In this captivating climax of the acclaimed trilogy about one suburban neighborhood's survival after a global blackout, teenager Adam Daley has been forced to kill again. It had to be done, and part of him knows that. But murder changes a person. It can certainly change a kid who's already grown up too quickly and too harshly in the wake of a catastrophic global shutdown four months ago. In the name of safety and survival, Adam and his neighbors have turned their Middle American community into a fortress, defending against countless enemies. However, what's lurking in the dark is a greater danger than ever before: somebody who wants to destroy the neighborhood 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. Sometimes even the dark is not cover enough to hide things that would never happen in the light.
