It was supposed to have vanished 30 million years ago. Now it's back— and the ocean will never be the same.
When an Antarctic ice shelf collapses, something long entombed is set free: Basilosaurus, a sixty-foot toothed whale apex predator from the Eocene Epoch, more powerful and cunning than any shark or whale alive today. First, a diver vanishes in waters off California. Then a surfer. A luxury yacht is torn apart. As the body count rises, marine paleontologist Dr. Laura Keating and cetacean expert Dr. Evan Holt are drawn into a desperate hunt—while the Department of Homeland Security tries to contain the truth.
But Basilosaurus isn't just hunting humans. Orcas, great white sharks, and the delicate balance of ocean life are under siege. Nature itself recoils from the return of a predator its inhabitants remember only in ancestral terror. And when a second Basilosaurus emerges, their coordinated strikes threaten to turn the Pacific into a killing ground.
From the deep ice to the deep sea, Basilosaurus is a relentless, high-velocity marine thriller where prehistoric fury collides with modern science—and survival is no longer guaranteed for man or beast.
