By examining case studies, the authors of The Narcissistic Family demonstrate that some families, that might be considered normal functioning from the outside, are in fact, operating narcissistically, and can have a disabling emotional impact on a child - showing that it isn't only overt emotional or physical abuse that causes long term dissociation and harmful behaviour.The reader gets a close up and revealing look at the formation of narcissistic behaviour and tendencies, and the negative thought loops associated with them that can lead to depression.Highly recommended.
