As a companion piece to his books Gender Matters and Boys Adrift, in Girls on the Edge Dr. Leonard Sax addresses the four crises young women are faced with today: sexual identity, the “Cyberbubble,” environmental toxins, and obsessions. Sax, an advocate of single-gender education, combines good research with easy-reading case studies to show these identifiable problems. He suggests that finding intergenerational voices and advocates in established communities can promote healthy growth for women, not only in mind and body, but in spirituality as well. (Basic Books)
