Hmm. So many possibilities. Norstrilia, by Cordwainer Smith, for the beauty of the language and the deranged genius of its world building.Roadside Picnic, by Boris and Arkady Strugatsky, for its vision of the unknowable embedded in the practicalities of modern life. The Big Time, by Fritz Leiber, serious contender for best time travel story ever, unfolding the fate of the work within a two-room R&R station. Star Maker, by Olaf Stapledon, unfolding the entire history of the universe and beyond, with a chilly vision of who makes it that retains compassion for individuals.
