Apostezjon is social science fiction dystopia trilogy by Polish sociologist and science fiction writer Edmund Wnuk-Lipiński. It consists of three novels, Wir pamięci (1979, "Memory Vortex"), Rozpad połowiczny (1988, "Half-Life", literally: "Half-Decay"), and Mord założycielski (1989, "The Founding Murder"). The overall story covers the dynamics of Apostezjon (from Greek word ἀποστάσιον, "apostasion"), a totalitarian island-state governed by the technocratic clandestine supreme governing body "Team of Experts" with its executive organ, the powerful Special Service, up to its collapse into a dictatorship after a coup staged by the deputy chief of the Special Service.
