Cassandra Kline is taken in by Pyramid Corporation in the midst of global nuclear war. For the next five years, she lives safely inside a protective domed city.
Working in The Program, a virtual reality simulation, she is confronted by her dead mother who tells Cassie she is in danger. After a shocking revelation about the people who she believed had saved her, the hologram of her mother leads her out of the dome and into a toxic, dead world.
Rafe, the alpha of a mutant werewolf pack, takes her in and helps her come to terms with the new world they share.
With zombie attacks, alien spaceships paroling the skies, and the ever-present struggle to survive, will Cassie and Rafe realize their budding attraction? Or will they be torn apart, body and soul.
