Dr. Hawa Abdi has been called "the Mother Teresa of Somalia." Since 1991, when the Somali government collapsed, famine struck, and aid groups fled, she has dedicated herself to providing help for people whose lives have been shattered by violence and poverty. In her new memoir, Keeping Hope Alive: One Woman: 90,000 Lives Changed , she talks about founding a camp for internally displaced people located outside war-torn Mogadishu, Somalia. She also tells of being kidnapped by radical insurgents, who also destroyed much of her hospital, because she was a woman. She, along with media pressure, convinced the rebels to let her go, and she demanded and received a written apology. She's joined by her daughter, Dr. Deqo Mohamed.
