Mountains Beyond Mountains is a biography by Tracy Kidder about Paul Farmer, a physician who worked to fight tuberculosis in Russia, Peru and Haiti. The biography, told from the author's perspective, chronicles Farmer's life, his broken engagement to Ophelia Dahl, his work for Partners in Health and his numerous accomplishments. Kidder characterizes Farmer as hard-working, unpretentious and kind man who acted more than preached, simply living his life in accordance with what he believed would help others.
