Book excerpt: The Many Faces of Polyamory: Longing and Belonging in Concurrent Relationships provides new perspectives on polyamory and the longing to belong in the relatively uncharted territory of nonnormative relationships. This volume offers a valuable and compelling account on how to approach polyamorous relationships from the clinical perspective. While there is no uniform answer, Dr. Fosse’s compassionate and discerning approach that combines relative neutrality, an open-minded embrace of nontraditional lifestyle choices, and skilful attention to countertransference dynamics is likely to be inspiring. Dr. Fosse exposes the dynamics of love, sex, jealousy, and compersion as they play out in lives of those interested in polyamory, and more broadly, consensual nonmonogamy. Her focus is on relationships worth having. With its nuanced clinical focus, The Many Faces of Polyamory will be an essential resource for psychotherapists, educators, students, and anyone inside and outside of the mental health field drawn to the intricacies of sexuality, intimacy, and how they are intertwined with relational satisfaction
