Listened to this audiobook as part of some research I am doing, rather than for personal reasons.
As it was written from personal experience and included real life examples it was certainly enlightening and, at times, frightening. The lengths to which the author's ex-husband would go to maintain control / narcissistic supply were remarkable, particularly his willingness to use his children regardless of the impact it may have on them. Some of his actions were almost unbelievably extreme, but it was the more subtle ones that I find most scary.
This kind of behaviour is so insidious and destructive, and this book is a good resource for getting to know the signs so that it can be curbed before it goes too far (ie, if a possible partner, or even a friend, begins to exhibit similar behaviour, run away, as fast and as far as possible!)
If I had read this rather than listened, I may have scored it a full 5 stars, because I could have skipped over the repetition caused by the style applied to each of the author's anecdotes, which became distracting on the audio version.
