A collection of 20 classic short stories by Isaac Asimov, author of the Foundation series, featuring the definitive and only in-print version of “Nightfall”.

The colony on Haven-7 has gone rogue. The colonists have split into two factions: the Techborn and the Dusters. The Techborn have always ruled the planet. They control the remnants of the crashed starship that brought humanity to this new world. The Dusters… they eat Techborn dust. Now, the Techborn strength is waning. Their weapons are getting old, and radiation leaks from the aging reactors have created mutations. Some of these, like their brutish troops known as Tuskers, have proven useful—but others are abominations.
