When a deadly virus sweeps through Harmony Falls, Andrew's family finds refuge in an underground bunker. But as the world crumbles, it's not the virus that turns people into mindless, rage-filled killers - it's the vaccine they're told will save them.

Together, they teach each other skills that might be the key to surviving. But with his younger sister Lilly's life on the line, Andrew must decide. Can Bella's toughness help him shield his family, or will his need to protect them be his downfall?
