The end of the second millennium witnessed an increase in science-fictional apocalyptic narratives globally. There is a noteworthy difference between such fictions from Latin America and the anglophone world and those from Spain, in which scientific explanations of events coexist with biblically-inspired plots, characters and imagery. This is the first book-length study of either science-fictional novels or apocalyptic literature in that country, analysing six such works between 1990 and 2005. Within a theoretical framework that includes critical and genre theories, archetypal criticism, and biblical scholarship, the book explains this phenomenon as a result of three historical factors: the 'Two Spains', Spanish 'difference', and the 'Pact of Silence', a tacit agreement that made justice and accountability impossible in the name of a peaceful transition to democracy. It repressed any processing of the historical trauma experienced during the Civil War and dictatorship, trauma that manifests itself symbolically in these fictions.
