An alarming rise in the world's sea levels-much greater than could be accounted for by glacier melt-sends Kurt Austin, Joe Zavala, and the rest of the NUMA scientific team rocketing around the globe in search of answers. When they begin to suspect a mysterious underwater mining operation in the East China Sea, they find their investigation completely blocked by a mystery man with unparalleled technological resources and the services of an assassin so violent even the Yakuza has disowned him. Outmatched and outmanned, it'll take everything NUMA has to stop the threat of complete global submersion. And that's only the beginning of their problems. Whatever this new adversary is after at the bottom of the Earth's surface, it's only one piece of a plan to upset the balance of power in the Pacific-and in the process displace as many as a billion people. To protect this enterprise, he's bringing all of his resources together to create a weapon fit to become a very personal nightmare for Kurt Austin. --[Book Jacket].
