The best fantasy is about what is lost and gone, but surprisingly some of the most moving science fiction is too.
I just re-read Michael Flynn’s story “Melodies of the Heart” in the collection The Forest of Time. It’s about, oh, a little girl who is growing old too fast and an old dying woman who is remembering melodies from deeper and deeper into the past. The 50s, the 20s, the Gay Nineties. It is a hard story to bear.
I seek no more the fine and gay,
For each does but remind me
How swift the hours did pass away
With the girl I left behind me.
