"Sisters are doing it for themselves," sings Annie Lennox.

In this classic and far-ranging portrait of sisterhood Peterson explores a hilarious slumber party, a singing duo of sisters about to find their fame, a Zulu tribe of sisters, the chosen sisterhood of Isabel Allende and Tabra Tunoa, and the sisterhood of animals, such as dolphins and elephants. Weaving memoir, research, interviews, and lively storytelling, Peterson celebrates how the feminine can balance and restore our health and survival. Her well-told insights from psychology, mythology, history, and anthropology reveal the enduring alliance of sisterhoods - from childhood bonds to growing old together as Crones.
