Adam has killed again. It had to be done, part of him knows that, but murder changes a person. It can certainly change a teenager who's already grown up too quickly, too harshly, in the wake of the catastrophic global blackout five months ago. In the name of safety and survival, Adam and his neighbours have turned their middle American suburban neighbourhood into a fortress, defending against countless enemies. But what's lurking in the dark is a greater danger than ever before: somebody who wants to destroy the neighbourhood and Adam at any cost. Soon, the hunted will have to become the hunter . . . and Adam hates himself for what he will have to do. Because sometimes even the dark is not cover enough for things that would never happen in the light.
