Kept hidden from mankind forever, it is about to surface. 'When it rises up, the mighty are terrified.' After a rash of violent attacks throughout the Caribbean, marine biologist Kelly Andrews captures evidence of an unidentified species of predator in the Atlantic. Something unknown to science, something new altogether . . . or else something very old. 'It makes the depths churn like a boiling caldron and stirs up the sea.' Billionaire Oscar Wright learns of the sea monster's existence, which he considers to be the Biblical Leviathan. Driven mad by grief, the old man devotes his vast fortune to kill the beast for a personal vendetta, harvest its hide as the ultimate trophy. 'Nothing on earth is its equal -- a creature without fear.' Two separate expeditions race across the ocean to find the creature. And when it's finally located, one thing becomes clear: humanity no longer tops the food chain.
