Issac Asimov & Robert Silverberg - Nightfall

"Nightfall," co-written by Isaac Asimov and Robert Silverberg, is an expanded novelization of Asimov's classic 1941 short story of the same name. The story is set on the planet Lagash, which experiences perpetual daylight due to its six suns. The inhabitants of Lagash are on the verge of a once-in-millennium eclipse that will plunge their world into complete darkness for the first time in living memory. The novel delves into the psychological and societal implications of this impending catastrophe, as the inhabitants have never known night and are ill-prepared for the overwhelming darkness.

As the eclipse approaches, a group of scientists races against time to understand the nature of the impending disaster and to warn the population. Their efforts are met with skepticism and resistance from both the public and the ruling authorities. The narrative explores themes of fear, ignorance, and the fragility of civilization, illustrating how a society accustomed to perpetual light reacts to the unknown and the unseen. Asimov and Silverberg's collaboration expands on the original short story, adding depth to the characters and the world of Lagash, while maintaining the core philosophical questions about knowledge, belief, and the human condition.
