An enzyme that could dramatically prolong life has been discovered in the North Atlantic — under two thousand feet of icy water in an area known as the "Lost City." But why are the people attempting to harvest its secrets dying mysteriously? Why are scientists from a remote Greek laboratory disappearing one by one? And what does all of this have to do with a body found frozen in the ice high up in the Alps?

          To a family of ruthless French arms dealers, the Lost City is the key to world domination. To Kurt Austin, leader of NUMA’s Special Assignments Team, and his colleague Joe Zavala, it’s clear they have their work cut out for them. But this job may be even bigger than they think — in fact, it may be their greatest, and deadliest, challenge of all.
