American journalist and writer Tracy Kidder, a Pulitzer Prize winner, tells the incredible story of Paul Farmer, a doctor who dreams of curing all the sick in the world. Farmer's main goal is to provide qualified medical care to the poorest people in countries where people are dying from tuberculosis and other infectious diseases that are easily treatable with the necessary drugs and equipment. The NGO “Partners for Health” created by Farmer today carries out this task at the international level. The Zanmi Lasante Medical Center in Haiti, which he founded, is tangible proof that goodwill can work miracles and restore hope even where it has been forgotten. The reader will see Haiti, Peru, Cuba, Russia through the eyes of Farmer, transforming minds and systems in accordance with his motto: “The only nationality is man.”
