From USA Today bestselling author Cassandra Khaw comes The Salt Grows Heavy, a razor-sharp and bewitching fairytale of discovering the darkness in the world, and the darkness within oneself.

“Narrator Susan Dalian viscerally conveys the gruesome body horror while deftly capturing the lush imagery.”—Library Journal

“This brilliant novella is not to be missed.”—Publishers Weekly, STARRED review

You may think you know how the fairytale goes: a mermaid comes to shore and weds the prince. But what the fables forget is that mermaids have teeth. And now, her daughters have devoured the kingdom and burned it to ashes.

On the run, the mermaid is joined by a mysterious plague doctor with a darkness of their own. Deep in the eerie, snow-crusted forest, the pair stumble upon a village of ageless children who thirst for blood, and the three “saints” who control them.

The mermaid and her doctor must embrace the cruelest parts of their true nature if they hope to survive.

A Macmillan Audio production from Tor Nightfire.

Critic reviews

“Devastatingly effective…a folklore-infused world that feels wholly unique. Expertly blending a gothic atmosphere with elements of splatterpunk, this brilliant novella is not to be missed.”—Publishers Weekly, STARRED review

“A feverishly gory, grotesquely beautiful and baroque fairy-tale-meets-love-sonnet. Cassandra Khaw’s imagination is limitless.”—Paul Tremblay, author of The Cabin at the End of the World and A Head Full of Ghosts

“Cassandra Khaw’s writing is never more lyrical than when they’re describing the knife in your heart. The bones of a fairy tale sunk deep in a charnel house of descriptive prose, an elegant confection with a blood-soaked core. I devoured it in one sitting.”—T. Kingfisher, multi-award winning author of What Moves the Dead and Nettle & Bone

Featured Article: The top 100 horror books of all time


This list encompasses the full spectrum of what horror can be—campfire-worthy tales, stomach-churning gore, and incisive social commentary. The classics are accounted for, but it also spotlights more recent titles, because that’s the nature of the genre—it is as perennial as it is ever-evolving, conjuring whatever frights most haunt our collective consciousness. Each title does have one thing in common: It makes for devilishly good listening. So cut the lights and press play—if you dare.

Wish there was more to this interesting premise. Ending feels rushed but I truly loved these characters. I am torn.

Fairytale type stories aren’t really my thing usually, but Cassandra Khaw is good. Real good. So, I gave it a go and am glad I did because I really enjoy her work. She has a poetic prose about her. Elegant with the lurking possibility of the grotesque.

The Salt Grows Heavy is a very good lyrical fairytale with a lot of heart. And the appropriate amount of viscera and violence. Very nicely done.

I loved this book, I loved the main characters and the way they were written.

Mermaids, but way more interesting.

The interweaving of fairy tale, folklore, and horror was intricate and fascinating. I would compare this very favorably to Mira Grant’s Rolling in the Deep series, both are well written with excellent plot and setting and of course best of all murder mermaids.
If you are a fan of horror and enjoy folklore and fairy tales you can’t go wrong with this brilliant interpretation of The Little Mermaid.

Glorious gory retelling of a classic
