I'm pretty sure this was one of the most important books (maybe the most important) I have read in my life. I can't comprehend how many times I nodded while the author explained narcissism and the patterns. I never in my life made so many notes in a book because it resonated completely with me and with what I went through. Highly recommend it to everyone. If you are stuck in a narcissistic relationship, if you want to learn more about narcissism or if you just want to read a really informative, insightful psychological book.
