For the children of Burke’s Hollow Middle School, the end of the world came during first period. On a cold, rainy morning, the dead returned to life. Now, the children have lost their families and friends, they’ve been trapped inside the school for weeks, and there are only a handful of adults left to keep the peace. But when a child’s suicide spurs two teachers and a troubled parent to leave in search of supplies, the children find themselves alone, facing something even worse than the dead. After discovering that a teacher has kidnapped a fellow student, two boys, Ian and David, take control of the school in particularly bloody fashion. As the children struggle to survive on their own, tragedy and religious mania will threaten to tear everything apart.
