When Dirk Pitt is nearly killed rescuing an oil survey team from a freak wave on Russia's Lake Baikal, it appears a simple act of nature. When the survey team is abducted and Pitt's research vessel nearly sunk, however, it's obvious there's something more sinister involved. All trails lead to Mongolia, and a mysterious mogul who is conducting covert deals for supplying oil to the Chinese while wreaking havoc on global oil markets utilizing a secret technology. The Mongolian harbors a dream of restoring the conquests of his ancestors, and holds a dark secret about Genghis Khan that just might give him the wealth and power to make that dream come true.
