If 2023 was the year romantasy went mainstream and 2024 cemented it, 2025 was the year it took over. Fantasy romance dominated bestseller lists, broke sales records, and pulled in readers who'd never picked up a dragon book in their lives. The genre stretched in every direction this year — from record-shattering dragon-rider sequels to gothic debuts that started life as fanfiction, from dystopian crossovers to quiet, lyrical standalones. Here are the romantasy books that defined 2025, with heat levels, core tropes, and an honest sense of what each one actually is.
Onyx Storm by Rebecca Yarros
The biggest romantasy release of the year, full stop. The third Empyrean book sold 2.7 million copies in its first week — the best opening for any adult novel in two decades. Picking up after the cliffhanger of Iron Flame, Violet Sorrengail must journey beyond the failing wards of Aretia to unfamiliar lands, searching for allies and answers while the threat closing in on Navarre grows by the day. It's the connective-tissue middle of a planned five-book arc, and reviews were more divided than the sales suggest — but if you're invested in Violet, Xaden, and the dragons, this is non-negotiable reading. New to the series? Start with Fourth Wing.
Alchemised by SenLinYu
The debut phenomenon of 2025. SenLinYu's novel hit #1 on the New York Times list the week after release and stayed on the chart for fifteen straight weeks, with film rights selling for a reported seven figures. In a world ruled by necromancers, former alchemist Helena Marino wakes a prisoner with no memory of the months before her capture — and her captors suspect those missing memories hide the secret that could undo them. Worth knowing going in: although it's often shelved as dark romance, Alchemised is more accurately dark, gothic fantasy with a central love story, and it carries heavy content warnings. A reworking of the author's wildly popular fanfiction, polished into something entirely its own.
The Knight and the Moth by Rachel Gillig
From the author of One Dark Window comes a #1 bestselling gothic romantasy with a devoted following. Sybil Delling — known as "Six" — is a Diviner who ritually drowns to receive omens from the gods. When her sister Diviners begin vanishing one by one, she leaves the only home she's known and sets out with Rory, a rude, heretical knight whose future is the one thing she cannot see. Atmospheric and mist-soaked, with a scene-stealing gargoyle sidekick readers fell in love with, it's the gothic-fairytale end of the genre done with real craft.
Rose in Chains by Julie Soto
One of the buzziest — and most debated — debuts of the year, and a #1 Sunday Times bestseller. The war is over, the dark forces have won, and Princess Briony Rosewood is stripped of her magic and auctioned off to the enemy: Toven Hearst, a morally grey scion of the rival kingdom and her own unresolved infatuation. Built on a magic system that pits "heart magic" against "mind magic," it's a dark, slow-burn romantasy with dual timelines and serious content warnings. Like several books on this list, it began as fanfiction before being reworked for publication.
Silver Elite by Dani Francis
2025's big dystopian-romantasy crossover, pitched to readers who grew up on The Hunger Games and Divergent. Wren Darlington is a "Mod" — psychically gifted in a world where being Modified means death — who's hiding the full extent of her power. When a single mistake lands her in enemy hands, she's forced into their most elite military training program, and into a forbidden slow-burn with exactly the wrong person. The dystopian worldbuilding is lighter than the comparisons suggest, but the recruit-and-officer tension and propulsive pacing made it a runaway BookTok hit.
Dire Bound by Sable Sorensen
One of the year's standout enemies-to-lovers fantasy romances and a Sunday Times bestseller. Dire Bound opens the Wolves of Ruin series with the dark, high-angst, fated-bond energy that's powered so much of the genre's recent success — morally grey leads, a slow-burn built on antagonism, and a brutal, wolfish world. If the enemies-to-lovers-with-a-bond formula is your catnip, this debut series-opener was one of 2025's most talked-about new entries in that lane.
A Forbidden Alchemy by Stacey McEwan
From the NYT-bestselling author of the Glacian Trilogy, a slow-burn romantasy with a Peaky-Blinders-inspired industrial setting and a sharp eye for class and exploitation. Nina Harrow and Patrick Colson are twelve when they're taken from their mining towns to dazzling Belavere City to test for magical potential — and discover a buried truth: Artisans aren't born, they're chosen. Years later, a Craftsman revolution throws them onto opposing sides of a war, and a mission forces them back together. Praised for grounding its romance in real stakes about power and who gets to decide whose life is worth saving.
Arcana Academy by Elise Kova
From Elise Kova, a prolific and well-established fantasy-romance author, comes an academy romantasy built around a tarot-inspired magic system. The magic-school setting remains one of the most reliably beloved corners of the genre — found family, rival classmates, forbidden attraction, high-stakes training — and Kova's experienced hand makes this a comfortable, immersive pick for readers who want the academy flavour with polish. A strong choice if Fourth Wing left you wanting more school-set magic.
When the Tides Held the Moon by Venessa Vida Kelley
One of 2025's most distinctive romantasy releases — a lush, historically-tinged fantasy with a sapphic love story at its center. Blending historical atmosphere with a magical, sea-touched premise, it stands apart from the dragon-and-academy crowd with a quieter, more lyrical register and a forbidden, slow-burn romance. A lovely pick for readers looking for LGBTQ+ representation and something that trades high-octane action for mood, longing, and beautiful prose.
Wild Reverence by Rebecca Ross
Rebecca Ross, beloved for Divine Rivals and a reliable name in character-driven fantasy romance, brings her signature warmth to a coming-of-age romantasy. Ross writes the tender, emotionally-grounded end of the genre — slow-burn romance, lyrical worldbuilding, and protagonists you grow up alongside — and Wild Reverence rounds out the year's best with exactly that. A gentler counterpoint to the darker titles on this list, and a strong pick for readers who love feeling rather than spice.
How to Pick Where to Start
If you want the cultural touchstone everyone's talking about, start with Onyx Storm (after the earlier Empyrean books) or Alchemised. For gothic atmosphere and slow-burn craft, The Knight and the Moth is the standout. If you gravitate toward the darker end — captivity, morally grey leads, heavy themes — Rose in Chains and Alchemised are the year's defining dark romantasy, but check content warnings first. And if you prefer your fantasy romance on the sweeter, more lyrical side, When the Tides Held the Moon and Wild Reverence are the gentle, character-driven picks.
The throughline across all of them is what made romantasy the genre of the moment: a real love story with real stakes, set in a world big enough to get lost in. 2025 delivered that at every heat level and in every flavour — which is exactly why it was the genre's biggest year yet.
