From the #1 New York Times master of international thrillers comes the story of a hunt across the globe, pitting nation against nation, as ancient myths of a lost continent prove all too real.
The execution of a Vatican archivist within the shadow of the Kremlin exposes a conspiracy going back three centuries—to the bloody era of the Russian Tsars. Before his murder, he manages to dispatch a coded message, a warning of a terrifying threat, one tied to a secret buried within the Golden Library of Tsars, a vast and treasured archive that had vanished into history.
As combative forces race for the truth behind this death and alarming discovery, Sigma Force is summoned to aid in the search—not only for this missing trove of ancient books, but to follow a trail far into the Arctic, to search for the truth about a lost continent and a revelation that could ignite a global war. But Sigma Force has its own difficulties at home after an explosive attack on the National Mall—one aimed at the heart of their covert agency—has left them vulnerable and exposed.
The growing conflict—both on Russian soil and deep in the Arctic—will reignite a centuries-old war between the newly resurgent Russian Orthodox Church and the Vatican, while sabers rattle across the nations of the Arctic Circle, threatening to turn those icy seas into a fiery conflagration.
Facing enemies on all sides, it will be up to Commander Gray Pierce and Sigma Force to unravel a mystery going back millennia—and uncover the truth about a lost civilization and an arcane treasure that could save the planet…or destroy it.

In the latest riveting thriller from the #1 New York Times bestselling author, an international research station in the Coral Sea comes under siege during a geological disaster that triggers massive quakes, deadly tsunamis, and volcanic eruptions. To stop the world from burning, it’s up to Sigma Force to uncover a secret buried at the heart of our planet.
The Titan Project—an international research station off the coast of Australia—discovers a thriving zone of life in an otherwise dead sea. The area teems with a strange bioluminescent coral that defies science, yet holds great promise for the future. But the loss of a military submarine in the area triggers a brutal attack and sets in motion a geological disaster that destabilizes an entire region.
Massive quakes, volcanic eruptions, and deadly tsunamis herald a greater cataclysm to come—for something is stirring miles under the ocean, a threat hidden for millennia.
As seas turn toxic and coastlines burn, can Sigma Force stop what has been let loose—especially as an old adversary returns, hunting them and thwarting their every move? For any hope of success, Commander Gray Pierce must search for a key buried in the past, hidden deep in Aboriginal mythology. But what Sigma could uncover is even more frightening—something that will shake the very foundations of humanity.
