Query: The Best Book I Have Read On Narcissism

I am a sufferer of pathological narcissism myself, and this book is hands down the best I have come across to date. The main reason? Dr. Johnson's extensive knowledge of his subject is EMPATHICALLY INFORMED. This adds a entire dimension to his work that is missing in the writings of many so-called experts. It engenders something in a sufferer that is often overlooked by those who consider themselves on the cutting edge of research into pathological narcissism: HOPE. There are no words to describe the value of realistic hope to a narcissistic individual who is working toward characterological transformation. This is a work of quiet competence, a labor of love, and a very fair treatment of a highly polarized subject, based on actual experience with narcissistic clients. Literally, a lifesaver for me.
