New York: Grand Central Publishing, (2017) dj. Hardcover first edition - A book which surpasses his fiction in adventure and suspense. "In 2012, Preston joined a team of explorers searching for Ciudad Blanca ('The White City'), a legendary ruin hidden in the dense jungle of eastern Honduras. The city also known as 'the Lost City of the Monkey God' - was literally a legend; while various hucksters and hoaxers had claimed to have discovered the abandoned metropolis, no credible evidence had ever been presented. In addition to the objective hazards of tropical disease, wild boars, and the deadly fer-de-lance viper, locals stoked the mystique, describing various curses awaiting would-be discoverers. But this team had an advantage that previous searchers had lacked: LIDAR, an advanced laser-imaging technology able to penetrate the dense jungle canopy - just enough - and return detailed elevation profiles from which subtle, man-made anomalies could be identified. Almost immediately, two major sites emerged, their scale and architecture indicating a civilization to rival another local, more famous power, the Maya." But the dangers were real- and Preston and several other contracted a horrifying disease in the jungle. Illustrated with photographs in color.
