NATIONAL BEST-SELLING AUTHOR. A snow storm of epic proportions shuts down the town of Sheridan, Michigan. The weather is dangerous enough on its own, but it has loosed something even deadlier onto the town: a duo of sadistic killers.

No one thought much about the storm. Not the National Weather Service and not the big-name meteorologists. Experienced local weatherman Wally Wellman thought there might be trouble, but even he couldn't predict the natural disaster that was about to lay siege to the quiet suburb of Sheridan, Michigan.
