This work is an exploration of the ongoing significance of sister relationships throughout our lives, bringing together personal narrative with the illuminations provided by myth, fairy tale, and the depth psychological reflections of Freud, Jung, and their followers. The book suggests that an imaginal return to our relationship with the actual sister of our early years is only the beginning; it leads forward to an understanding of how that relationship reappears, transformed, in many of our friendships and love affairs, and to a challenging revision of our innermost self, and even toward a new way of imaging our 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. Reflections on this aspect of the story initiates us into an appreciation of how our sisterly relationships challenge and nurture us, even as we sometimes disappoint and betray one another.
