A writer in California. A doctor in Boston. A motel owner and his employee in Nevada. A priest in Chicago. A robber in New York. A little girl in Las Vegas. They’re a handful of people from across the country, living through eerie variations of the same nightmare.

In picturesque Moonlight Cove, California, inexplicable deaths occur, and spine-tingling terror descends to this "edge of paradise". Growing numbers of residents harbor a secret so dark it is sure to cost even more lives.

They found the town silent, apparently abandoned. Then they found the first body strangely swollen and still warm. One hundred fifty were dead, 350 missing. But the terror had only begun in the tiny mountain town of Snowfield, California.

Enter the world of the Pendleton: The original owner became a recluse - and was rumored to be more than half mad - after his wife and two children were kidnapped in 1896 and never found.

Craftsmen and laborers working on renovations disappear or go mad.... For years, the Pendleton is a happy place, until a bad turn comes again.... Voices in unknown languages are heard in deserted rooms....

Although an air of menace hangs over these men, an infinitely greater threat has arrived, one so strange even the island animals are in a state of high alarm.
