In a quiet neighborhood, in the house next door, a family is brutally murdered for no apparent reason. You can't help thinking, It could have been us. And you start to wonder, What if we're next?Promise Falls isn't the kind of community where families are shot to death in their own homes. But how well did Jim and Ellen Cutter really know their neighbors--or the darker secrets of their small town? They don't have to look further than their own marriage to know that things aren't always what they seem. Now the Cutters and their son, Derek, must face the unthinkable: that a murderer isn't just stalking too close to home…but is inside it already.
