In the summer of 1962, the possibility of nuclear war is all anyone talks about. But Scott's dad is the only one in the neighborhood who actually builds a bomb shelter. When the unthinkable happens, neighbors force their way into the shelter before Scott's dad can shut the door. With not enough room, not enough food, and not enough air, life inside the shelter is filthy, physically draining, and emotionally fraught. But even worse is the question of what will -- and won't -- remain when the door is opened again.
