Fifteen-year-old Jeremy Barnes would rather watch a zombie movie than shoot a real one, but he has no choice if his family wants to survive the end of the world. Their plan? Drive across the infected United States to a cabin in the Colorado Rockies without a scratch, but their trip takes a complicated detour in the middle of Nebraska when they find Kaylynn, a girl who can handle a baseball bat better than Jeremy can hold a .45 Beretta. And when they stumble into a sanctuary, Jeremy soon learns that Kaylynn is stronger than she looks—a deadly secret lies inside her.
After the radio picks up a distress call from Kansas City about a possible cure, Jeremy’s parents go with a team to investigate. They never return. The only way to find their parents is for Jeremy and his sister Jewel to rely on a dangerous girl who might just turn on them at any moment.
