Kenny Farlow and the other developers of the nuclear fallout shelter never imagined they would be hopelessly trapped within their own creation. The day the bombs fell, the vault shut them in underground, refusing to open. This would be the ultimate test of the very systems they had designed. After a year and a half, they had mastered living underground, and they had learned to survive and cope with the idea of never seeing the sun again. But they never stopped trying. In the middle of a fatal system malfunction that shuts off their life support, Kenny faces the most dramatic moral challenges of his life as he fights for survival against the very people that were as his own family mere moments before. And in a conspiracy laced glitch, he and he alone manages to escape the vault. Electrical storms, irradiated food and water, and deadly mutated beasts become the least of his worries as Kenny navigates through this kill or be killed world. With violent, self-serving militias in control of this new world, the rules of right and wrong are no longer what they used to be. Kenny's own primal instincts threaten to consume him, making him more like them than he is comfortable with.
