Since the days of Cortés, rumors have circulated about a lost city of immense wealth hidden somewhere in the Honduran interior, called the White City or the Lost City of the Monkey God. In 1940 journalist Theodore Morde returned from the rainforest with hundreds of artifacts and an electrifying story of having found the Lost City-- but then committed suicide without revealing its location. In 2012 Preston joined a team of scientists using classified technology that could map the terrain under the densest rainforest canopy. They found evidence of not just an undiscovered city but an enigmatic, lost civilization-- and returned carrying a horrifying, sometimes lethal-- and incurable-- disease.
