In 2018, a romantasy submission, romance with a fantasy spine, usually featuring fae, dragons, or a court of some kind, was a hard sell at most of the major imprints. Buyers were polite but uninterested. The category did not exist as a category. By 2024, those same imprints were paying seven-figure advances for debut series in exactly that shape, and the trade press was openly admitting that nobody on the acquisitions side had seen it coming.
They had seen it coming. They had just decided it did not count. The readers were always there. The infrastructure that connected the readers to each other was not.
A short timeline
- 012014. Self-published romantasy quietly becomes one of the highest-earning categories on Kindle Direct Publishing. Trade publishing does not notice.
- 022019. A handful of indie authors cross half a million ebook sales without trade distribution. Trade publishing notices but assumes the ceiling is low.
- 032022. A debut romantasy from a small imprint goes viral on TikTok and spends most of the year on the New York Times list. The ceiling turns out to be very high.
- 042024. Romantasy is the single most-bought physical-book category for readers under thirty-five, by margin.
Why the genre, specifically
There is a useful way to read the boom that has nothing to do with dragons. Romantasy books are, on average, long. Often 600 pages, sometimes 900. They are sold in series, which means a reader who finishes book one can immediately enter book two with the same characters, the same world, and no onboarding cost. The experience is closer to a long-running prestige television show than to a standalone novel.
For a reader looking to spend three weeks of evenings inside a single fictional space, this is the optimal product. The romance plot guarantees emotional payoff. The fantasy scaffolding guarantees scale. The series structure guarantees that the experience does not end at chapter forty.
“The boom was never about dragons. It was about long books that ask nothing of you except presence.”
The attention economics
A short-form-video user, on average, watches roughly 90 minutes of clips per day. That is 90 minutes of context-switching, novelty, and cognitive friction. Romantasy is the inverse product: many hours of single-context, low-friction immersion. The two coexist in the same reader, often the same evening, because they do different things.
It is tempting to frame the boom as a rebellion against the phone. It is more accurate to frame it as a complement. The phone fragments. The book reconsolidates. Readers who have spent the day in the first mode use the book to recover.
What the genre is actually optimizing for
Trade publishing has historically optimized for prestige, prize lists, and critical reception. Romantasy optimizes for reread value. Most of the highest-selling titles in the category are not bought because the reader expects them to be the best book of the year. They are bought because the reader expects to reread them, sometimes three or four times, in the years after.
Reread value is the metric the boom turned on. It is also the metric the industry was not measuring.
