Commander Gray Pierce and Sigma Force face their deadliest mission when the Titan Project research station off Australia's coast discovers bioluminescent coral in dead waters. The discovery attracts deadly attention. A military submarine vanishes in the area, triggering a vicious assault on the station. The attack unleashes geological chaos across the region. Massive earthquakes shake the ocean floor. Volcanic eruptions spew ash and fire. Tsunamis crash into coastlines. Something ancient stirs miles beneath the waves, a threat buried for thousands of years. Seas turn poisonous. Shores burn. An old enemy emerges to hunt Pierce and his team, blocking their efforts at every turn. Pierce must dig into Aboriginal mythology to find answers hidden in the past.
