1981’s A Fond Farewell to Dying is a novel-length expansion of Syd Logsdon’s 1978 novella To Go Not Gently.
Of all the nations of Earth, India has been least affected by the Cataclysm that ended Euro-American domination of the world. Though even India was changed: sea level rise has cut it off from mainland Asia and the fallout that made it over the Himalayas has forced birth rates below replacement levels. Two centuries after the nuclear conflict, India is a much emptier place.
Scientist David Singer has abandoned the North America of his birth for India, the most advanced nation on the planet. Now calling himself Ram David Singh, he is researching what he conceives as immortality tech. The odds of an American hick garnering the required resources from the Indian state may seen poor, but geopolitics is his friend.
