I found the conception of the Apocalypse in Samuel Delaney's Stars in My Pocket Like Grains of Sand the most interesting part of the book. Delaney's idea of how worlds end is so different from other books and from popular thought. For one thing, it is not really an Apocalypse, an end of days -- life, and culture, goes on even after a world has been destroyed by that enigmatic thing, the Cultural Fugue. Secondly, the world does not end by asteroid collision, or by a trigger-happy country with too many nuclear warheads but by information, and by culture.
