Popular wisdom might suggest that jealousy is an inevitable outcome of non-monogamous relationships. In Love's Refraction, Jillian Deri explores the distinctive question of how and why polyamorists - people who practice consensual non-monogamy - manage jealousy. Her focus is on the polyamorist concept of compersion - taking pleasure in a lover's other romantic and sexual encounters. By discussing the experiences of queer, lesbian, and bisexual polyamorous women, Deri highlights the social and structural context that surrounds jealousy. Her analysis, making use of the sociology of emotion and feminist intersectionality theory, shows how polyamory challenges traditional emotional and sexual norms. Clear and concise, Love's Refraction speaks to both the academic and the polyamorous community. Deri lets her interviewees speak for themselves, linking academic theory and personal experiences in a sophisticated, engaging, and accessible way.
