This involves many different aspects and dimensions, each of which requires different approaches. It arranged to reflect the different levels of analysis involved in the poetics of science fiction. The book discusses the presentation of dated futures in science fiction and tackles the interaction of language and science fiction directly, by focusing on those texts that are concerned to manipulate style in an unusual or mimetic way.
