Entry to Elsewhen is a collection of science fiction short stories by John Brunner, published in 1972. It contains the following stories: "Host Age" first appeared in New Worlds in 1955. "Lungfish" first appeared in Britain in Science Fantasy in 1957. "No Other Gods But Me" first appeared in what the acknowledgments page of this book describes as a "shorter and substantially different form" as "A Time To Rend" in Science Fantasy in 1958. The version included in Entry to Elsewhen was written in 1966 and first appears in this collection. The above attributions notwithstanding, the book's acknowledgments page notes that "All three stories have been completely revised by the author for the present book." Host Age The first story takes place in what appears to be the relatively near future. Set in London, it deals with the appearance and spread of a mysterious new plague. The plague defies all efforts to treat it or stop its spread, showing varied symptoms in different victims and mutating rapidly. A sinister aspect soon appears when scientists making progress in fighting the plague are repeatedly sabotaged by unknown persons. Also, the plague seems to be spread by multiple typhoid Mary individuals, found unconscious on trains with large amounts of cash but no identifying information. Eventually it is discovered that the plague is being spread by human military forces who have travelled through time from several centuries in the future. The head of this group explains that the plague was developed by an aggressive alien species with the purpose of destroying humanity. The plague's effectiveness derives in part from atrophied immune systems resulting from long-term prevention of exposure to any infectious agent. Traveling to the past is a desperate measure to introduce the virus to humans with more robust immune systems in the hope that the survivors will be better able to resist the virus when the alien species creates it. Lungfish This story takes place aboard a multi-generational spaceship travelling from Earth to a planet orbiting Tau Ceti with the goal of establishing a colony. The story's action concerns the end of the journey. The trip has taken 37 years, and by now the crew is composed of two groups—the Earthborn, the surviving members of the original crew, and the Tripborn, descendants of the original crew, who have lived their entire lives aboard the ship. On reaching the destination planet, the Tripborn refuse
