Seveneves

Neal Stephenson's hard science fiction epic begins with a catastrophic event that renders Earth uninhabitable, forcing humanity to launch a desperate, last-ditch effort to preserve the species in orbit. The narrative then leaps five thousand years into the future, following the descendants of these pioneers as they navigate the complex politics and survival challenges of a spacefaring civilization before attempting a return to a transformed Earth. The novel is characterized by its dense, technical exposition on orbital mechanics and genetics, blending rigorous scientific detail with a sprawling, multi-perspective plot that explores the long-term evolution of human society under extreme constraints.
