T. Kingfisher has a gift. Not just for horror, not just for wit, but for writing books that make you simultaneously squirm and grin and immediately recommend to your most unsuspecting friends. Her latest, Wolf Worm, released this week on March 24, might be her finest work yet. If you like books that demand to be read, check out our take on why Project Hail Mary is a must-read before its film adaptation. And yes, the title is exactly what you think it is.
A Scientific Illustrator, a Creepy Manor, and Way Too Many Insects
Wolf Worm is set in 1899 North Carolina, which already sounds like a gothic horror painting before you add a single plot point. The protagonist, Sonia Wilson, is a scientific illustrator left without work or prospects after her father’s death. When a reclusive entomologist named Dr. Halder offers her a position documenting his enormous insect collection at his remote manor house, Sonia takes the job. She doesn’t ask too many questions. That turns out to be a problem.
Kingfisher, who writes under a pen name (she’s actually Hugo- and Nebula Award-winning author Ursula Vernon), has built her reputation on horror that is warm, funny, and deeply unsettling all at once. For another author doing genuinely weird things with non-human minds, Tchaikovsky’s Children of Strife puts a mantis shrimp in command of a research vessel — and it works. Think: the kind of book where you laugh out loud in one paragraph and feel your skin crawl in the next. Wolf Worm continues that tradition while raising the bar considerably on the “disgusting” front. The New York Times called it that, approvingly. The author herself would probably agree.
What Makes It Work
Horror lives or dies on its protagonist. You need someone worth following into the dark, and Sonia Wilson earns that role immediately. She’s a Darwinist and naturalist whose sharp observational mind filters every person, landscape, and specimen through an artist’s eye. This means Kingfisher communicates character entirely through perspective, not through exposition. You don’t get told that Sonia is clever. You see it in what she notices.
Dr. Halder, the eccentric entomologist, is rendered with equal precision. Early in the book he delivers this gem: “Cleanliness is next to godliness, Miss Wilson, or so they say. But foulness provides rather more opportunity for scientific inquiry.” This is the kind of line that should be embroidered on throw pillows in every biology department in the country.
The horror builds slowly. Strange animal behavior. A shed with no business having a basement. Local whispers about blood thieves in the woods. A lantern moving through the dark. Kingfisher understands something that a lot of contemporary horror writers seem to forget: dread accumulated quietly is far more effective than shock. She deploys humor strategically to lower your guard, then pivots back to the unsettling. By the time the book goes full body horror, you’re in too deep to escape.
The Actual Bugs (You’ve Been Warned)
Fair warning: this book contains screwworms, botflies, wolf worms (obviously), and a general parade of parasitic insects that will rearrange how you feel about nature. Kingfisher’s research is so deep and specific that readers are left debating whether this is her secret lifelong obsession or extraordinarily thorough homework. Either way, it works. You come away from Wolf Worm knowing things about parasitic larvae that you cannot unknow. One early reviewer reported considering a full beekeeping suit for any future travel to Central or South America.
What’s remarkable is that none of this becomes gratuitous. The entomology serves the story, not the other way around. Insects were genuinely sinister scientific territory in 1899 North Carolina, before modern understanding of parasitology, and Kingfisher uses that period-accurate ignorance to maximum effect. The folklore element, involving local legends about “blood thieves,” weaves through the biology in a way that feels organic rather than tacked on.
Southern Gothic Done Right
The setting is more than backdrop. Kingfisher lived in North Carolina for years and it shows. The 1899 rural South is rendered with care, specificity, and authenticity that feels lived-in rather than researched. The local folklore carries genuine weight. The class dynamics and social constraints on a woman working in scientific illustration during this era are handled with a light touch that never becomes a lecture.
If you’re going to read this as an audiobook (and the narrator, Mary Robinette Kowal, is herself a North Carolina native), the audio edition is particularly recommended. Kowal’s character voices are distinct, her pacing through the horror sequences is exceptional, and she brings a regional authenticity to the material that printed text simply can’t replicate.
Who Should Read It
If you liked Kingfisher’s What Moves the Dead (the Algernon Blackwood-inspired fungal horror) or A House With Good Bones (Southern gothic meets genuinely awful family dynamics), Wolf Worm is your next read. Same formula: smart protagonist, creepy setting, mounting dread, dark humor, deeply weird biology.
If you’ve never read Kingfisher before, this is actually a solid entry point. It’s a standalone novel, which means no series commitment, just one concentrated hit of Southern gothic folk horror with parasites. You can decide whether to go back and read the rest of her catalog. (You will.)
If you’re strongly averse to body horror or insects, maybe start with something else. Kingfisher is generous with her warnings, and the book earns its “disgusting” descriptor. The author’s note at the end is worth reading regardless, because she discusses the personal origins of the novel with characteristic honesty, and it reframes the whole book in a surprisingly affecting way.
The Verdict
Wolf Worm is Southern gothic horror at its best. It’s atmospheric, witty, and genuinely frightening in a way that stays with you. The protagonist is compelling, the setting is distinctive, the horror is earned, and the bugs are truly, magnificently awful. The ABQ Journal calls it “one of the most accomplished horror novels of 2026,” and this is not hyperbole.
T. Kingfisher keeps raising her own bar, and with Wolf Worm she’s done it again. If you want proof that horror fiction is in genuinely good hands right now, pick up this book. Just maybe don’t read it while eating.
