The Bone Labyrinth: A Sigma Force Novel (Sigma Force Novels)

A war is coming, a battle that will stretch from the prehistoric forests of the ancient past to the cutting-edge research labs of today, all to reveal a true mystery buried deep within our DNA, a mystery that will leave readers changed forever . . .

In this groundbreaking masterpiece of ingenuity and intrigue that spans 50,000 years in human history, New York Times bestselling author James Rollins takes us to mankind’s next great leap.

But will it mark a new chapter in our development . . . or our extinction?

In the remote mountains of Croatia, an archaeologist makes a strange discovery:  a subterranean Catholic chapel, hidden for centuries, holds the bones of a Neanderthal woman. In the same cavern system, elaborate primitive paintings tell the story of an immense battle between tribes of Neanderthals and monstrous shadowy figures. Who is this mysterious enemy depicted in these ancient drawings and what do the paintings mean?

Before any answers could be made, the investigative team is attacked, while at the same time, a bloody assault is made upon a primate research center outside of Atlanta. How are these events connected? Who is behind these attacks?  The search for the truth will take Commander Gray Pierce of Sigma Force 50,000 years into the past. As he and Sigma trace the evolution of human intelligence to its true source, they will be plunged into a cataclysmic battle for the future of humanity that stretches across the globe . . . and beyond.

With the fate of our future at stake, Sigma embarks on its most harrowing odyssey ever—a breathtaking quest that will take them from ancient tunnels in Ecuador that span the breadth of South America to a millennia-old necropolis holding the bones of our ancestors. Along the way, revelations involving the lost continent of Atlantis will reveal true mysteries tied to mankind’s first steps on the moon. In the end, Gray Pierce and his team will face to their greatest threat: an ancient evil, resurrected by modern genetic science, strong enough to bring about the end of man’s dominance on this planet.

Only this time, Sigma will falter—and the world we know will change forever.

  1. Quick Warning but a Wow of a Book! I’m going to start this review with a warning. If you are sensitive to scenes featuring animal experimentation, you may find part of this book a hard read. The scenes are heartrending – especially when you get to know one of the animals involved. That being said, the scenes are well written and absolutely critical to the book. 

  2. Indiana Jones meets Da Vinci Code Lena Crandall and her sister Maria Crandall are scientists that both work on why human intelligence began to blossom 50,000 years ago. Lena is a paleontologist and along with Father Roland, the English geologist Alex Wrightson, and the French paleontologist Dayne Arnaud, she is exploring an underground cave in Croatia for hominid bones. That cave is now under attack by some kind of special forces. Wrightson and Arnaud surrender without revealing that Lena and Father Roland are with them…

  3. The Bone Labyrinth: A Sigma Force Novel A fine addition to the Sigma Force Novels. Frankly I’d been disappointed with some of the latest entries in the series. I’m pleased to report The Bone Labyrinth is a return to what I expect from James Rollins . A rollicking adventure stepped in history and science. Well paced . Featuring old friends. Highly recommended for both fans of Rollins and the casual reader of thrillers.
