Amazon.com description: Product Description: Sisterhood is one of women's most significant life relationships. Through interviews and questionnaires with more than 150 women, author Elizabeth Fishel poignantly explores the depth and breadth of this bond, revealing intense rivalry, unwavering devotion, and profound ambivalance, as well as sisters' influence on each other's sexualty and creativity, the implications of birth order, and the patterns of family roles. Among the well-known sisters included in the book are Margaret Mead (who called the sister bond "probably the most competitive relationship within the family"), Gloria Steinem, Carly Simon, Ntozake Shange, and Kate Millet.
