Time and Again (Clifford Simak, 1951)

Time and Again opens in a distant future on earth that includes androids, robots, interactive television, weather control, mentophones - an ingenious device that allows instantaneous interstellar communication, dramatically extended life spans, travel to distant star systems and a humanity that has conquered the galaxy and spread its seed far and wide. After a 20 year absence, Asher Sutton returns to earth from an expedition to 61 Cygni, a system that until now has defeated every attempt at landing and exploration. In the attempt, Sutton has miraculously survived a crash that left his ship disabled and, by all odds, should have killed him. His ship has somehow managed to return to earth apparently without the actual ability to do so and Sutton, through some extraordinary feat of bio-medical engineering, appears to have been modified into something that is considerably less than completely human. He is mentally linked to someone he refers to as "Johnny". The administration on earth wonder what all of this can possibly mean...

Way Station (Clifford Simak, 1963)

Its hero Enoch Wallace first appears as a mystery man: an impossibly young-looking Civil War veteran, 124 years old and still living in his parents' remote Winconsin farmhouse. Nowadays this building has a glittering, Tardis-like interior, ever since Wallace was recruited by aliens as stationmaster on a minor branch line - not a railway, but Galactic Central's network of matter transmitters carrying passengers between the stars. Earth isn't ready for this secret, and countryman Wallace's best friends are extraterrestrials and ghostly simulations.

When the CIA investigates his reclusive lifestyle, it accidentally stirs up an interstellar diplomatic crisis. Wallace's job, and his place in the countryside he loves, are suddenly threatened. So are his hopes for persuading Galactic Central to step in and halt our accelerating slide towards nuclear war.
