The bone labyrinth
a Sigma Force novel
"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. 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 questions can be answered, 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. 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. Only this time, Sigma will falter--and the world we know will change forever."--
Beyond its central premise, the book can be read through the connected lenses of Fiction, Nonfiction. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.

A more thoughtful way into this book
This guide uses the edition details and category signals above to help you choose deliberately. It does not replace the author's work or a full review.
Best when you want to settle into a longer reading experience.
Begin with its place in Fiction, then notice where the book resists that label.
Read for connection, not completion.
Mark one passage that sharpens the book's central concern and one that complicates it. That tension often reveals more than a quick summary.
Three questions to carry with you
- What does the central character want, and what do they misunderstand about that desire?
- Which detail or relationship changes how you interpret the story?
- What feeling or question does the book leave with you after the plot moves on?
