There's something in the water...but this time, it's not what you think it is. The master of the deep now gives us a stunning, brilliantly suspenseful novel about a strange new predator of the sea. At a small marine institute off the coast of Connecticut, a young marine biologist, Simon Chase, studies and tracks sharks, whales, sea lions, and a vast array of other marine species, as well as the effects of pollution and other threats to ocean's environment. He begins to notice strange behavior among the creatures of the sea; something in the ocean is throwing off the balance of nature. Then the body of a diver washes ashore. When more victims are discovered, Chase realizes that while the killer resembles a white shark, it is far more dangerous and malevolent than any shark he has encountered before.
