The lost city of Z - David Grann

Colonel Percy Harrison Fawcett was the last of a breed of great British explorers who ventured into 'blank spots' on the map with little more than a machete, a compass and unwavering sense of purpose. In 1925, one of the few remaining blank spots in the world was in the Amazon. Fawcett believed the impenetrable jungle held a secret to a large, complex civilization like El Dorado, which he christened the 'City of Z'. When he and his son set out to find it, hoping to make one of the most important archeological discoveries in history, they warned that none should follow them in the event that they did not return. They vanished without a trace. For the next eighty years, hordes of explorers -- shocked that a man many deemed invincible could disappear in a land he knew better than anyone, and drawn by the centuries-old myth of El Dorado -- searched for the expedition and the city. Many died from starvation, disease, attacks by wild animals, and poisonous arrows. Others simply vanished.
In The Lost City of Z, David Grann ventures into the hazardous wild world of the Amazon to retrace the footsteps of the great Colonel Fawcett and his followers, in a bracing attempt to solve one of the greatest mysteries. It is an irresistibly readable adventure story, a subtle examination of the strange and often violent encounters between Europeans and Amazonian tribes and a tale of lethal obsession.
