Tracy Kidder is a winner of the Pulitzer Prize and the author of the bestsellers The Soul of a New Machine, House, Among Schoolchildren, and Home Town. He has been described by the Baltimore Sun as the "master of the non-fiction narrative." This powerful and inspiring new book shows how one person can make a difference, as Kidder tells the true story of a gifted man who is in love with the world and has set out to do all he can to cure it.

At the center of Mountains Beyond Mountains stands Paul Farmer. Doctor, Harvard professor, renowned infectious-disease specialist, anthropologist, the recipient of a MacArthur "genius" grant, world-class Robin Hood, Farmer was brought up in a bus and on a boat, and in medical school found his life's calling: to diagnose and cure infectious diseases and to bring the lifesaving tools of modern medicine to those who need them most. This magnificent book shows how radical change can be fostered in situations that seem insurmountable, and it also shows how a meaningful life can be created, as Farmer -- brilliant, charismatic, charming, both a leader in international health and a doctor who finds time to make house calls in Boston and the mountains of Haiti -- blasts through convention to get results.
