From AO3 to Bookstores and Screens: How Fanfiction Becomes Original Fiction

Every so often, a familiar kind of story resurfaces: a bestselling novel turns out to have started as fanfiction, or a screen adaptation can be traced back to AO3 or another fan platform.

It is easy to turn that into a fantasy of its own. Someone writes fanfic online, readers recommend it everywhere, a publisher arrives, the names change, the cover changes, the book lands in stores, and then film people come knocking. It sounds like a secret corridor from the comment section to the red carpet.

Reality is less smooth than that. Still, these cases show that fanfiction is not just “writing for fun” in the dismissive sense. Some fanworks leave behind strong narrative structures, relationship dynamics, and reader memories. Later, an author may take those pieces apart, rewrite them, rename them, and turn them into original fiction that can enter commercial publishing.

This is not a guide to finding deleted fanfics, and it will not collect links to pulled works. The more interesting question is: what actually changes when a fanfic moves toward publishing or screen adaptation?

It is not selling an AO3 work as-is

AO3’s Content Policy is clear about its purpose: AO3 hosts transformative, non-commercial works created by fans around the world. It is a non-commercial archive for fanworks, not a commercial publishing platform.¹

So when people say “this novel started as fanfiction,” that does not mean the author simply took an AO3 work and sold it unchanged. More often, the original fanwork is heavily rewritten. Protected elements are removed: character names, setting names, world-specific rules, and anything that depends too directly on the source IP. The goal is to make the story stand as its own original work.

In English-language fan and publishing discussions, this is often called filing off the serial numbers. The phrase is useful because it captures the first step: removing the parts that make the original source instantly recognizable. But that is only the beginning.

It is not just a find-and-replace job. A publishable version usually needs new worldbuilding, new character backgrounds, new motivations, and sometimes whole side plots removed or rebuilt. Readers may still sense familiar tropes, such as enemies to lovers, fake dating, or forced proximity, but the story can no longer rely on the source canon to explain itself. What remains is often a relationship model, a rhythm, and a kind of familiar tension, not the original character identities.

Case one: The Love Hypothesis and Reylo

The Love Hypothesis is one of the most frequently discussed examples.

Marie Claire’s 2026 coverage of the film adaptation notes that Ali Hazelwood’s STEM romance was first posted on AO3 as a Rey Skywalker / Kylo Ren, or Reylo, alternate-universe fanfiction. The original fic has since been taken down. The same article notes that the book was published in 2021, became a bestseller, and is now being adapted for the screen.²

This is a classic example of a fanfic relationship model moving into original romance. What is carried over is not Rey and Kylo’s literal identities, but the way two characters pull against and toward each other.

Reylo lends itself easily to modern AUs: strong contrast, tension, and the feeling that two people probably should not get close but do anyway. In The Love Hypothesis, that structure is moved into an academic romance: a PhD student, a professor, fake dating, labs, and professional pressure. You do not need to have watched Star Wars to read it, because the published story no longer depends on those original identities.

For some readers, learning about its Reylo background adds another layer of interest. Not because the book is secretly still writing Star Wars, but because it shows how a dynamic developed in fanfiction can be repackaged for mainstream romance.

The Love Hypothesis was not the first fanfiction-to-publishing case. But it helped many readers notice that the narrative experience developed on AO3 can leave its original fandom and enter a much larger publishing market.

Case two: Manacled to Alchemised

If The Love Hypothesis is a lighter romance case, Manacled / Alchemised belongs to a different category.

In a 2025 interview with novelist SenLinYu, The Guardian notes that the author had written Harry Potter fanfiction, with Manacled as their best-known work. That fic centered on Draco / Hermione, also known as Dramione, and drew a large readership during the pandemic. SenLinYu later rewrote the story, removed Harry Potter and other third-party IP elements, and published it traditionally as the original novel Alchemised. The Guardian also reported that Alchemised had already secured a seven-figure screen rights deal.³

This case makes one thing very clear: rewriting is not a light reskin. In the same Guardian piece, SenLinYu says they began rewriting Manacled around Christmas 2022. The article also notes that the rewrite had to strip out obvious references to Harry Potter and The Handmaid’s Tale, while building a new world and magic system. Publishing the book was not just a matter of changing Hermione and Draco into new names. The whole world had to stop depending on the original sources.

For readers who knew the fanfic, that shift can feel complicated. On one hand, many people are excited to see an author get publishing and screen opportunities. On the other, the original work being taken down, rewritten, and moved into a commercial system changes a shared memory.

Before, it was a fic that could be commented on, screenshotted, recommended, and discussed inside fandom. Later, it became a book, a rights deal, and a media topic. It still carries shadows of its earlier life, but it now operates under a different set of rules.

A boundary case: Heated Rivalry

Heated Rivalry, the hockey romance series that has recently drawn a lot of attention, needs a more careful explanation. It does have an AO3 connection, but it is not simply “an AO3 fic directly adapted for television.”

The show is based on Rachel Reid’s Game Changers series, and its central pairing is Shane Hollander / Ilya Rozanov. The AO3 connection is most direct with Game Changer, the first book in that series. In other words, AO3 is part of the early circulation history around the series, not the direct source text of the show.

Them’s coverage of this history says that after first writing Game Changer, Rachel Reid rewrote it as an alternate-universe fanfic featuring Steve Rogers / Bucky Barnes, or Stucky, and posted it to AO3. Later, the story returned to an original publishing path and became the starting point of the Game Changers series.⁴

That makes this case interesting because it is not the standard route of “fanfic first, original novel later.” According to public reporting, it is more of a detour: Reid first wrote an original story, then rewrote it as Stucky fanfiction because she thought AO3 only allowed fanfiction, then removed the Marvel elements and returned it to original fiction. So yes, the Game Changers series had an early AO3 stage. But the TV version of Heated Rivalry is not a direct adaptation of an AO3 fanfic. It is a useful example because original fiction, fanfiction, and publishing do not always move in a straight line.

Earlier examples: not every road starts on AO3

Looking further back, two examples often appear in fanfic-to-publishing discussions: Fifty Shades of Grey and After. They do not really belong to the current AO3 era, but they show that fanfiction entering commercial publishing is not a new phenomenon.

Fifty Shades of Grey began as the Twilight fanfic Master of the Universe. It was first serialized on fanfiction sites, then rewritten as original fiction. The characters corresponding to Edward and Bella became Christian Grey and Anastasia Steele, and the books later became a film series.⁵

After took a different path. It was first serialized on Wattpad and had a direct connection to One Direction / Harry Styles RPF culture. When it moved into publishing, the characters were rewritten as Tessa Young and Hardin Scott, and the story later became a film series.⁶

These two cases predate The Love Hypothesis and Alchemised, and they do not belong to what many people now think of as the “AO3 era.” They are useful as background: fanworks entering commercial publishing did not begin with AO3. AO3’s tags, longfic culture, and reader communities have simply made these paths easier to trace and discuss.

Red, White & Royal Blue should be handled more cautiously. It has a strong fandom and queer romance sensibility, and it has been adapted into a film. But public background materials more commonly describe Casey McQuiston as developing the story from the 2016 U.S. election, Veep, Hillary Clinton biographies, and The Royal We.⁷ It is better understood as original romance shaped by fandom-adjacent sensibilities, rather than as a direct fanfiction-to-publishing example.

Why do original fanfics often get deleted or pulled?

This is usually the question readers care about most: why does the original fic often become impossible to find after publication?

The first reason is the copyright boundary. A published version needs to enter the commercial system as original work. It cannot continue to depend on source characters, settings, or protected elements. If the original fanfic remains publicly available, readers can compare the two versions paragraph by paragraph: what was only renamed, what was rewritten, and what still looks tied to the source. That creates more explanation work for both author and publisher.

The second reason is marketing and positioning. The published novel needs to be introduced, sold, and adapted as an independent work. It can have a fanfiction background, but readers should not feel they need to know the original fandom in order to understand it.

The third reason is author control. Once a fanfic becomes extremely popular online, downloads, reposts, pirated copies, unauthorized translations, and cross-platform reuploads can spread quickly. Pulling the work can be one way for the author to regain some control over how the story circulates. This is different from AO3’s orphaned works: orphaning keeps a work in the archive but separates it from the account. Pulling a work before publication often means moving the story into another stage of its life.

So it is too simple to read a pulled fic as an author “betraying fandom.” More accurately, the work has changed systems. It no longer faces only fandom readers. It also faces publishers, screen rights, contracts, bookstore categories, and a much wider public conversation.

What role does AO3 play here?

AO3 is not a publishing platform, and it does not send fanfics to publishers on behalf of authors.

It is closer to a place where fanworks can be written, read, commented on, and preserved. Many authors use AO3 to practice pacing, relationship dynamics, long-form serialization, reader interaction, and trope handling. If a work happens to be remembered by many readers, that experience may later become part of the author’s original writing life.

AO3’s Terms of Service FAQ also says users may post their own content elsewhere, or remove it from AO3 if they no longer want it hosted there. AO3 does not charge readers for access to user content, and it does not sell user content.⁸

That matters. AO3 provides a non-commercial archive space for fanworks, but it does not own an author’s creative future. An author can write fanfiction on AO3 and later write original fiction. They can keep old works, delete them, post anonymously, orphan them, or take the core of a story and rewrite it into something completely different.

From that angle, calling AO3 a “training room” for commercial writers feels too utilitarian. It is more like a loose creative space. Some people play there for a while. Some stay for years. Some eventually take what they learned and go elsewhere.

How should readers approach these works?

If you enjoy the published version, you do not have to prove that you “spotted the original.” If you know its fanfiction background, you do not have to treat that background as a scandal either. Many stories gain power through retelling: myths are retold, classics are rewritten, superheroes are rebooted. Fanfiction does something similar, often in a more intimate and community-based space.

At the same time, it is worth respecting how authors handle the original fanfic. If the original work has been taken down, do not go hunting for pirated PDFs. If the author has not authorized translation, do not assume “it used to be free” means you can translate and repost it. Once the published work has become original fiction, it should not be treated as a full replacement for the original fandom either.

These works once were fanfiction, so readers can see fandom habits, relationship tension, and trope traditions inside them. Later, they became original novels, which means they have to carry their own worldbuilding, characters, and copyright responsibilities.

The path from AO3 to bookstores and screens sounds glamorous. But what usually happens along the way is a lot of rewriting, deleting, cutting, and renaming. What remains is not only “the shadow of the original ship.” It is also the narrative instinct an author developed in fandom.

Fanfiction can be private, small-scale, and informal. Sometimes, though, it travels much farther, and readers who never knew the original fandom can still be drawn in by the same kind of story tension.
