Between the Strokes of Night

Between the Strokes of Night (1985) is a science fiction novel by English-American writer Charles Sheffield. It first appeared in the March to June 1985 issues of Analog Science Fiction/Science Fact before being published by Baen Books in July 1985. The story is divided into two vastly separated periods: the near future of 2010, and the far future of 29,000 AD. Owing to the unique technological mechanisms of the novel, the same cast of characters appears in both parts, though it is not a time travel story.
