During the last night of his life on July 25, 1533, the Inca Emperor Atahualpa sent a direct order to Ruminahui, his most trusted field commander, to hide all of the empire's gold. At the time, Ruminahui was leading a train of 11,000 llamas and mules laden with the gold across the Andes Mountains to Cajamarca in Northern Peru. Upon receiving the directive, the commander immediately complied, and fled into the Llanganati Wilderness, only to be pursued by the Conquistador Gonzalo Pizarro and one thousand Spanish soldiers. One year later, Conquistador Pizarro returned to Cajamarca with barely a dozen men and without the gold. For the next five centuries, hundreds of expeditions costing millions of dollars would be undertaken to find the lost treasure known as 'El Dorado' or the 'Lost Inca Gold'. Yet, the location of Atahualpa's gold remains a mystery. On a warm autumn day, Professor Grant Cole sits behind a desk in Seville, Spain, reading an ancient manuscript and inadvertently stumbles over a shocking detail involving Atahualpa's treasure. This newfound knowledge will pit him against powerful worldwide intelligence agencies as well as Vatican envoys and the world's most notorious drug trafficker. Thrust into the center of the centuries-old search for the Lost Inca Gold, Cole will be relentlessly pursued. He finds help from an unexpected ally. Halston Von Thiakopolous is an impulsive and wealthy reality television star, but beneath that superficial image is a fierce and determined woman. Together, Grant and Halston will plunge into the violent and mysterious world of El Dorado in their quest to answer one of the world's greatest mysteries before they become its latest victims.
