A clinical social worker who has practiced psychotherapy with a psychoanalytic orientation for more than 25 years, Edward here focuses on the role siblings play in each other's development in order to demonstrate the necessity for therapists to give siblings a place in the therapeutic context. She begins by focusing on sibling attachments, which provide not only security but also an internalization of interpersonal exchanges that influences how they relate to others throughout the life span. Subsequent chapters address such issues as the impact of the wider culture on sibling relationships; the impact of envy, rivalry, and hatred, which can lead to pathology; sexual activity between siblings; and the influence of a developmental disability or serious illness on the sibling relationship. A chapter addressing the effect of the death of a sibling on surviving brothers and sisters was especially interesting. Blending findings from case studies with results from quantitative research and information revealed in memoirs, biographies, and even fiction, Edward builds the case that therapists ought to give their patients' siblings a place in their treatment efforts. Summing Up: Recommended. Lower- and upper-division undergraduates, graduate students, professionals, general readers.
