Must-Read Extreme Horror Books to Push Even Hardcore Horror Fans Over the Edge

Jack Ketchum is one of the all-time horror greats. His writing has this way about burrowing under your skin, bubbling your emotions, until you’re second-guessing the civilized world. Often cited as among the most horrific novels in the genre, The Girl Next Door is also based on a true story. 

In the 1960s, Sylvia Likens was captured and restrained in the suburban basement of Gertrude Baniszewski, where both Baniszewski and children from around the neighborhood tortured and eventually murdered Likens. Ketchum uses this deplorable act as the basis of the novel. Readers are introduced to David, a man living in the shadows of the events, unable to live without the knowledge of a dark criminal past. It doesn’t take long for David to recount those lazy summer days, when school was out, and he met Meg. At first all is fine and hanging out until, well, things start to go wrong. 

Ketchum deftly points the lens on the details of the true crime, refusing to hold back or look away, to utilize what extreme horror does best: It forces the reader to understand the horror like a detective, forced to look and inspect instead of looking away. There’s no better example, and no better “gateway” into the world of extreme horror than this book. Other books may pale in comparison. 

Like Ketchum, Edward Lee has carved out his own unique slice of horror, specializing in the extreme. You can’t really go wrong choosing any of Lee’s novels, yet for the sake of this list, let’s go with The Bighead. In The Bighead, we see the graphic and violent depictions indicative of extreme horror as Lee opens the door of the depraved and disturbed mind of a psychopath; the name “Bighead” comes from the fact that the psychopath has hydrocephaly, causing his head to be oversized and misshapen. 

When Bighead’s world and routine crash down after the death of his grandfather, he ventures into “The World Outside,” roaming through the woods, leaving his own sort of legacy. Reading this profane tome is like being two steps behind the path of violence, inspecting the decimation left behind.  

Kristopher Triana’s Gone to See the River Man (and its follow-up Along the River of Flesh) is a pristine example of where extreme horror can go that isn’t just violence and gore. In this breakneck short novel, Triana introduces readers to Lori, a serial killer groupie that has become obsessed with incarcerated serial killer Edmund Cox. They exchange letters, allowing Cox to coerce and manipulate Lori, eventually commanding her to go seek out “The River Man” in the woods to fully prove to him her undivided love. What follows is as much a shocking vision of violence as it is a vertical slice of a broken mind. 

The psychology surrounding the emotionally defunct Lori is palpable, and as readers continue into those ominous shadowy woods alongside Lori and her sister, Triana deftly creates this sense of dread almost too much to bear. And then the violence, the gore, and all that gritty stuff gets sprinkled in. Yet it’s what we see in Lori, the extent at which she’s willing to go for someone so evidently using and abusing her that demonstrates how extreme horror can often be excellent case studies for studying the mind of a killer and the mind of a victim. 

Here we go… if you’ve heard of this one, you’ve probably already seen how infamous this rare text really is. Written and published in the 90s on Henry Rollins’ indie label, 2.13.61, The Consumer is a collection of oddities and sheer unsettling intensity by Michael Gira, widely known for his experimental band, Swans. Though you won’t be able to find this book in print, unless you’re willing to pay those rare book prices (though there’s apparently a PDF floating around), it’s worth mentioning the book as an example of how the violence and unsettling acts that often lace the surface level of extreme horror can be bent and morphed according to the author’s intentions; in this case, Gira uses transgressions as imagery, as the basic material of every story and vignette in the collection. 

You’ll get all kinds of horror here, from self-mutilation to cannibalism and beyond, yet what Gira does with this collection is perhaps what Jerzy Kosinski had intended upon with his novel-in-stories, Steps: Create a found object of a text that transfers the inner depths of fetish and urge, humanity at its basest, as a means of making sense of it. It’s extreme and it’s odd and it’s asking of the reader whatever they’re willing to give. In turn, The Consumer willingly consumes you. 

This one is…not for the faint of heart. Let's just say that right up from. This is a list of extreme horror, after all.

Nick Graves is not a happy man. Dissatisfied with his marriage—and after making the impulsive decision to buy a dream home without consulting his wife Eve—he is blindsided when she announces her pregnancy just as he plans to ask for a divorce.

As they settle into their new home, Nick becomes increasingly uneasy with the eccentricities of their new town and Eve's strange behavior after a visit to the local doctor's office. His fear mounts as he discovers the unsettling truth about their situation, forever altering his perception of Eve. But you know what they say about “just desserts”…

Maybe or maybe not an odd choice for this list but, if you take a second and look at what this cursed text aims to achieve, it’s not too far off from what extreme horror often attains. The Marquis de Sade’s controversial and hedonistic life is documented and often discussed in the same breath as any of his books, and with good reason: He founded the principles of sadism. Yet in the book that he wrote while imprisoned, a book that remains unfinished, he took sadism to its own limits. 

The 120 Days of Sodom depicts four wealthy men who seek the peak (or one might say rock bottom) of depravity through various sexual acts and violence. They gather victims and lock themselves away in a mansion to enjoy all kinds of horrible acts. If there’s anything to glean from their behavior, all that depravity, it’s left on the page for those daring enough to read. 

I call it a cursed text not in passing either; The 120 Days of Sodom was adapted to film by Pier Paolo Pasolini, who was later abducted and murdered. Not to say it was because of the film, or because of the source material, yet when you see what ended up on the page, and what Sade had been promoting and also decrying, one can’t help but wonder if it’s true what they say, that some books are dangerous. 

Beth and Fran lead a grim existence along the devastated New England coast, scavenging the organs of feral men to avoid meeting a similar fate.

Robbie, guided by a distrustful philosophy that others pose a threat, lives by the barrel of his gun. When a tragic accident intertwines their lives, they form an unconventional family of survivors facing challenges including violent TERFs, a wealthy sociopath, and complicated interpersonal dynamics.

Amidst evading both feral men and their own inner struggles, they must navigate a treacherous landscape together.
