Readers were annoyed to discover something galling: evidence that an author used AI, right in the middle of a novel.

The novel, titled “Darkhollow Academy : Year 2,” penned by author Lena McDonald, falls under a romance subgenre called “reverse harem,” which conventionally follows a female protagonist with multiple male partners.

But as eagle-eyed fans of the genre were irritated to discover, the author left glaringly obvious evidence of not only using an AI chatbot to write portions of the book — but also of a naked attempt to copy the style of a real fellow writer.

“I’ve rewritten the passage to align more with J. Bree’s style, which features more tension, gritty undertones, and raw emotional subtext beneath the supernatural elements,” a since-deleted passage in chapter three of the novel reads, as seen in screenshots posted to the ReverseHarem subreddit earlier this month.

J. Bree is the human author of an internationally bestselling series of romance and fantasy novels.

The instance is yet another illustration of how Amazon is being flooded with self-published AI slop, a trend that has been going on ever since the tech went mainstream a few years ago. It’s a real problem for human authors, too, with AI-generated books drowning out their work in search results pages.

In one particularly egregious example, author Jane Friedman discovered back in 2023 that roughly a dozen books were being sold on Amazon with her name on them.

Understandably, the small ReverseHarem community on Reddit was outraged after McDonald was caught blatantly using AI to rip off the voice of a real author.

“I just about fell out of my chair when I read this!” wrote the user who shared the screenshots.

“I got the book to provide secondary confirmation that this is real,” another user chimed in. “Which means everyone has now read part of the book, which qualifies for a Goodreads rating, and possibly even Amazon.”

Readers tore into the book in a storm of one-star reviews.

“This was written with generative AI, as is clear by the prompt that was left in the book before uploading to Amazon,” one disgruntled reviewer wrote. “I will support authors in many, many ways, but generative AI is theft and it’s not a replacement for actual writing.”

“I would assume all of her other writing uses AI as well, as book 1 of this series released 1/24/25, book 2 on 3/13/25, and book 3 on 3/23/25,” one GoodReads reviewer wrote. “That’s faster than Steven King.”

A book reviewer account called Indie Book Spotlight put it a lot more bluntly in a Bluesky post.

“F**k you if you steal and copy authors’ works,” the user wrote. “F**k you if you use gen ai and call yourself a writer. You’re an opportunist hack using a theft machine.”

McDonald’s blunder is just the tip of the iceberg. Two other purported authors identified by Indie Book Spotlight were caught dabbling with generative AI to churn out novels.

Earlier this year, a writer who goes by KC Crowne was also seemingly caught leaving ChatGPT prompts in the text of their work.

“Thought for 13 seconds,” one passage of a book titled “Dark Obsession” on Amazon reads, as seen in screenshots posted to the RomanceBooks subreddit in January. “Certainly! Here’s an enhanced version of your passage, making Elena more relatable and injecting additional humor while providing a brief, sexy description of Grigori.”

Crowne’s Amazon page features a whopping 171 titles, each adorned with an AI-generated cover of topless, tattoo-covered men.

“International Bestselling Author and Amazon Top 8 US Bestseller,” the author’s bio reads.

A third writer, who goes by Rania Faris, was also caught using an AI chatbot.

“This is already quite strong, but it can be tightened for a sharper and more striking delivery while maintaining the intensity and sardonic edge you’re aiming for,” reads a passage one Threads user discovered in a printed copy of Faris’ book.

Oddly enough, Crowne’s novels are getting predominantly positive reviews on GoodReads, indicating they have found their niche, and readers may either not care or not be aware of the use of AI.

Users on Bluesky were sharing theories as to why.

“Oh wow, I just caught up on the KC Crowne AI thing,” award-winning Canadian author Krista Ball wrote in a post back in January. “So setting aside the AI prompt left in the book, I am amazed that this wasn’t mentioned anywhere by the early readers, the street team, etc – which leads into my paranoid theory that a percentage of readers are just skim reading.”

“Remember back in the day when writing fast was like a good reputation builder?” she added. “Now it’s sus as all hell.”

Neither McDonald nor Faris has publicly listed contact information. Crowne, at least, is taking accountability for the situation.

“Earlier this year, I made an honest mistake,” Crowne wrote in an email to Futurism. “I accidentally uploaded the wrong draft file, which included an AI prompt. That error was entirely my responsibility, and that’s why I made the tough decision to address it publicly.”

Crowne claimed that “while I occasionally use AI tools to brainstorm or get past writer’s block, every story I publish is fundamentally my own,” saying that “I only use AI-assisted tools in ways that help me improve my craft while fully complying with the terms of service of publishing platforms, to the best of my ability.”

AI or not, Crowne has somehow published 171 novels over the last seven years.

Whether the use of generative AI in self-published books on Amazon breaks any rules remains somewhat unclear. An Amazon spokesperson pointed us to the company’s content guidelines, which govern “which books can be listed for sale, regardless of how the content was created.”

The guidelines have an entire subsection dedicated to the use of AI, which stipulates that “AI-assisted content” is permitted and sellers aren’t even “required to disclose” its use. However, any “AI-generated images include cover and interior images and artwork” have to be labeled as such.

The internet at large is also facing an existential threat in the shape of an AI slop tsunami. Do we really need to extend that trend to 300-page fantasy novels to read on the subway to work?

Self-published authors who are trying to stand out in an already busy marketplace aren’t hopeful.

“They bring down the reputation of those of us who don’t touch AI to write our books,” author Catherine Arthur tweeted. “Being tarred with the ‘self-published = written by AI’ label is not good, and if they don’t stop, then that’s what may happen.”
