Writer Ben Mears has returned to his hometown of Jerusalem's Lot with the hope that moving into a delapidated mansion, long the subject of town lore, might help him get a handle on his life and provide inspiration for a new book. But when two young boys venture into the woods and only one comes out alive, Mears begins to realize that there may be something sinister at work.

In time, he comes to understand that his hometown is under siege from forces of darkness far beyond his wildest imagination. And only he, with a small group of allies, can hope to contain the evil that is tearing the town apart.
