The players call it The Game. There are just two rules:
No killing close to home.
No Killing outside the game

But what happens when those rules get broken?

When the drowned body of a troubled teenager is recovered from a river in Maine's Kennebec Valley, and a young woman disappears from a small rural town, they draw the attention of the private investigator named Charlie Parker.

Now Parker will be forced to confront a band of men without morality and without loyalty, not even to one another, in a place where the very darkness is alive.

Because something has emerged from the shadows, something very bad.

And it wants revenge.
