The Ennegram is a remarkable personality typing system that defines nine types of people and how they relate. It also explains why we behave in the way we do by uncovering our unconscious motivations and deeply rooted influences. With vivid examples and insightful description, Palmer introduces the nine types -- Perfectionist, Giver, Performer, Romantic, Observer, Trooper, Epicure, Boss, and Mediator -- and illuminates each one's strengths, weakness, and potenials. Examining each type individually and in connection to other's, Palmer shows how all our relationships in love and work can thrive with a newfound understanding of our similarities and differences.
