Level 7 by Mordecai Roshwald

Set in a dystopian future, the narrative follows a soldier known only as X-127 who is assigned to a deep underground bunker, Level 7, designed to withstand nuclear warfare. As part of a select group responsible for launching retaliatory nuclear strikes, X-127 grapples with the psychological and moral implications of his role in a world on the brink of annihilation. The story unfolds through his diary entries, revealing the isolation, despair, and eventual realization of the futility of their mission as the surface world succumbs to the catastrophic consequences of nuclear conflict.
