A scientist stealing across the Pyrenees into Spain, then smuggled into America . . . A young woman quarantined on a ship wandering the Atlantic, her family left behind in Austria . . . A girl playing on a riverbank as a solitary airplane appears on the horizon . . . With these three people, Dennis Bock transforms a familiar story - the atom bomb as a means to end worldwide slaughter - into something witnessed, as if for the first time, in all its beautiful and terrible power. As their fates triangulate, the true costs and implications of a nightmare that has persisted for more than half a century are revealed.
