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.
