Sam Vaknin was very kind and did the forward for Dark Souls.  I also asked Sam if I could have permission to use some of the quotes from his book.

Much of Sam's work is about understanding the Narcissist from the narcissists point of view. He delves into the mind of the Malignant Narcissist in his book "Malignant Self Love - Narcissism Revisited" 

You can find out about Sam Vaknin's extensive work and articles on Narcissism and Narcissistic Personality disorder at his website

www.narcissistic-abuse.com

I had initially decided to contact Sam because he is one of the few people apart from other professionals who write about it who actually has the condition himself and so he writes from his own personal experience. 

Many professionals talk about NDP, Narcissism, sociopathy or psychopathy and yet very few of them have had experiences of actually having been in relationship with them themselves. Therefore I felt it important that people could understand more about Narcissists not just from professionals but from those who were victims like myself but those who actually suffered from NPD.
