This is the riveting true story of twins separated at birth, and the emotional and psychological challenges they faced after being reunited. Identical twins Anna and Bella were born thirty-seven years ago in Spain's Canary Islands. Due to chaotic conditions at the hospital or simple human error, Anna was unintentionally switched with another infant in the baby nursery. In this fascinating story, Dr. Nancy Segal, herself a twin and an expert in twin research, describes the consequences of this unintentional separation of identical twin sisters. She considers not only the effects on these particular sisters but also the implications of this and similar cases for questions concerning identity, familial bonds, nature-nurture, and the law. The combination of a riveting true story [the twins were reunited age 28] and cutting-edge twin research makes "Someone Else's Twin" an irresistible page-turner.
