A remote military research station sends out a frantic stress call, ending using a chilling final order: Kill us all! Personnel from the neighboring base rush directly into discover everyone already dead-and not only the scientists, but every living issue for fifty square mls can be annihilated: every animal, place, and insect, even bacteria.

The property is entirely sterile-and the blight is spreading.

To prevent the unavoidable, Commander Gray Pierce and Sigma must unravel a threat that rises out of the faraway past, to a period when Antarctica was green and all life on Earth well balanced upon the blade of the knife. Following signs from an ancient map rescued from your dropped Library of Alexandria, Sigma will quickly realize the reality about a historical continent, in regards to a new type of loss of life buried under mls of ice.

From millennia-old secrets out of the frozen past to mysteries buried deep in the darkest jungles of today, Sigma will face its greatest challenge to date: stopping the coming extinction of mankind.

But could it be already too late?
