As far as Riley McCullough is concerned, her best friend getting 'dragged' off to Puerto Vallarta for the first two weeks of summer vacation was the end of the world―at least until the bombs fell. Life in suburban New Jersey with her mother has been comfortable, not to mention boring, to an introverted fourteen year old. As if her friend's surprise trip wasn't bad enough, her expectations for the 'best summer ever' disintegrate when she gets sent across the country to stay with a father she hasn't seen in six years. Adjusting to a tiny, desert town where everyone stares at them like they don't belong proves difficult, and leaves her feeling more isolated than ever. To make matters worse, her secretive father won't tell the truth about why he left―or what he's hiding. Her luck takes an unexpected turn for the better when she meets a boy who shares her interest in video games and contempt for small town boredom. In him, she finds a kindred spirit who might just make the middle of nowhere tolerable. Happiness is short lived; fleeing nuclear Armageddon, she takes shelter with her dad in an underground bunker he'd spent years preparing. After fourteen days without sun, Riley must overcome the sorrow of losing everything to save the one person she cares about most.
