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.
