This work is an exploration of the ongoing significance of sisterly relationships throughout life, bringing together personal narrative with the illuminations provided by myth, fairy-tale, and the deep psychological reflections of Freud, Jung, and their followers. The book suggests that an imaginal return to the relationship with the actual sister of early years is only the beginning; it leads forward to an understanding of how that relationship reappears, transformed, in many friendships and love affairs, and to a challenging revision of the innermost self, and even toward a new way of imagining a woman's relation to the natural world. The book in no way sentimentalizes sisterhood. In her retelling of the familiar story about Psyche and Eros Downing focuses on Psyche's relation to her envious sisters who, she suggests, push Psyche in a way her soul requires. Reflection on this aspect of the story initiates women into an appreciation of how sisterly relationships challenge and nurture, even as they sometimes disappoint and betray one another.
