On the side of an old abandoned building, in an old abandoned shopping center, there is a Mouth.

It's a human mouth; and one that's big enough to drive a car through. It stands open and unmoving, teeth and tongue exposed to the world.

The first people to find it are a bunch of teenagers, among them the Dowel brothers: Freddie and Simon. They're just kids, and the thing about kids is that they're curious and they're reckless. It's not long before the brothers find themselves in the center of a terrible tragedy.

Word spreads. Tempers flare. Fingers are pointed and bonds are broken. In the wake of an awful loss, a community grows sick, and Simon's life begins to crumble apart.

And through it all, the Mouth remains open and unmoving, hungry and waiting. It calls, and one day soon, it will be answered.
