In 1923, Mary Breckinridge (who had been a nurse in WWI) learned about the nonexistent medical facilities in Appalachian Kentucky, and founded the Frontier Nursing Service -- a group of women who traveled by horseback to isolated mountain residents to provide medical care. These three compelling, poignant stories, each with a different narrator - a boy whose father almost loses his leg; a nurse in training; a mute young girl who realizes she might have a career in medicine - show Mary's effect on the people and world around her, brought to vivid life by master storyteller Rosemary Wells.
