I just recently watched The Substance, that crazy body horror movie starring Demi Moore, and my brain still hasn’t fully recovered. It’s the kind of dark satire that relishes making you uncomfortable while shining a twisted light on our deepest societal insecurities, especially with regards to vanity and self-destruction. With Feeders by Matt Serafini: same vibes, but different angle. While the book doesn’t do sci-fi or transformational horror, it does boast its fair share of gore and follows a protagonist so desperate for validation and celebrity that she’s willing to debase herself and hurt others to get it.

The story follows nineteen-year-old Kylie Bennington, a community college student using school as a stepping-stone toward something bigger—but what she really wants is to become an online influencer. Perpetually envious of her best friend Erin who has millions of followers on social media and gets comped gifts from sponsors, Kylie is hungry for the same attention and desperate to be someone, yet that dream always seems to feel just out of reach. That is until MonoLife comes into the picture. When a clip of a former classmate’s brutal murder begins circulating online, Kylie is made aware of the underground video sharing app, which features layers of cryptic rules and user levels. Signing up is easy, but keeping your account is another story. The first rule of MonoLife is you don’t talk about MonoLife, or you will face dire consequences. The app also requires at least two daily logins or else it will delete itself, resulting in loss of access forever.

Her curiosity piqued, Kylie is quickly drawn into MonoLife’s unique but warped culture, one driven by a userbase that thrives on edgy content that pushes boundaries. Her ambition also gradually turns to obsession as she becomes addicted to unlocking the app’s special levels, which are earned by gaining more followers and clout. In time, what started as a few harmless prank videos begin escalating to more extreme stunts and vile acts. Yet her audience is insatiable—and the more depraved the content she posts, the more the algorithm rewards her with fame and material wealth. Thus, by the time the story reaches its final act, Kylie has flung herself across just about every ethical line there is.

First, let’s talk about the characters. These are all awful people, which is fine because you are definitely meant to despise and occasionally even pity them. These aren’t just morally gray personalities; some are darker than the pits of hell. Kylie, for one, is equal parts horrifying and fascinating—a vain, self-absorbed, and unstable powder keg willing to go to any length for subscribers and likes. While I had to keep reminding myself that her over-the-top characterization is by design, there’s also something disturbingly real about her zeal, considering the numerous studies showing that a large percentage of Gen Zers list social media influencer as their dream job. For what it’s worth though, Serafini even doesn’t try to redeem his protagonist, and I respect that. It makes you question if Kylie was ever a good person, or if her thirst for fame was always just lurking beneath the surface—probably the case, given her obsession with influencer culture and the way she worships her hero Katy Perry like a religion.

As for the horror, all I can say is, it works, even as several styles are vying for dominance here. On the one hand, you have bloody violence aplenty, enough to satisfy genre lovers whose tastes might run towards slasher flicks. On the other, there’s the existential dread, the why behind Kylie’s downward spiral into depravity and corruption. MonoLife doesn’t just encourage evil. It rewards it by triggering those surges of dopamine, leading to a need for increasingly higher doses for more intense engagement. Feeders is a brutal metaphor for the worst parts of social media, and watching Kylie succumb to it is a lot like watching a car crash in slow motion—you simply can’t look away.

My final verdict: Feeders is a dark and disturbing novel steeped in social commentary, one that feels especially relevant in these hyper plugged-in times. Bear in mind it’s also a satire that’s completely over-the-top and not at all shy about making you squirm. So, if you’re into bold topical horror that holds absolutely nothing back, this book might be for you. Who it’s not for are the squeamish, or for readers looking for happy endings and sympathetic characters to root for. Still, it leaves an impression, and maybe even a few lingering thoughts to chew on.
