“One life should be enough to give for humanity... but humanity wanted Asher Sutton to keep making the sacrifice indefinitely!” TIME QUARRY was the first serialized novel in the GALAXY SCIENCE-FICTION MAGAZINE series, appearing in the first three issues. It accounted for more than half the story pages, and was instrumental in catapulting GALAXY as the mature science-fiction venue, which attracted not only readers, but some of the best writers of the day, including Clifford D. Simak. Simak (1904-1988) was an accomplished Grand Master of SF, winning three Hugo Awards and the Bram Stoker Award for Lifetime Achievement. He was already a member of the SF elite when TIME QUARRY appeared. ALSO AVAILABLE IN HARDCOVER THIS STORY ALSO APPEARS AS PART OF “THE GALAXY SCIENCE FICTION TREASURY: VOLUME 1”.
