In the latest riveting thriller from James Rollins, the #1 New York Times bestselling author of the Sigma Force series, 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.
