Sixteen-year-old Paige has one chance to escape an arranged marriage to a boy in her post-apocalyptic cult: by becoming its human sacrifice. In that role, the souls of her neighbors rest in her hands, but she's starting to doubt her ability to deliver them to the afterlife. Not when she doesn't know what to do with the inappropriate sexual attraction she's feeling toward another girl-her best friend, Mott. Not when Paige knows she's not pure, that they chose the wrong girl.

When her brother gets himself arrested and Mott follows suit, Paige finds her beliefs crumbling. Powerless to help them directly, she joins a resistance group and takes on the unthinkable: assassinating the religion's leader. Caught between bad and worse, Paige must choose between the strict, zealous love their religion preaches, or fighting for the freedom to search for her own version of "home"-even though she might never find it.
