A monstrous new breed of rats is taking over New York City in this creature feature horror novel by the author of Jurassic Florida.

New York City's rat population is growing, and Dr. Randolph Finch is determined to solve the problem with his new rodenticide. Degenesis doesn't kill rats—it sterilizes them. But nothing adapts faster than a New York rat . . .

City exterminators Chris and Benita Jackson fear that Degenesis has only made these rats stronger. More aggressive. More intelligent. And far more ravenous . . .

Soon millions of rats are working together as a hive mind in a massive lair beneath Grand Central Station. They feat on the flesh of the homeless population living below—and planning their all-out attack on the unsuspecting humans above . . .
