Leech: Creepy, Unputdownable Gothic Horror
Purchase options and add-ons
'Unique and utterly assured, I will follow this writer anywhere' – Gillian Flynn, author of Gone Girl
‘A wonderful new entry to Gothic science fiction, impeccably clever and atmospheric. Think Wuthering Heights . . . with worms!’ – Tamsyn Muir, author of Gideon the Ninth
The Times Best Sci-Fi Books 2022 and Winner of The Sydney J. Bounds Award for Best Newcomer at the British Fantasy Awards 2023.
In an isolated chateau, as far north as north goes, the baron’s doctor has died. The Interprovincial Medical Institute sends out a replacement. But when the new physician investigates the cause of death, which appears to be suicide, there’s a mystery to solve. It seems the good doctor was hosting a parasite. Yet this should have been impossible, as the physician was already possessed – by the Institute.
The Institute is here to help humanity, to cure and to cut, to cradle and protect the species from the horrors their ancestors unleashed. For hundreds of years, it has taken root in young minds and shaped them into doctors, replacing every human practitioner of medicine. But now there’s competition. For in the baron’s icebound castle, already a pit of secrets and lies, the parasite is spreading . . .
These two enemies will make war within the battlefield of the body. Whichever wins, will humanity lose again?
Leech by Hiron Ennes is an atmospheric Gothic triumph, perfect for fans of Jeff VanderMeer and Silvia Moreno-Garcia.

Review
A wonderful new entry to Gothic science fiction, impeccably clever and atmospheric. Think Wuthering Heights . . . with worms! -- Tamsyn Muir, author of Gideon the Ninth
Leech isn’t like anything I’ve read before. Superb writing, interesting and fresh ideas, skilful execution. Highly recommended. I’ll be reading anything Hiron Ennes writes from now on -- Tade Thompson
What a unique book! Surprising turns and staggering ideas – all woven together by beautiful writing. This is one to remember -- Tim Lebbon
I didn’t know a book could perfectly convey the concept of a distributed intelligence, alive and aware of each of its proxies, but Leech is proof anything is possible in good hands -- Cassandra Khaw
If you’ve ever wondered what would happen if David Cronenberg and Edgar Allen Poe bumped into each other at the same parasitological conference, here’s your answer -- Peter Watts
Ennes spins classic Gothic horror and fascinating science fiction into a creation that is disturbing, horrifying, and impossible to turn away from -- Brom
Leech is wonderful, with a truly unique protagonist, a goeey, squicky post-apocalyptic setting, and a dose of Gormenghast gothic. Perfect for fans of Gideon the Ninth and The Traitor -- Django Wexler
A tense, disturbing work of Gothic horror that embraces difficult themes of power, abuse, agency and raw survival in an unforgettably apocalyptic setting. Gory, shocking, raw – and utterly humane -- Kameron Hurley
Part of me admires the sheer level of craft that Ennes put into this book, but another part of me feels it must surely have been unearthed, whole and eerie and throbbing, in a box in a dark attic. Gothically bloody, beautifully written, and sharp as a scalpel to the amygdala. I loved it -- Freya Marske
Hiron Ennes's debut is an intricate, well-observed marooned-community thriller -- The Times
Uniquely compelling -- Financial Times
Fans of gothic horror will find a lot to love . . . Hiron Ennes juxtaposes cosily old-fashioned gothic imagery, such as snowy fields and cavernous castles, with genuinely shocking bouts of body horror . . . It's delightfully malignant, prompting questions about who the villain really is, and making Leech feel even more ambiguous and alluring -- SFX

Brilliant stuff
Reviewed in the United Kingdom on 16 May 2025Somewhere in the icy, fog-choked region where "Gormenghast" overlaps with "The Thing" and "A Canticle for Leibowitz" sits "Leech", an imaginative blend of Gothic horror and body horror told from a unique viewpoint.
It's fairly fast-paced and an easy read, but around the edges of the plot there's a lot of interesting world-building for those who like to connect dots and come up with conjectures. A very skillfully written book, and highly recommended.

Strange but one the best books I’ve read
Reviewed in the United Kingdom on 11 November 2022leech merges many genres & it’s over all outcome is brilliant!!! Gothic, post-apocalyptic sci-fi & speculative fiction. The book is also metaphors for colonialism, capitalism & SA. With some fables thrown in.
Leech is probably one of the strangest books I’ve ever read.. but one of the best. It’s very original. Imagine you were looking at humanity through a microscope and you were able to see everything about humanity & patterns. In the beginning things appear quite ordinary (very human) but alongside the narrator this world is very unordinary.
The best way I can describe Leech is like this .. it’s like you’re having a conversation with someone and you’re not entirely sure what they’re on about but you don’t want to appear stupid so you carry & pretend. Then another person comes into the conversation & they start talking more in depth but you’re still kind of unsure because things aren’t really been explained. The prose is very mysterious like its narrator - things are revealed slowly but not explained… if that makes sense. Everything is revealed at the right time but at the same time I’ve never read a book like it. The tone of the prose has a strong 19th century writing style which i loved! It also has a little classic feel to it. The book is very confusing at times but with pseudo-omniscience it was very well written.
This is a hard review for me to write there are details which I think is best left to the reader to discover on their own. For me giving these details would ruin the experience.. annoyingly quite a few reviewers have done this & not given a spoiler warning.
My only issue with leech was thus, There is SA scene which in my opinion was unnecessary & came out of no where. There was already violation to one of the characters which I think was a metaphor for this anyway & towards the end things did kind of spiral. Also I should add none of the characters are extremely likeable.

Ok but not blow your socks off
Reviewed in the United Kingdom on 4 April 2024This book started out very well with an interesting plot that I was pretty excited to get into but quickly lost its way the major event happened in the middle then very quickly lost pace and I found myself only reading on to see if it got better. Bit of a disappointing ending with way top much trying to happen in a short space of time. Maybe with another read it would be better but for me I wouldn’t read it again

They’re right, it’s “unputdownable”
Reviewed in the United Kingdom on 11 August 2024I picked up Leech ages ago out of mild curiosity and left it to linger in my to-be-read pile. I started reading it because I couldn’t decide on anything else to read.
And I couldn’t stop reading it.
It’s a horrifying premise of parasites and secrets. And it’s a pleasure to read a book by a writer who doesn’t spoonfeed you. In fact, I wouldn’t be surprised if I’ve missed a few things or two as I frantically turned pages to find out what happens next. This is a book that will reward a reread.
It’s creepy. It’s sad. It’s horrifying. It’s moving. It definitely doesn’t deserve to wait around for you in a to-be-read pile.

Gothic horror with a sci-fi twist
Reviewed in the United Kingdom on 26 October 2023In an isolated town, the Baron’s Doctor is found dead. The Medical Institute , that is the only supplier of medical personnel, sends a new doctor, he finds the old one was infected with a parasite. That is impossible as all Doctors are already possessed.
This is difficult to explain, the main character is a body possessed by an intelligent symbiotic life form that is in countless other bodies and whose mind sees through the eyes of all of them, like a hive mind. Then along comes competition, an invasive parasite that lives inside humans. Unlike the Institute who has for hundreds of years replaced all doctors and chooses the brightest minds, the new threat is not so choosy.
This is gothic horror with an almost sci-fi twist, the language is archaic and very much of the gothic period and this can take some getting used to but the writing is beautiful and evocative. There is tension throughout the story but it is weirdly compelling. The creeping invasive parasites, the cold, harsh, unforgiving land, the heartless hardened people, the atmosphere feels heavy and malignant. A fascinating read.

Creepy!
Reviewed in the United Kingdom on 17 October 2022The title & cover were enough to capture my interest without even reading the blurb. It still begs the question - what on earth have I just read? Gothic, creepy & weird - I couldn’t read it in one hit; I had to process it gradually.
The baron’s doctor dies at an isolated chateau. His eerie replacement arrives & discovers something in the mines deep below the chateau.
I don’t generally read horror & although this is not strictly in that genre, oh my, I did recoil in places. Unique in storyline, a quirky writing style (which may put some readers off) & definitely different.

Disappointingly dull
Reviewed in the United Kingdom on 28 December 2025I usually love horror but this was dull and monotonous. Plodded along.

Christine Huff5 out of 5 starsNever read Anything like this before!
Reviewed in the United States on 8 May 2023I love to find a book that tells a story I’ve not heard before. “Leech” is just such a book with an amazing story. I traveled down passages I’ve never even considered. It is a difficult read in the beginning, but the story gradually reveals itself to the reader and finishing it is well worth the effort.
The author regularly challenged my vocabulary and I had it use the kindle dictionary. But it wasn’t done in an obnoxious way. The words chosen fit with the dystopian ageless feel the book created. At once, I felt as if I were in Victorian England and in the our earth’s bleak future. This feeling started on the first page and permeated throughout the book.
What also impressed me is the description of sexual violence. The writing was elegant, not graphic, which actually made the horror of it all the more terrifying.
I found it to be an amazing novel, and was stunned to discover this is the authors first book. I look forward to reading everything this author writes.

Robert Young2 out of 5 starsQuite verbose
Reviewed in Canada on 22 May 2026I felt like this would have been an excellent short story, and really painful as a full novel. I see a lot of people enjoy it, perhaps my read was off but I would not recommend.

Seraph4 out of 5 starsEntertaining and imaginative novel.
Reviewed in Germany on 8 March 2024I bought this novel to read it during a business trip while on a train. Surpassed my - admittedly low - expectations. I mean, the book was labelled "unputdownable" (!) by marketing. But it actually proved to be to me. I continued with it way after I was back home from my two day trip. I think it captures what you could call a Lovecraftian atmosphere, not because it has some of the Great Old Ones in it, but in the way the whole world appears hostile to its inhabitants with horrors beyond the imagination of its human inhabitants. I never witnessed a similarly unique main character - the world building and the power of imagination that went into building this world and the characters is fantastic. I could almost feel the icy cold winter. I also liked the writing style - definitely better than Lovecraft, which does not mean much because he was a pretty bad writer in my opinion - despite having great world building capabilities. Only thing I disliked was the massive use of flashbacks to draw on the background of the main characters. I would probably have voted 5 stars without that.

kelliea4 out of 5 starsWhose thoughts are you thinking?
Reviewed in Australia on 13 March 2023A disturbing examination of what makes a person, memories, experiences or the physicality of a body- all these things or the stories of existence living outside of and all around life forms.
