The Outside In , though undeniably brutal, forges unexpected bonds and strengthens old ones in the unlikeliest of ways. Baylee Phelps, freshly seventeen and expecting nothing more than a few final exams and a summer of freedom, never imagined her last day of school would turn into a nightmare. But when the alarms blare and chaos erupts, she quickly realizes—she might not be going home tonight. Trapped inside with a flesh-eating monster masquerading as a person, Baylee is forced to choose: hide, run, or fight. Survival would be hard enough on her own, but she's not alone.
