It *seems* helpful, but it's definitely self-published and there was obviously no editor involved--there are lots of typos and grammatical mistakes, and as mentioned by another reviewer, it is quite repetitive. A short book that could have been half as long. And there's nothing original in here except for the author's recounting of some experiences she had as a child of a narcissist. Is the author really a "doctor"? If you Google her, all you find are her (many)(short) books; there's not a real author's bio to be found. We know nothing about her education or credentials. In fact, someone in therapy who has read up on narcissism could have written this book.
