7 Sci-Fi and Fantasy Mermaid Books for Under-the-Sea Reading

Dive into tales of deep-sea cities and mysterious sirens. 

Vampires and werewolves have had their moment alongside any number of other mythical creatures in fantasy in the past two decades, but mermaids have (forgive me) floated along under the radar. But no longer—here are seven of our favorite sci-fi and fantasy mermaid stories.

Buy The Deep at Amazon

The Deep

By Rivers Solomon with Daveed Diggs, William Hutson, and Jonathan Snipes

The experimental hip-hop group Clipping was already on the radar of many sci-fi and fantasy fans when they were nominated for a Hugo for their 2017 album Splendor & Misery. “The Deep,” a song from that album, imagined an aquatic world where the children of enslaved pregnant African women thrown overboard from slave ships were born breathing water instead of air. From that indelible track came this gripping novella about Yetu, the mermaid historian tasked with being her people’s memory-keeper. But with memory comes pain, and when that pain becomes too much, Yetu ventures up to the surface world, where she learns more than she ever could have imagined about her people’s history - and their future. It’s a touching and elegant story about diaspora, inherited trauma, and culture.

Mrs. Caliban

By Rachel Ingalls

If you loved The Shape of Water, you’d be remiss not to seek out Mrs. Caliban, a surreal gem of a novel first published in 1982. In mid-century America, Dorothy is languishing. Her pregnancy ended in miscarriage, her dog was struck and killed by a car, and her husband is cheating — again. Enter Larry, a tall, dark, and handsome seven-foot-tall frogman. Larry’s escaped from the local oceanographic institute, where he was imprisoned and tortured after being kidnapped from his home deep within the Gulf of Mexico. Both healing from trauma, Larry and Dorothy fall for each other immediately, recognizing in each other the same pain and longing they feel themselves. But Larry is wanted for murder — how long can Dorothy hide him before the world comes calling?

Buy Silver Birch, Blood Moon at Amazon

Silver Birch, Blood Moon

By Ellen Datlow and Terri Windling

Ellen Datlow is a towering figure in the dark fantasy and horror world, curating the best of the best of short fiction into themed anthologies that are surprising, haunting, and engrossing. In Silver Birch, Blood Moon, the fifth in a series, Datlow and co-editor Terri Windling turn their attentions to fairy tales, those oft-sanitized and Disneyfied stories we think we know so well. While the original stories were often quite dark, the reimaginings in this volume are darker still. Contributors include Neil Gaiman, Patricia Briggs, Nalo Hopkinson, Tanith Lee, and Robin McKinley, but it’s Melissa Lee Shaw’s “The Sea Hag” that will catch any mermaid enthusiast’s attention — it’s a retelling of The Little Mermaid, from the sea witch’s perspective, which, as you might imagine, is not what they wrote down in the story books.

The Shape of Water

By Guillermo del Toro and Daniel Kraus

This is so much more than just a novelization of Guillermo del Toro’s acclaimed movie. When Daniel Kraus told del Toro his idea for a story about a monster in a lab, the director was immediately interested. The pair came up with a novel approach to telling this story: they agreed on the basic beats and plot points, and then each developed their own version independently, Kraus for the page and del Toro for the screen. The result is a book with a plot that will be recognizable to fans of the film, but with significant differences: the villain of the film is a hero in the novel, many secondary characters have expanded roles here, and the creature’s backstory is explored in a way the film didn’t really touch. It’s a fascinating approach and an object lesson in how different people tell the same story.

Buy Into the Drowning Deep at Amazon

Into the Drowning Deep

By Mira Grant

A terrifying, sci-fi take on mermaids from Seanan McGuire, writing as Mira Grant. Years ago, the research ship Atargatis was lost at sea, leaving behind only some deeply disturbing video footage (the doomed voyage of the Atargatis is the topic of the prequel novella Rolling in the Deep, which fans of this novel will want to seek out). Now, a new crew is setting out in search of answers: what happened to the Atargatis? What did they find in the endless waters above the Mariana Trench? And, most importantly for scientist Victoria Stewart, what happened to her sister, who was aboard? But truth comes at a price, and these sailors may not like what they find waiting for them out in the vast Pacific.

Buy The Mermaid at Amazon

The Mermaid

By Christina Henry

Christina Henry has made a name for herself writing very dark reimaginings of traditional fairy tales, but The Mermaid is a bit lighter than her usual fare. This fantasy-inflected historical romance features Amelia, an adventurous mermaid who falls in love with a fisherman and gives up her life at sea to live with him on land. When he doesn’t return from a fishing trip one day, Amelia finds herself alone again—until P.T. Barnum arrives at her door, having heard the stories of the mermaid who lives on the hill by the sea. Amelia agrees to join his show as his star mermaid, but what she sees of the world makes her reconsider her participation. Barnum, however, won’t let go of her that easily. This is an entrancing and romantic story, perfect for anyone who loved The Golem and the Jinni.

If you’re in the mood for more of a mermaid sampler platter (sorry), seek out The Penguin Book of Mermaids. It’s an anthology of folk tales about mermaids from around the globe, many of which are published here in English for the first time. These stories span continents and oceans and centuries, from Greek sirens and Scottish selkies to the indigenous Hawaiian m’o and both sirenas and litao from the Philippines. Through these 60+ stories, readers can discover how different cultures and peoples have approached mermaid stories throughout history—of particular note here is the way in which neighboring societies tell the same story with their own peculiar touches.
