If your BookTok algorithm has been feeding you dark academia aesthetics and morally ambiguous love interests, Once Upon a Broken Heart by Stephanie Garber is the book your feed has been building toward. Evangeline Fox makes a bargain with the Prince of Hearts — three kisses, given whenever and wherever he chooses — just to stop the boy she loves from marrying her stepsister. It's the kind of premise that sounds deliciously reckless, and Garber leans fully into that energy. The atmosphere here is genuinely intoxicating, all velvet darkness and fairy-tale dread, with a plot that keeps pivoting when you think you've figured it out. Honest caveat: the world-building borrows heavily from Garber's *Caraval* trilogy, and if you're new to that universe, some of the lore can feel under-explained. The prose also runs purple on occasion — if you prefer spare writing, this might test your patience. But for readers who want to be *swept*, this absolutely delivers.

The Book of Azrael by Amber V. Nicole is one of those BookTok success stories that genuinely earns the hype. Dianna is a shapeshifter who sold her old life a thousand years ago to save her dying sister — and has been doing a monster's dirty work ever since. Samkiel, known to the present world simply as Liam, is a god-king so powerful he earned the name World Ender, who walked away from his throne after the Gods War and never looked back — until someone attacks the people he loves. These two are enemies in the oldest possible sense, and Nicole builds their collision slowly, painfully, and with real romantic tension before anything softens between them. The Deluxe Special Edition adds stenciled edges, character art, full-color endpapers, and a bonus scene, making it a beautiful physical object for both newcomers and fans who want to upgrade their shelf. Fair warning: this is a chunky, slow-burn epic — readers who want quick romantic payoff may find the pacing frustrating. But if you can commit to the long game, the worldbuilding and the central enemies-to-lovers dynamic are genuinely worth the investment.

Part love letter to books, part Dublin mystery, part 1920s literary time-travel — The Lost Bookshop by Evie Woods is the novel for everyone who's ever felt like a bookshop was a place slightly outside of ordinary time. The story moves between 1921 London and Paris, where Opaline flees an arranged marriage and finds her way to Shakespeare and Company, and contemporary Dublin, where Martha and Henry separately stumble onto the ghost of a vanished bookshop and a possibly undiscovered Emily Brontë manuscript. What makes it work is how genuinely charming the puzzle is — three narrators, two timelines, one mystery, and a thread of magical realism that never overwhelms the warmth underneath. It topped the Wall Street Journal's bestseller list and surpassed a million copies sold for good reason: this is comfort reading with actual literary bones. That said, the romance is secondary to the bibliophile mystery, so if you're here purely for swoon, calibrate expectations. Readers who love *The Midnight Library* or *Mr. Penumbra's 24-Hour Bookstore* will feel immediately at home.

BookTok has been absolutely feral about this one, and honestly? The hype is justified — though maybe not for the reasons you'd expect. When the Moon Hatched by Sarah A. Parker isn't the kind of romantasy that hits you fast and easy. The world-building alone is worth the price of admission: when dragons die, they drift skyward and become the moons, and sometimes those moons fall back to earth in catastrophic events called moonfalls. That premise is genuinely unlike anything else in the genre right now. Raeve is an assassin with missing memories fighting a tyrannical regime, and Kaan is a grief-hollowed ruler wearing a melted crown, searching for something that might finally quiet the ache inside him. Their paths collide in a notorious prison, and things get complicated fast. The pacing is deliberately slow in places — if you need romantic tension to ignite by chapter five, this might test your patience. But if you're the kind of reader who wants to feel genuinely lost in a world that has its own mythology, its own gods, its own physics of death and sky, this is that book.
