Once Upon a Broken Heart – Plot Summary and Character Guide

Once Upon a Broken Heart by Stephanie Garber marks the beginning of a sweeping spin-off series set within the beloved Caraval universe. First published in 2021, this young adult fantasy romance follows Evangeline Fox, a seventeen-year-old who believes firmly in true love and happy endings, until her world fractures when her first love becomes engaged to her stepsister. Desperate for a solution, Evangeline strikes a dangerous bargain with Jacks, the wicked Prince of Hearts—one of the immortal Fates—unwittingly setting herself on a treacherous path through curses, betrayals, and a slow-burn romance that defies expectation.

The novel introduces readers to a world where magic is both beautiful and deadly, where deals with Fates carry irreversible consequences, and where the line between hero and villain blurs with every turn of the page. Garber weaves together fairy-tale elements with high-stakes drama, creating a narrative that explores how love’s pain shapes those brave enough to walk through it.

What is Once Upon a Broken Heart About?

The story centers on Evangeline Fox, a passionate young woman working in her father’s curiosity shop in Valenda, a city within the Meridian Empire. Evangeline has always been a firm believer in destiny and the power of true love, spending her life chasing the fairy-tale ending she feels she deserves. Her world unravels when Luc Navarro, her first love and a wealthy young man she trusted completely, suddenly proposes to her stepsister Marisol Tourmaline.

Convinced that Marisol has used a love spell to steal Luc away, Evangeline seeks help from the only entity she believes might be powerful enough to intervene. She turns to Jacks, the unpredictable and dangerous Prince of Hearts, who is one of the immortal Fates—a being capable of rewriting fate itself. Jacks agrees to stop the wedding in exchange for three kisses, to be collected from Evangeline at times and places of his choosing, with recipients of his determination.

Jacks fulfills his end of the bargain by turning the entire wedding party to stone, freezing the ceremony in a moment of suspended horror. However, he immediately collects the first kiss and draws Evangeline into his schemes, pulling her northward toward the Magnificent North and a web of palace intrigues, ancient curses, and hidden agendas.

Plot Summary

Evangeline’s journey northward places her in a world of escalating danger and revelation. Despite her suspicions about Marisol, Evangeline chooses compassion and invites her stepsister to accompany her, a decision that proves consequential as the story unfolds.

In the Magnificent North, Evangeline confronts a series of life-threatening challenges involving curses, palace conspiracies, and figures such as Prince Apollo and his brother, whose relationship is marked by tension and rivalry. She repeatedly faces Jacks to give him the kisses she owes, each encounter deepening both the danger and the undeniable chemistry between them.

The narrative builds as Evangeline uncovers several devastating truths: Marisol has been using hidden magic and spells to undermine her; Jacks is pursuing his own mysterious agenda with her as a pawn; and Luc, missing for months, has been transformed into a vampire residing in the lair of the powerful being known as Chaos. Betrayals accumulate from all directions, forcing Evangeline to rely increasingly on her own judgment and strength rather than trusting others.

The story explores themes of love’s painful costs, the consequences of impulsive choices, and Evangeline’s evolution from a naive idealist believing in fairy-tale endings to a more complex character understanding that heroism requires sacrifice, self-awareness, and the courage to face difficult truths.

Key Ending Details (Spoiler-Free)

The novel concludes with Evangeline having learned uncomfortable truths about those closest to her, including Marisol’s secret involvement with magic, Jacks’ larger plans that extend far beyond their bargain, and Luc’s transformation into a being no longer entirely human. The ending balances tragedy with ambiguity regarding the possibility of a happy resolution, leaving readers uncertain whether the story will conclude in tragedy or a hard-won fairy-tale ending.

Is Once Upon a Broken Heart Connected to Caraval?

Once Upon a Broken Heart exists as a direct spin-off within the broader Caraval universe created by Stephanie Garber. The original Caraval trilogy introduced readers to a magical, game-like world where participants navigate a week-long experience of mystery and illusion, with the story focusing on Scarlett Dragna and her sister Tella. Jacks, the Prince of Hearts, appeared as a compelling side character in those novels, and his popularity with readers prompted Garber to develop his story further.

This spin-off series expands significantly on Jacks’ character, presenting him as the primary romantic interest rather than a secondary figure. The world-building remains consistent with the established Caraval mythology, featuring the same Fates, magical systems, and whimsical yet dangerous atmosphere. Settings include familiar locations like the Magnificent North, which connects the two series thematically and geographically.

Series Overview

The Once Upon a Broken Heart series comprises three main books and a companion novella. The first book, published in 2021, establishes Evangeline’s story and her complicated relationship with Jacks. The second book, The Ballad of Never After, continues expanding their narrative and introduces new challenges and revelations that build on the foundation established in the first novel.

The third book completes the arc begun with Evangeline’s desperate bargain, while the companion novella provides additional perspective on characters and events within the series. Each installment maintains the fairy-tale atmosphere, slow-burn romance elements, and high-stakes drama that characterize Garber’s writing style.

Reading Order

For readers new to the universe, Garber’s official recommendation suggests starting with the original Caraval trilogy for context, though this is optional. The Once Upon a Broken Heart series functions independently enough that readers can begin directly with Evangeline’s story without feeling lost. Those familiar with the first trilogy will recognize recurring elements and appreciate the deeper understanding of Jacks’ character that the spin-off provides.

The recommended approach for maximum enjoyment is to begin with Caraval, followed by the spin-off series, allowing readers to witness Jacks’ evolution from an intriguing secondary character to a fully developed protagonist with his own compelling narrative arc.

Who Are the Main Characters in Once Upon a Broken Heart?

The novel features a cast of complex characters whose motivations and allegiances shift throughout the narrative, creating a rich tapestry of relationships defined by love, betrayal, magic, and the grey areas between hero and villain.

Evangeline Fox

Evangeline Fox serves as the seventeen-year-old protagonist whose journey drives the narrative. She is characterized as determined, passionate, and impulsive—qualities that both serve and endanger her throughout the story. Initially, Evangeline believes firmly in the power of true love and the inevitability of happy endings, positioning herself as a classic fairy-tale heroine awaiting her destined prince.

Her encounter with Jacks and the subsequent trials she endures gradually transform her worldview. She develops greater courage, learns to question her assumptions, and gains self-awareness regarding her own flaws and the limitations of her idealism. Her growth arc involves understanding that love can be painful, that trust must be earned rather than assumed, and that she must sometimes rely on herself above all others.

Evangeline’s impulsiveness leads her into dangerous situations, but it also demonstrates her willingness to take action when circumstances demand courage. Her compassion extends even to those who may not deserve it, as evidenced by her decision to bring Marisol along on her northern journey despite her stepsister’s apparent betrayal.

Jacks, Prince of Hearts

Jacks ranks among the most compelling figures in Garber’s universe. As one of the immortal Fates, he possesses nearly godlike power over human emotions and destinies, yet he remains bound by rules and limitations that make him unpredictable rather than omnipotent. His nature is charismatic yet dangerous, with a reputation for cruelty that precedes him throughout the various kingdoms and territories of the world.

His motivations remain deliberately obscured throughout much of the narrative. He forms a slow-burn romance with Evangeline that defies simple categorization—neither entirely villainous nor traditionally heroic. Jacks explicitly refuses to change or apologize for who he is, articulating a philosophy that accepts his nature as fixed: “if you want the monster, you must learn to love it.” This stance creates tension with Evangeline’s hopes for redemption and happy resolution.

Throughout the series, Jacks reveals himself as pursuing grander plans that extend far beyond his bargain with Evangeline. His schemes span centuries and involve manipulations that position others—including Evangeline—as pieces in larger games. Yet his genuine connection with Evangeline remains uncertain, with readers questioning whether his feelings represent authentic emotion or simply another layer of manipulation.

Supporting characters include Luc Navarro, Evangeline’s first love whose sudden proposal to Marisol catalyzes the entire story, and who is later revealed to have become a vampire in Chaos’s lair; Marisol Tourmaline, the stepsister whose love potion use and secret magic practice create ongoing tension; and various palace figures including Prince Apollo, his brother, and the Empress, whose intrigues form the backdrop for much of the northern narrative.

Is Once Upon a Broken Heart Spicy?

The novel maintains a low to moderate spice level consistent with the young adult fantasy romance genre. The central romance progresses as a slow burn, with the primary physical expression being kisses—specifically the three kisses Evangeline owes Jacks—that occur throughout the narrative at increasingly significant moments.

The tension between Evangeline and Jacks generates considerable emotional intimacy and chemistry, with flirtatious danger forming a substantial part of their dynamic. Their interactions frequently carry romantic undertones, yet the focus remains on the emotional connection and the high-stakes nature of their bargain rather than explicit physical content.

Content Warnings and Spice Level

Readers should note several content elements present in the novel. The story involves themes of heartbreak and betrayal, with characters experiencing significant emotional pain related to romantic relationships and broken trust. Mild peril appears throughout, with various dangerous situations, curses, and life-threatening scenarios that maintain tension without reaching extreme violence.

The magic system includes elements such as love potions that affect character behavior, raising questions about consent and manipulation within romantic contexts. Characters face moral dilemmas and make choices with lasting consequences, including situations where trust is betrayed by those closest to the protagonist.

The overall tone balances whimsical fairy-tale atmosphere with genuine emotional stakes, creating a reading experience appropriate for teen audiences and older readers who appreciate young adult fantasy romance. The focus remains on the slow-burn romantic tension, the mystery of Jacks’ true nature and motivations, and Evangeline’s personal growth rather than explicit romantic content.

What Is Established Versus Unclear About Once Upon a Broken Heart

The Fairy-Tale Tradition in Once Upon a Broken Heart

Stephanie Garber’s work operates within the tradition of modern fairy-tale retellings and expansions, using familiar narrative structures as frameworks while subverting expectations and exploring darker themes that classical fairy tales often contained beneath their surface charm. Once Upon a Broken Heart exemplifies this approach by presenting a protagonist who begins believing in uncomplicated happy endings but must confront the reality that love and magic carry prices beyond simple transaction.

The protagonist’s journey from pauper to princess to fugitive to savior mirrors classic fairy-tale arcs while incorporating the moral complexity that distinguishes contemporary young adult fantasy from its more straightforward predecessors. Evangeline’s impulsive nature leads her into situations that test her assumptions about how fairy tales should unfold, forcing her to adapt rather than simply await rescue or fortunate coincidence.

Jacks represents the dangerous romantic figure common to fairy-tale traditions—the mysterious prince whose motives remain uncertain, whose power is both attractive and threatening, and who cannot be easily categorized as simply good or evil. His statement that he will not change or apologize for being what he is directly challenges the transformation arc that traditional fairy-tale villains sometimes undergo, instead presenting a character who demands acceptance of his nature as a prerequisite for any relationship.
