Morning Child, by Gardner Dozios

Morning Child is another war story, I think a theme for the collection it is in.  The weapons are fantastic, but they have passed beyond understanding.  Williams and John pass their days in a depopulated post-apocalypse world, near the ruins of their old home.

To describe the story further would be to fully quote it.  It's pretty short, nominated for a Nebula Best Short Story in 1984.  It's a good short story--the relationship brings out what has happened to them, not any sort of exposition.  Except toward the end, where it adds poignancy.  Read it to fill a few minutes.  Three stars, kind of by default.
