    Remember what a wild frontier the early days of home gaming were? Manufacturers releasing new consoles at a breakneck pace; developers creating games that kept us up all night, then going bankrupt the next day; and what self-respecting kid didn't beg their parents for an Atari or a Nintendo?

Passing evacuees told of a safe haven in the mountains, but her father refused to leave. He thought their home was safe… until a gang of looters kicked in the door. Four years ago at thirteen, Harper won trophies for competition shooting, but killing a man pointing a gun at her is nothing like nailing targets at a range. Hesitation cost her parents’ lives. With no other options, she grabbed her little sister and ran away from the only home she’d ever known into a world she no longer recognized. The promise of safety in Evergreen gives her hope, but unless the girl voted sweetest in her class can find the nerve to kill, Harper—and her kid sister—are as good as dead.
