On Kalgash, a planet perpetually illuminated by six suns, its inhabitants have never known darkness or the sight of stars. When the suns begin to set, plunging their world into an unprecedented twilight, civilization teeters on the brink of collapse. As scientists grapple with the impending astronomical event, religious fundamentalists predict an apocalypse, while a primal, collective fear of the unknown night grips the populace. This expanded novel, born from Isaac Asimov's legendary short story and co-written with Robert Silverberg, explores humanity's psychological response to a world-altering disaster.
