It was supposed to have vanished 30 million years ago. Now it's back- and the ocean will never be the same.
When a rare natural phenomenon shatters an Antarctic ice shelf, it unleashes something the modern world was never meant to face: Basilosaurus, a sixty-foot carnivorous toothed whale from the Eocene era, cunning, relentless, and perfectly built to rule the seas.
Marine paleontologist Dr. Laura Keating and cetacean expert Dr. Evan Holt are drawn into a race to understand the creature before it reshapes everything humanity-and the ocean-thought it knew about life in the deep. But as the predator begins to move through the Pacific, its presence triggers a chain of events that threatens not only mankind, but the balance of nature itself.
From polar ice to beaches to the open ocean, Basilosaurus is a pulse-pounding marine thriller where prehistoric power collides with modern science, and the sea remembers its most ancient ruler.
