Once Upon a Broken Heart is the first entry in Stephanie Garber's #1 New York Times bestselling series, following Evangeline Fox as she strikes a dangerous bargain with the immortal Prince of Hearts — trading three kisses to stop her beloved's wedding, only to find the price far darker than she imagined. Atmosphere, premise, and a genuinely unpredictable plot power the novel's devoted readership, with Kirkus Reviews and Publishers Weekly praising its thematic depth and "exquisitely imagined worldbuilding." Readers who thrive on dark-fairytale romance and morally ambiguous supernatural figures will find it engineered for their tastes, though those who prize tightly constructed fantasy systems and restrained prose may find Garber's maximalist approach frustrating.
Is it worth reading?
For readers drawn to dark-fairytale fantasy romance, Once Upon a Broken Heart delivers on its core promise: an intriguing premise built around a dangerous bargain, a plot Kirkus Reviews credits with "welcome surprises," and what Publishers Weekly calls Garber's "exquisitely imagined worldbuilding and her trademark heady romance." Fellow #1 New York Times bestselling author Isabel Ibañez describes it as "edgy, dark, and gorgeously written" and "heart-pounding, fresh, and addictive." The key caveat, per Kirkus, is that the writing can veer from clever to overly verbose, and the fantasy world-building is unevenly developed — so readers who prioritize tightly constructed fantasy systems and restrained prose may find Garber's maximalist approach more frustrating than immersive.
Similar books
Readers who enjoy Once Upon a Broken Heart tend to gravitate toward other dark, lushly written fantasy romances. V.E. Schwab's The Invisible Life of Addie LaRue shares the theme of a desperate bargain with an immortal figure and Schwab's signature atmospheric prose. Amber V. Nicole's The Book of Azrael and Kerri Maniscalco's Kingdom of the Feared both deliver the morally complex supernatural romance and dark-fairytale energy that define Garber's appeal. Rachel Gillig's One Dark Window offers a similarly immersive fantasy world with a dangerous, morally ambiguous supernatural presence. For readers drawn to the fairytale retelling angle, Rachel Hochhauser's Lady Tremaine explores classic archetypes through a fresh, character-driven lens.
Who should read this?
Once Upon a Broken Heart is engineered for readers of young adult fantasy romance who love dark-fairytale premises, morally ambiguous supernatural figures, and emotionally driven heroines. Flatiron Books targets the novel at ages 13–18, and it is specifically well-suited to fans of lush, atmospheric prose and heady romance — the same readership that made the Caraval trilogy a global phenomenon. Existing Garber fans will appreciate the expansion into the mystical North and the foregrounding of the Fates, while newcomers to her fiction will find it a self-contained, accessible entry point. Those who prioritize tightly constructed fantasy systems or restrained prose are less likely to find it satisfying.
What age is it for?
Best for readers ages 13 and up. Flatiron Books targets the novel at ages 13–18, and Amazon's grade-level designation of grades 7–9 positions it at the younger end of young adult fiction. The dark-fairytale content — including a bargain with a lethal immortal figure and themes of heartbreak and dangerous consequences — suits the maturity range of teen readers without requiring prior familiarity with Garber's Caraval universe.
About Stephanie Garber
Stephanie Garber is an American author of young adult fiction known for the Caraval and Once Upon a Broken Heart series, which are interconnected trilogies.
What are the main themes?
Kirkus Reviews credits Once Upon a Broken Heart with well-rounded thematic substance, noting that "the themes of love, the power of story, family influence, and holding onto belief are well rounded and add depth." The concept of the Fates as a functioning religious system within the world is singled out as a source of genuine thematic interest. At its core, the novel asks what lengths someone will go to for a happily ever after — a question it filters through the dark-romantic tradition of morally complex fairytale storytelling.
How diverse is the cast?
Kirkus Reviews notes that Evangeline and several other central human characters read as White, with Luc described as having brown skin. Broader diversity is present among the fantasy races of the world rather than in the primary human cast — a pattern Kirkus flags as a notable limitation of the novel's representation. It is a considered observation from a major review outlet rather than a fringe complaint.

Summarize this book

Once Upon a Broken Heart follows Evangeline Fox, a young woman whose lifelong faith in true love is shattered when Luc — the man she loves — announces he will marry her stepsister Marisol. Desperate, she strikes a bargain with the Prince of Hearts, one of the immortal beings known as Fates: three kisses, given at times and places of his choosing, in exchange for his help stopping the wedding. What unfolds is a dark, magical journey set partly in the mystical North of Garber's Caraval universe, in which Evangeline discovers the Prince of Hearts wants far more than she pledged — and the outcome will be either the greatest happily ever after, or the most exquisite tragedy. The novel is the first in a four-book series and is written to be fully accessible to readers new to the Caraval universe.
