Cover designs commissioned by Penguin Random House (DelRey imprint) for the classic short story collection by Isaac Asimov.
The main story ‘Nightfall’ is about a planet that never sees darkness due to being illuminated by at least 1 of 6 suns at any given time. However, every 2000 years a moon obscures one of the six suns—plunging the planet into darkness. Madness, chaos and societal collapse ensue.
