Stephanie Garber built a devoted readership with the Caraval trilogy, and Once Upon a Broken Heart is the beginning of a new chapter in that universe — same world, new protagonist, and a central figure who has haunted the edges of the Caraval books long enough to warrant his own story. Jacks, the Prince of Hearts, is finally center stage. He is exactly as magnetic and infuriating as promised.

Evangeline Fox and the Deal She Shouldn’t Make

Evangeline is a girl who believes in love stories. She has grown up in her family’s shop, surrounded by fairy tales, and she has shaped her sense of self around romantic belief rather than cynicism. When the boy she loves is about to marry someone else, and a god of heartbreak offers to help her stop the wedding in exchange for three small kisses at times of his choosing, she says yes.

Garber establishes Evangeline’s voice quickly and well. She is warm and impulsive and not stupid — she knows the deal is dangerous, she makes it anyway, and she spends the novel learning what dangerous actually means in this world. Her romantic idealism is both her most endearing quality and the lever that makes her vulnerable, and Garber handles that dynamic with real care.

Jacks: The Prince of Hearts, Fully Rendered

Jacks has always been most interesting as a figure slightly out of frame, and Once Upon a Broken Heart is the book that steps closer. He is a Fate — an ancient being for whom human emotion is a kind of weather to be observed and occasionally directed. He is also, unmistakably, not indifferent to Evangeline in ways he seems to find annoying.

The push-and-pull between them is the engine of the novel, and Garber writes it with the same lush, charged quality that characterized the Caraval romance. Jacks is not a good person, and the book does not ask readers to pretend otherwise. The appeal is in watching Evangeline navigate someone whose moral calculus is genuinely alien while still being legible as a kind of feeling.

The Caraval Universe Expands

The world-building that has gone into this series is evident in how naturally the new setting unfolds. A royal wedding, an ancient prophecy, a game being played by forces whose rules Evangeline can only partially see — Garber layers these elements with her characteristic atmospheric flair. The world has a fairy-tale heightened quality that is entirely her own.

Why YA Readers Will Love This

Caraval readers will find the things they loved about that series here — the immersive atmosphere, the romantic tension that keeps you reading long past when you planned to stop, the sense of a world where enchantment is genuinely enchanting. Once Upon a Broken Heart also introduces something slightly darker: Jacks is a more morally complex figure than Julian Marrero, and the stakes feel different.

For readers who want their fantasy with lush romanticism and a healthy dose of “I know this person is probably bad for me but I can’t look away,” this series is exactly right. The sequel cannot arrive fast enough.
