Though a woman's life and the world around them may change, it's the promise of friendship that remains an irreplaceable constant. From their biological and cultural origins to the varied manifestations of social connections, this book explores the deep bonds forged between women. By sharing stories from girls and women throughout their lives, the authors thoughtfully illustrate the roles that contemporary social relationships play at different stages in our lives while offering insights to deeper self-understanding and for finding, establishing, and sustaining relationships at any age.
