Casey Pearson grew up with a doomsday-prepping father. At eighteen, tired of living an unconventional life, she left home, vowing never to return.

More than a decade later, a mysterious viral outbreak changes everything, including the people it infects, turning them into zombielike creatures. It's the end of the world, and no one saw it coming-well, except for Casey's father. With no place left to run and danger lurking around every corner, Casey is forced to return home.

Upon arrival, she's surprised to find that her dad has hunkered down with a group of survivors, including her archnemesis, Blake Morrison, the high school bully who made Casey's teenage years a living hell.

While struggling to live on the compound, face outside threats, and survive alongside her handsome enemy, Casey will learn that although the world has ended, hers is just beginning.
