Eris: Sacred Feminine Force of Evolutionary Astrology is the first in-depth examination of Eris through Jeffrey Wolf Green's Evolutionary Astrology. Usually viewed as a goddess of chaos and discord, Eris is presented here as a potent force for personal and global evolution-exposing shadows, demanding honesty, and urging the soul toward transformation. Daniel Fiverson draws on decades of experience in the JWG tradition for this groundbreaking study. With mythic grounding, historical context, and detailed chart analysis, he explains how Eris functions in the natal chart, through transit, and within relationship dynamics. Each chapter presents Eris as an essential archetype-one that clarifies unresolved desires, illuminates the evolutionary path, and calls for acknowledging what has been denied or marginalized. For practicing astrologers, this book expands the interpretive framework of Evolutionary Astrology and offers practical tools for working with clients. For students of the tradition, it provides a dynamic transmission of the Pluto-node method, now strengthened by Eris's unwavering voice. Eris does not comfort; she confronts. She is not an outsider; she has taken her seat at the table. In these pages, you will learn how to interpret her presence in the chart-and why no evolutionary reading is complete without her.
