Cassidy Hart is your typical High School graduate: a little shy, a little sarcastic, and a little naive. But when an electromagnetic pulse takes down the United States, she’s forced to kick into full survival mode when she gets separated from her father. Yeah. Things suck. But with the help of a handsome soldier named Chris, she just might find her dad without getting into serious trouble. Emphasis on might. Oh. And there’s the matter of avoiding getting killed in a world that’s quickly turned into an active war zone. It’s going to change Cassidy’s life. It’s going to be a major pain in the butt.
