I really can’t say anything about my thoughts on Utriusque Cosmi by Robert Charles Wilson without massive spoilers. Consider yourself warned!
I read this story as What Do You Do? by Gillian Flynn in Rogues, edited by Gardner Dozois and George R.R. Martin. It was later republished as The Grownup.
This is full of spoilers for this short story. If you haven’t read it yet, then don’t read this article. Unless you like spoilers. And speaking of spoilers…
I’ll fully admit to being fairly self-absorbed, but fiction with a writer as its protagonist generally doesn’t interest me. The Lady With the Light by Mel Kassel was a pleasant and disturbing surprise.
Warning: I’m going to be thoroughly spoiling this excellent and unsettling short story.
Naomi Kritzer’s Cat Pictures Please is the only story I can think of that has ever terrified and me and given me hope at the same time.
Very mild spoilers follow.
