Four months to the day he first encountered the boy at Walmart, the last of Phil Pendelton's teeth fell out.

At first glance, Phil Pendleton and his son Adam are just an ordinary father and son, no different from any other. Some might say the father is a little too accommodating given the lack of discipline when the child loses his temper in public. Some might say he spoils his son by allowing him to set his own bedtimes and eat candy whenever he wants. Some might say that such leniency is starting to take its toll on the father, given how his health has declined.

What no one knows is that Phil is a prisoner, and that up until a few weeks ago and a chance encounter at a grocery store, he had never seen the child before. But now Adam is in his life, altering and controlling it, and it will take a particular kind of horror to get him out. Because there is nothing ordinary about Adam, or the monsters that come when he calls.
