As much as it is important to understand and learn about narcissists, it is equally important to learn about ourselves. I highly recommend this book for anyone that has been subject to narcissistic abuse, especially recurring relationships that seem to end in disaster. As a recovered codependent, this book was instrumental in my recovery. In many ways, it seems like I was reading my autobiography. It is an excellent resource for understanding gaslighting, codependency, and complex PTSD.
