A remote military research station sends out a frantic distress call, ending with a chilling final command:  Kill us all!  Personnel from the neighboring base rush in to discover everyone already dead-and not just the scientists, but every living thing for fifty square miles is annihilated:  every animal, plant, and insect, even bacteria.<br /><br />The land is entirely sterile-and the blight is spreading.<br /><br />To halt the inevitable, Commander Gray Pierce and Sigma must unravel a threat that rises out of the distant past, to a time when Antarctica was green and all life on Earth balanced upon the blade of a knife.  Following clues from an ancient map rescued from the lost Library of Alexandria, Sigma will discover the truth about an ancient continent, about a new form of death buried under miles of ice.<br /><br />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.<br /><br />But is it already too late?
