This is one man's fight to save lives in Haiti and everywhere. Profound and powerful, "Mountains Beyond Mountains" takes us from Harvard to Haiti, Peru, Cuba and Russia, as the charismatic but flawed genius Dr Paul Farmer challenges widely-held preconceptions about poverty and healthcare. As a medical student, Farmer found his life's calling: to cure infectious diseases and to bring the lifesaving tools of modern medicine - so readily available in the developed world - to those who need them most. Beginning in Haiti, he tackles the conditions that contribute to so many unnecessary deaths with his trademark combination of world-class expertise, unlimited compassion, and the unstinting dedication of friends and colleagues. Tracy Kidder's magnificent and moving account shows how, from achieving this modest dream, one person can make a difference in solving global problems through a clear-eyed understanding of the interaction of politics, wealth, social systems and medicine.
