The first comprehensive, interdisciplinary book on compersion. Drawing from philosophy, psychology, anthropology, and the helping professions, the author includes her own groundbreaking, rigorous research alongside vivid stories and practical advice from interviews with racially, ethnically, and gender-diverse people in CNM relationships.

Based on seminal research with consensually non-monogamous (CNM) individuals, Dr. Marie Thouin elucidates this question of compersion from several lenses and introduces the first comprehensive and applicable model of compersion-an essential tool for scholars, therapists, and CNM individuals alike.
