The 6th Extinction
Sigma Force Novels - A Sigma Force Novel
This book can be downloaded and read in Apple Books on your Mac or iOS device.
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.
The land is entirely sterile-and the blight is spreading.
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.
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 is it already too late?

This is the best yet in the SIGMA series. I couldn't put it down.
Interesting science, a little hokey, would be a good movie.
Not bad, not great. Couple of hammy scenes but all in all, it makes you think. Would make a good movie.
Probably the best Sigma Force novel to date
With nods to the past but introducing plenty of new material, this book is definitely the best of the Sigma series to date.
