The Bone Labyrinth A Sigma Force Novel

In #1 New York Times bestselling author James Rollins’s fascinating thriller, 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. . . .

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?

When the investigative team is attacked and a bloody assault is made upon a primate research center outside of Atlanta, 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.

Along the way, revelations involving the lost continent of Atlantis will reveal true mysteries tied to mankind’s first steps on the moon. Gray Pierce and his team will face 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.
