that she does not pretend to be a professional psychiatrist throughout my reading I felt very clearly that the book is written by an amateur. In my opinion it fails to get inside the world of a narcissist, understand mechanisms underlying his/her behaviour patterns etc. though the author is very good at writing a narrative story.
