The 6th Extinction

In a masterful epic of timeless mystery and ripped-from-the-headlines scientific intrigue, New York Times bestselling author James Rollins takes mankind to its endpoint, to a fate written in rock and ice in an event known as The Sixth Extinction.
A remote military research station broadcasts a frantic distress call that ends with a chilling message: Kill us all. When soldiers arrive to investigate, they discover everyone in the lab is dead — not just the scientists, but every living thing for fifty square miles is annihilated: every animal, plant, and insect, even bacteria. The land is completely sterile — and the blight is spreading.
To prevent the inevitable, Commander Gray Pierce and Sigma must decipher a threat that rises out of the distant past, a time when Antarctica was green and Earth’s life balanced on a knife edge. Following clues from an ancient map rescued from the lost Library of Alexandria, Sigma will make a shocking discovery involving a prehistoric continent, and a new form of death buried under miles 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 yet: stopping the coming extinction of mankind.
But is it already too late?
