Multiple masterpieces of science fiction from a Hugo and Nebula Award-winning author in one volume. From a master of the Golden Age of science fiction, this collection includes:   Way Station:Enoch Wallace lives a secluded life in the backwoods of Wisconsin. He carries a nineteenth-century rifle and never seems to age--a fact that has caught the attention of prying government eyes. The truth is Enoch's the last surviving veteran of the American Civil War, and for close to a century, he has operated a secret way station for aliens passing through on journeys to other stars. But the gifts of knowledge and immortality that his intergalactic guests have bestowed upon him have opened Enoch's eyes to humanity's impending destruction.   Time and Again: Twenty years ago, Asher Sutton vanished in the star system 61 Cygni. Now, he has returned to Earth, but the star-traveler is no longer completely human--and he has a message to convey that could have reality-altering consequences for the human galaxy. It's Asher's destiny to change everything, but it could make him a target for time-traveling assassins whose mission it is to silence him at all costs.   Good Night, Mr. James: Beginning with the title story--a wry and chilling horror tale about cloning and alien invasion that inspired The Outer Limits episode "The Duplicate Man"--Clifford D. Simak's essential collection of strange, poignant tales of life on tomorrow's Earth and in outer space invites readers into worlds of wonder and imagination that represent literary science fiction at its very best, and prove the author a genre master.
