Publisher's Summary

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 50 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

Third Rollins book in a row diminished by Narrator

Where does The 6th Extinction rank among all the audiobooks you’ve listened to so far?

I have listened to all Sigma Force novels prior to this and loved them until recently. Vibrant characters from the past are all muted now. Storyline is appealing but the attempt to view the next chapter in their lives is tepid. All characters are barely recognizable now due to the newly inserted narrator.

Who was your favorite character and why?

Sadly none. No fire.

Would you be willing to try another one of Christian Baskous’s performances?

This is my last try with this narrator. His voice and performance are wispy and poignant. A grandfather telling a fairy tale. He does not fit these books.

Narrator is Horrendous!

What did you love best about The 6th Extinction?

Good story. Suspenceful.

Would you recommend The 6th Extinction to your friends? Why or why not?

Yes. Good story.

How could the performance have been better?

The narrator could have given a darn. He reads it like he wants to get home for dinner. Good story wasted on poor narrator.
