I never thought I'd live through an apocalypse, but I guess no one ever does. Now my family's gone, and the only person who can keep me safe in a violent, chaotic world is my dead boyfriend's rough, uncivilized father. I don't like him. At all. Cal's the last person I want to rely on, but for now he's all I've got. Eventually we become unconventional partners as we try to stay alive, but then my feelings for him start to change. I want more from Cal but maybe I shouldn't. I can't risk losing what matters most. One thing I do know. In a world as broken as ours, everything gradually gets burned away. Everything but him.
