Staff Reviews

Beginning with the cursed continent of Antarctica, this story unfolds with tales of demons that haunt its dark depths and are ready to eat the hearts of the living. When an emergency 911 call is made from a military research site financed by the U.S. Developmental Test Command, an unbridled discovery is made. With the involvement of Dugway Proving Grounds, a nuclear, chemical, and biological test facility, rumors of extraterrestrial research run rampant among other theories. When biologist Dr. Kendall Hess is kidnapped, the military's Defense Advanced Research Projects Agency that deals with global threats of technological nature is called upon. Sigma Special Forces soldiers comprise this organization. The historical background of Hess involves a career of studying rare bacterial species that thrive in toxic and hostile environments and are capable of existing in foreign worlds. With his knowledge, Hess has become an immediate target for others to gain from technologies intersecting between biology and physical science encompassing everything from genetic engineering to synthetic biology. Hess's radical research provides information on unusual biochemical molecular processes forming exotic life forms. A power struggle ensues between good and evil to prevent the end of the human race and civilization.
Mass extinction has become the newest subject matter created by James Rollins. The creation of over a thousand new aggressive XNA species using biological experimentation represents the threat of annihilation on our present ecosystem. Completion of this undertaking comprises a man-made disease that dulls and corrodes the human brain. It strips away intelligence making humans inhuman. With the continuation of eliminating many species by humans trampling the environment and causing a rise in pollution, mankind has become the driving force behind a certain road to apocalypse where nothing survives. Rollins skillfully forges true statements with fictional writing to create an underlying message that civilized intelligence can save us from destruction. Continuing his action packed adventure style of writing, Rollins balances scientific facts with the fragility of life. This latest endeavor will undoubtedly place the reader neck deep in the Sixth Extinction.

— Mike, Albuquerque


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?
