How Romantasy & BookTok Changed the Game for Sci-Fi & Fantasy

In the past two years, something remarkable has been happening in the book world. Science fiction and fantasy, often thought of as “niche” genres, have suddenly become some of the fastest-growing categories. Sales have soared, and much of the credit goes to two powerful forces: romantasy and the unstoppable reach of BookTok. Romantasy — a mix of romance and fantasy — has given readers stories that feel both magical and emotionally gripping. It’s not just about battles or world-building, but about love, passion, and connection set against fantastical backdrops. Readers are devouring books like Fourth Wing and its sequel, sharing quotes, fan art, and reactions online. BookTok, the book-loving corner of TikTok, is amplifying these voices, turning niche titles into global sensations. This surge has changed the balance in publishing. While fiction sales in general are up, other categories are struggling. Non-fiction, particularly celebrity memoirs, has seen a slump. Children’s books have dipped slightly too. But sci-fi and fantasy are thriving like never before. Publishers are noticing, and many are shifting focus to meet demand for romantasy titles. Why Readers Are Hooked on Romantasy • Escapism: fantasy worlds mixed with romance give readers a way to step out of daily stress. • Strong emotions: love stories make readers care deeply about characters’ fates. • Familiar tropes with magic: enemies-to-lovers, chosen ones, forbidden love — all dressed in fantastical elements. • Community effect: once a book goes viral on BookTok, everyone wants to join the conversation. Romantasy has also brought new readers to sci-fi and fantasy who might have avoided the genres before. Romance lovers are stepping into magical realms, while fantasy fans are embracing love stories as central to the adventure. This crossover has widened the audience and made these genres more mainstream. Of course, trends have their downsides. Some critics argue that the boom has led to repetition, with too many books copying the same formulas. Others worry about overlooked genres that don’t get the same social-media spotlight. Yet, it’s undeniable that this movement has sparked excitement about reading again, especially among younger audiences. In the end, romantasy and BookTok have proven that storytelling thrives where passion and community meet. They’ve not only boosted sales but reminded people why books matter: because they let us dream, escape, and feel connected — even in worlds that don’t exist. 10 Popular Romantasy Books Right Now • Fourth Wing by Rebecca Yarros • Iron Flame by Rebecca Yarros • From Blood and Ash by Jennifer L.
