Colonel Percy Harrison Fawcett, the inspiration behind Conan Doyle’s novel The Lost World, was among the last of a legendary breed of British explorers. For years he explored the Amazon and came to believe that its jungle concealed a large, complex civilization, like Eldorado. Obsessed with its discovery, he christened it the City of Z. In 1925, Fawcett headed into the wilderness wiht his son Jack, vowing to make history. They vanished without a trace.

For the next eighty years, hordes of explorers plunged into the jungle, trying to find evidence of Fawcett’s party, or Z. Some died from disease and starvation; others simply disappeared. In this spellbindning true tale of lethal obession, David Gran retraces the footsteps of Fawcett and his followers as he unravels one of the greatest mysteries of exploration.
