Mars, inhabited by mysterious half-humans, half-spirits...Beautiful Venus, which is threatened by a mysterious danger...Earth, turned by mad scientists into an almost Kafkaesque technocratic hell in its power...An innumerable variety of alien cultures, humanoid and non-humanoid...A world in which Arthurian characters coexist with cosmic ones ships, and Christian angels and demons - with representatives of “alien” races... In his “Space Trilogy”, Clive Staples Lewis, for the first time in world literature, combined science fiction, space opera, fantasy and a philosophical parable in one work. And it is precisely this unconditional innovation that provides the novels of the trilogy with a deservedly high place in the history of science fiction.
