The Mermaid Astronaut by Yoon Ha Lee (Beneath Ceaseless Skies #298, 27th February 2020)1 has a title that pretty much describes the story: a mermaid called Essarala wants to travel among the stars but lives in a planet-bound culture. Then, when an interstellar trading ship arrives in orbit for the first time, Essarala thinks she may have found a way off-planet—until she realises that the ship has no water for a mer to live in. Her sister Kiovasa suggests they should visit the witch beneath the waves for help.
After arriving at the witch’s lair, and discussing the matter with her—during which the witch gives warnings about the dangers and difficulties that will lie ahead—she says that she can give Essarala two legs like the humans. Essarala is determined to go and, even though she doesn’t understand everything the witch has warned her about, asks what the price is. The witch replies that one day Essarala will want to come home and, when she does, she should visit her again. Then the witch gives her a knife that will cleave her tail into two legs.
Later, after Essarala has cut herself and been accepted onto the crew, she is given to an alien called Ssen to be mentored. We see her develop as a crew member, and learn about some of her adventures:
Essarala learned to fly in skysuits in vast and turbulent gas planets, some of which had corrosive atmospheres. She saw twin sunsets over methane seas and meteor showers flung across brilliantine nighttime skies. She walked through forests of towering trees sharded through with crystal and breathed in the fragrance of flowers that bloomed only once a millennium. And she kept her promise, too: for every world she visited, she sang her sister’s name.
Someday I will go back and tell her of the things I have seen, Essarala thought again and again. But not yet, not yet.
Then, towards the end of the story (spoiler), Ssen teaches Essarala about special relativity, and she realises that time will be passing much more quickly for her sister on her world. Essarala begs the captain and crew to take her back home, and they generously do so. As soon as they arrive Essarala visits the witch as promised, to be told that the old woman will shortly die and that, given the wisdom she has gained on her travels, Essarala will replace her . Then the witch tells Essarala that her sister is still alive but that she doesn’t have long left. Essarala goes to find her, and the story ends with the two sisters together.2
I thought the idea of telling an SF story as a fantasy tale worked very well here (it’s possible to view the severing of her tail to become two legs, etc., as unexplained superscience), and it is an enjoyable and original piece. I also thought Lee’s elegant and concise writing style added to the story. The ending is perhaps not as strong as the rest of it, but that is a minor quibble.3
***+ (Good to very good.) 5,950 words. [Story]
1. This is a finalist for the Sturgeon and short story Hugo Awards for 2021.
2. There is a dedication at the end of the story to Lee’s sister.
3. Some of the commenters in one of my (private) FB groups (The Best Science Fiction and Fantasy Short Fiction) thought that the lack of foreboding at the end of the story was a weakness. I thought that the uncertainty about her sister provided that.
