Here are a few recommendations for books that can help you deal with the narcissist(s) in your life.
The Wizard of Oz and Other Narcissists: Coping with the One-Way Relationship in Work, Love, and Family by Eleanor Payson available at Amazon.com.
Emotional Vampires: Dealing With People Who Drain You Dry by Albert J. Bernstein. This book gets mixed reviews for its extensive use of the vampire metaphor. Some find it tedious, others entertaining. I am one who found it entertaining. The book has quite a bit of practical advice which is often hard to come by in books on this topic. The book seems targeted more toward those dealing with narcissists and other personality-disordered people in the workplace. The advice can apply to other contexts as well.
In Sheep's Clothing: Understanding and Dealing with Manipulative People by George K. Simon. This is a must have book for anyone. We all have had to deal with manipulative people and can be assured we'll have to again. This book takes a very frank view of the subject and helps to clarify what is really happening when someone is trying to manipulate you.
