Cassandra Khaw was born on 31 August 1984 in Malaysia, and their path to literary horror was anything but conventional. Before novels, there were bylines — games and technology journalism for outlets including Eurogamer, Ars Technica, and The Verge. That background in interactive storytelling left fingerprints all over their fiction: a fluency with atmosphere, dread-as-mechanics, and the particular intimacy of a reader placed inside someone else's nightmare.
Their novella debut, Hammers on Bone (2016), announced a voice that was difficult to categorise and harder to ignore. It folded hard-boiled noir and Lovecraftian cosmic horror into the same bruised, rain-slicked frame, earning a British Fantasy Award nomination and a Locus Award nomination for Best Novella. The follow-up novellas in the Gods & Monsters series continued to push genre conventions sideways, each one a different hybrid of myth and menace.
Then came Nothing But Blackened Teeth (2021), a haunted house story soaked in Japanese Heian-era folklore. A group of friends gathering at a centuries-old mansion, its foundations resting on the bones of a sacrificed bride. Short, suffocating, and precise in its cruelty, the novella became a USA Today bestseller and earned nominations for the Bram Stoker, Shirley Jackson, World Fantasy, and British Fantasy Awards. It is, for many readers, the book that defines what Khaw does best: take something culturally specific, render it with genuine reverence, and then let it turn feral.
The Salt Grows Heavy (2023) arrived with a similar ferocity. A mermaid-and-plague-doctor horror fairy tale that subverts the genre's comfort with deliberate savagery, it demonstrated Khaw's range — moving from Japanese ghost horror to a blood-soaked reimagining of Western folk myth without losing the density of their prose or the sharpness of their thematic concerns. Identity, power, hunger, and the cost of survival run through all of their work like a recurring wound.
Their debut short fiction collection, Breakable Things (2022), gathered 23 stories spanning cosmic dread, body horror, and psychological tension. It won the Bram Stoker Award for Superior Achievement in a Fiction Collection, confirming what short fiction readers had known for years — that Khaw's work in magazines such as Tor.com, Clarkesworld, Uncanny Magazine, The Magazine of Fantasy & Science Fiction, and Lightspeed was not peripheral, but central to their artistic project.
Khaw also co-authored The Dead Take the A Train (2023) with Richard Kadrey, a propulsive urban fantasy horror set in New York City, and their most recent novel, The Library at Hellebore, is a dark academia horror that follows a girl kidnapped and forced into an elite academy for the catastrophically powerful — only for graduation day to become a massacre. It marked their most accessible entry point for readers new to their work, without softening the violence or the wit.
Beyond prose, Khaw has written for video games including Wasteland 3, Sunless Skies, and Fallen London, and contributed to tabletop RPG sourcebooks including Van Richten's Guide to Ravenloft for Dungeons & Dragons. They use they/them pronouns and currently reside in Canada. Across every medium, their writing is governed by the same instinct: to find the seam where folklore, grief, and the body meet, and press on it until something tears.
