Ki, Kim, and Ledingham have done a masterful job at providing a truly impressive anthology that captures the development, growth, and future directions of relationship theory. Every chapter is theoretically rich and thought provoking. The topics covered are diverse enough for every reader to find something fresh and resonating. This is a "must have" text for scholars, educators, students and professionals seeking state-of-the-art knowledge about a compelling paradigm for 21st century public relations.
