"One Flu Over the Cuckoo's Nest," by Kathy Krevat, in Crossing Borders, edited by Lia Brackmann and Matt Coyle, Down and Out Books, 2020.
Timing is everything, so they say.
I'm sure the editors and author of this book had no idea what was heading at them when this book came out in February. You see, the narrator of the very first story is a sentient virus. Specifically an influenza bug.
The virus travels to a nursing home because it is scheduled to kill an old woman who lives there, but someone has already done that. The virus, out of curiosity, tries to discover the killer. It has certain abilities: like a lie detector machine it can detect changes in body patterns that might indicate deception. And it can influence people in subtle ways...
A truly unusual story.
