Many romantasy books coming out in 2025, it's difficult to predict which ones will be viewed the most favorably come December.
In just the last month, there's been much discussion surrounding several books. The debate over whether controversy surrounding Dani Francis' book stemmed from its popularity on the platform. And with both of those titles in the rearview mirror, there's another romantasy sensation sweeping social media: The Knight and the Moth by Rachel Gillig. The buzz surrounding this book is definitely warranted, and it could even be one of the year's best romantasy offerings.
The Knight And The Moth Is BookTok's Latest Obsession & Totally Worth The Hype
It Has Everything You Could Want From A Romantasy Book (Including A Hilarious Gargoyle)
On the heels of Silver Elite and Shield of Sparrows at the beginning of May, The Knight and the Moth is emerging as the internet's latest romantasy obsession — and it's not hard to see why. From the author of The Shepherd King books, The Knight and the Moth kicks off a new duology dubbed The Stonewater Kingdom. With a gothic backdrop in line with Gillig's prior series, the 2025 novel follows a woman named Sybil Delling, who has spent most of her life working as a Diviner for Aisling Cathedral.

It's easy to understand why Fourth Wing has become such a huge phenomenon, but there are a number of romantasy books that are just as good.
Sybil doesn't know who she is outside of her role, which involves repeatedly drowning and giving prophecies to those who visit Aisling. She and her sisters are eager to start their lives anew once their 10-year tenure at the cathedral is up. However, right after the new king and his knights visit, Sybil's fellow Diviners begin disappearing one by one. This sends her on a journey to find them, forcing her and her reliable gargoyle (who hilariously calls everyone "Bartholomew") to team up with the young king and his knights.
The premise of The Knight and the Moth meshes gothic fantasy, romance, and mystery to brilliant effect.
The premise of The Knight and the Moth meshes gothic fantasy, romance, and mystery to brilliant effect, easily immersing readers in Gillig's new fantasy world. Sybil is a likable and sympathetic heroine, and her sisterhood with the other Diviners makes it impossible to avoid becoming invested in her journey. The bat-like gargoyle who follows and protects her is a highlight of the novel, injecting humor into an otherwise thoughtful exploration of faith and power. And of course, the romance between Sybil and the heretical knight she falls for delivers on the tension.
