It Kills. . . On a hot summer night in Montauk, the bodies of two local bar patrons are discovered in the dunes, torn to shreds, their identities unrecognizable. . . It Breeds. . . In another part of town, a woman's backyard is invaded by four terrifying creatures that defy any kind of description. What's clear is that they're hostile—and they're ravenous. . . It Spreads. . . With every sunset the terror rises again, infecting residents with a virus no one can cure. The CDC can't help them; FEMA can't save them. But each savage attack brings Suffolk County Police Officer Gray Dalton one step closer to the shocking source of these unholy creations. Hidden on nearby Plum Island, a U.S. research facility has been running top-secret experiments. What they created was never meant to see the light of day. Now, a vacation paradise is going straight to hell.
