He was sent to kill a pest. Instead, he found a monster.



One of BookPage's Most Anticipated SFF & Horror of Fall 2025

Enter the decadent, deadly city of Tiliard, a metropolis carved into the stump of an ancient tree. In its canopy, the pampered elite warp minds with toxic perfume; in its roots, gangs of exterminators hunt a colossal worm with an appetite for beauty.

In this complex, chaotic city, Guy Moulène has a simple goal: keep his sister out of debt. For her sake, he'll take on any job, no matter how vile.

As an exterminator, Guy hunts the uncanny creatures that crawl up from the river. These vermin are all strange, and often dangerous. His latest quarry is different: a centipede the size of a dragon with a deadly venom and a ravenous taste for artwork. As it digests Tiliard from the sewers to the opera houses, its toxin reshapes the future of the city. No sane person would hunt it, if they had the choice.

Guy doesn't have a choice.

“I will follow this writer anywhere.” —Gillian Flynn, #1 New York Times bestselling author of Gone Girl

“A hallucinatory scorpion sting of a concretized metaphor inhabiting the intersection of Jeff VanderMeer and N.K. Jemisin.” —Elizabeth Bear

An unforgettable ride of a novel from one of my favourite authors working today, this one will swallow you whole and then spit you out changed.” —Freya Marske, internationally bestselling author of the Last Binding series

“Dazzling, elegant, and teeming with a glorious array of monstrosities, The Works of Vermin is at once wonderfully fresh and rotten to its worm-infested core. Loved it!” —Kerstin Hall, author of Asunder

“If you're a fan of Mervin Peake, Gene Wolfe, China Miéville— mammal, have I got a book for you.” —Peter Watts

“Ennes is an alchemist, and The Works of Vermin is its own, new element. A brilliant blend of intense intrigue and the fantastically macabre.” —Johnny Compton, author of The Spite House

“Filled with some of the most twisted, inventive worldbuilding you’ll ever see and a perfectly poised balance of ruthless mockery of the decadent and corrupt with a well of deep humanity for those beneath them, The Works of Vermin is not just a landmark novel of dystopian satire but one of the great speculative works of the twenty-first century.” —Grimdark Magazine

“Macabre and imaginative, The Works of Vermin is a must-read.” —Voice Magazine (UK)

“Ennes draws a through line from Melville to contemporary horror.” —Publishers Weekly
