What is Once Upon a Broken Heart book about?
Once Upon a Broken Heart is a young adult fantasy romance spin-off that exists within the same magical universe as Garber’s Caraval series. While Caraval follows sisters Scarlett and Tella navigating a dangerous game run by the mysterious Legend, the new series centers on Evangeline Fox, a protagonist who makes a fateful bargain with the Prince of Hearts himself.
Plot summary
Evangeline Fox stumbles into a deal she can’t refuse: three kisses from the Prince of Hearts, whose touch is lethal to mortals unless true love is involved. Her motivation is deeply personal—she wants to stop an upcoming wedding and heal her own fractured heart. The stakes escalate quickly, as the Prince of Hearts’ kisses carry deadly consequences for those who lack genuine love. The story blends romantic yearning with high-stakes magical consequences, a signature combination that Garber has built her reputation on.
Main characters
Evangeline Fox serves as the heart of the new series—a character driven by desperation and desire in equal measure. Opposite her stands the Prince of Hearts, a figure whose deadly kiss mechanic adds genuine suspense to what might otherwise be a straightforward romance. Readers familiar with Caraval will recognize cameos from the original cast, though the focus shifts firmly to Evangeline’s story.
Unlike Caraval, where multiple characters vie for attention, Once Upon a Broken Heart pins its emotional core on two characters and their impossible bargain. The tradeoff: less ensemble complexity, more concentrated romantic tension.
Connection to Caraval
The connection runs deeper than shared setting. Both series take place in a world where magic operates through games, wishes, and deadly bargains. Legend, the enigmatic master of Caraval, appears in Once Upon a Broken Heart, hinting at larger forces at work. The Prince of Hearts himself is woven into Caraval’s mythology, which means devoted readers will spot connections and foreshadowing that enrich both series.
Is Once Upon a Broken Heart a spicy book?
This is one of the most-asked questions about the series, and it deserves a direct answer grounded in what reviewers have documented.
Spice level details
Once Upon a Broken Heart is rated moderate for sexual content. According to Rated Reads, which breaks down books scene by scene, the first book features several kissing scenes and mild references to intimacy, but explicit sexual encounters are absent. The profanity level is minimal—Rated Reads notes only one instance of mild language and one use of a deity’s name in vain.
The romance operates primarily through emotional intensity and the threat of the Prince of Hearts’ lethal kiss rather than physical explicitness. Garber’s signature flowery, detailed kiss scenes carry the romantic weight, consistent with her style across Caraval.
Comparison to Caraval
The Caraval trilogy leans toward romantic tension over physical content—Scarlett and Tella’s stories feature desire and longing, but the games and mysteries take narrative precedence. Once Upon a Broken Heart shifts that balance somewhat, giving the romance more page time and emotional stakes.
“Rated: Moderate. There’s hardly any profanity, just one use of mild language and one use of the name of Deity in vain. Sexual content is fairly minimal.”
— Rated Reads (Content Rating Site)
18+ content warnings
No 18+ content has been documented for Once Upon a Broken Heart. The kissing scenes are described in detail by community reviewers as “flowery” and evocative rather than explicit. There are no confirmed reports of graphic sexual scenes, nude scenes, or content that would typically trigger adult-only ratings.
Parents looking for granular content breakdowns should note that Book 1 has been reviewed in detail, but Books 2 and 3 in the series lack independent scene-by-scene reviews at the time of writing.
Is Once Upon a Broken Heart 18+?
The short answer is no—Once Upon a Broken Heart is not classified as adult content. However, the age recommendation varies slightly depending on the source.
Age rating analysis
Multiple sources converge on a 13–14+ recommendation. The Story Sanctuary lists it for ages 14 and up. The Screenwise App, a parent-focused review platform, describes it as perfect for “13 or 14 and up” and notes it offers “high-stakes fantasy and intense romance without the R-rated.” Walmart’s listing for the three-book collection specifies ages 14+.
The Caraval series, by comparison, carries a 13–18 recommendation from She Reads Romance Books. Both series operate in similar territory: YA fantasy romance with kissing-focused intimacy, mild profanity, and magical stakes.
Kid and parent reviews
Goodreads community reviews include discussions from readers who identify as teenagers and parents. A Goodreads Q&A thread specifically asks whether a 13-year-old can read the book, with community responses confirming appropriateness for that age, citing detailed kiss scenes but absence of explicit content. The Story Sanctuary review notes the main characters are white with no diverse representation flagged.
“Perfect for 13 or 14 and up. It hits that ‘sweet spot’ for middle and high schoolers who want high-stakes fantasy and intense romance without the R-rated.”

Which one should I read first, Caraval or Once Upon a Broken Heart?
This is a common point of confusion, and the answer depends on what experience you’re looking for.
Reading order recommendations
Stephanie Garber has stated that the two series share a universe but are designed to be read independently. The Caraval trilogy (2017–2019) introduces the world, its magical rules, and characters who appear in Once Upon a Broken Heart. However, Once Upon a Broken Heart does not require prior Caraval knowledge to understand or enjoy.
The practical recommendation from most reviewers: if you prefer starting from the beginning of a universe, read Caraval first. If you discover Once Upon a Broken Heart and want to dive in immediately, you can do so without feeling lost.
Series connections
The connections between series are designed as Easter eggs rather than plot dependencies. Legend appears in Once Upon a Broken Heart, and the Prince of Hearts draws from mythology that Caraval established. But these appearances enrich rather than explain—the stories stand alone.
Reading Caraval first gives context and may enhance emotional payoff when familiar faces appear. Skipping Caraval lets you approach Once Upon a Broken Heart fresh, but some references may feel unearned or cryptic.
