Timescape

Timescape is a 1980 science fiction novel by American writer Gregory Benford (with unbilled co-author Hilary Foister, Benford's sister-in-law, who is credited as having "contributed significantly to the manuscript"). It won the 1981 Nebula and 1980 British Science Fiction Award, and the 1981 John W. Campbell Memorial Award for Best Science Fiction Novel. It won the 1981 Ditmar Award for Best International Fiction. The novel was widely hailed by both critics of science fiction and mainstream literature for its fusion of detailed character development and interpersonal drama with more standard science fiction fare such as time travel and ecological issues. Pocket Books used the title of this book for their science fiction imprint, Timescape Books.
