A World Out of Time is a science fiction novel by Larry Niven and published in 1976. It is set outside the Known Space universe of many of Niven's stories, but is otherwise fairly representative of his 1970s hard science fiction novels. The main part of the novel was originally serialized in Galaxy magazine as "Children of the State"; another part was originally published as the short story "Rammer". A World Out of Time placed fifth in the annual Locus Poll in 1977. Source: Wikipedia (en)
