Plot Summary
Gilded Blood, Cursed Fate
In a land where demigods bleed gold and demons are cast as monsters, Alira, a knight orphaned by fate, is haunted by stories of wishing on a demon's heart. The demigods and demons are locked in a brutal, thirty-year war, their numbers dwindling, their gods silent. Alira's life is a cycle of violence and regret, her nights spent reliving the horrors she's endured and the friends she's lost. The only hope for peace is a marriage between the two races, but the cost is steep: a demigod bride for the Demon King's chosen. Alira, marked by her rare bloodline as a daughter of Venus, faces a destiny shaped by sacrifice, guilt, and the weight of a curse that resets her life with every death.
The Demon's Relentless Loop
Alira is ensnared in a time loop, forced to relive the week before her kingdom's fall, always ending at the hands of the Blood Knight—a merciless demon commander. Each reset is a fresh agony, her efforts to change fate futile. The curse is a punishment for her role in the war, a penance she cannot escape. As she watches her friends die over and over, hope withers. The loop is both a torment and a mystery, hinting at divine intervention and a lesson yet to be learned.
Flight Through Florum Shadows
Determined to break free, Alira flees her kingdom, seeking refuge in the cursed Florum forest. The woods are thick with old magic and memories of a childhood encounter with a demon boy—a meeting that sparked the war and left her with guilt she cannot shake. The forest is both sanctuary and grave, its silence a reminder of the lives lost and the innocence destroyed. Alira's journey is shadowed by regret and the fear that her actions have doomed not just herself, but all she loves. The forest's spirits seem to watch, holding secrets and warnings in their ancient roots.
A Demon by the Fire
In the heart of Florum, Alira meets Kalel, a demon apothecary whose presence is both dangerous and strangely comforting. Their conversation is tense, laced with suspicion and shared pain. Kalel's kindness unsettles Alira, challenging everything she's been taught about demons. He offers cryptic advice about fate and the futility of running, hinting at a deeper connection between them. The encounter stirs memories of the past and plants the seeds of something new—an uneasy alliance, a flicker of understanding, and the first cracks in the walls built by war and hatred.
Bargain of Sacrifice
Returning to her kingdom, Alira makes a bold decision: she volunteers herself as the bride for the demon peace treaty, revealing her rare lineage as a daughter of Venus. The king, weary and guilt-ridden, accepts her offer, recognizing the hope it brings for survival. The days that follow are filled with dread and preparation, as Alira confronts the reality of her sacrifice. The demons' acceptance of the bargain is swift, and the Blood Knight—Kalel—arrives to claim her. The stage is set for a union born of necessity, shadowed by old wounds and the threat of betrayal.
The Blood Knight's Choice
The Blood Knight, revealed as Kalel, is both executioner and savior. His hatred for Alira is personal, rooted in the massacre at Thornhall and the loss of his mother. Yet, beneath his cold exterior, there is a flicker of something more—recognition, regret, and a shared history that neither can escape. The marriage is sealed with a sacred oath, binding their fates and marking them as both enemies and partners. The ceremony is a spectacle of power and pain, witnessed by kingdoms eager for peace but hungry for vengeance.
Bound by Sacred Oath
The sacred oath that binds Alira and Kalel is more than a formality—it is a sharing of soul essence, a mark that ties their lives together. The ritual is exhausting, leaving Alira vulnerable and exposed. Kalel's care is cold but attentive, his actions driven by duty and a need to control. The dynamic between them is fraught with tension, desire, and the ever-present threat of violence. As they journey toward Devicit, the boundaries between captor and captive blur, and the true nature of their bond begins to emerge.
Scent and Submission
In the demon camp, Alira learns the rituals of scenting and submission, customs that both protect and humiliate her. Kalel's need to mark her is primal, a declaration of ownership that stirs conflicting emotions in them both. The physical closeness forced by these rituals awakens desires and vulnerabilities, complicating their relationship. The journey is harsh, the winter unforgiving, and the dangers—both external and internal—mount with every mile. Trust is a fragile thing, easily broken and desperately needed.
Thorns of Thornhall
Passing through the ruins of Thornhall, the site of the massacre that changed everything, both Alira and Kalel are confronted by the ghosts of their pasts. The pain of loss and the weight of guilt are palpable, fueling Kalel's desire for retribution and Alira's longing for forgiveness. Their conversations are confessions, each revealing wounds that have never healed. The truth of their shared history is a blade that cuts both ways, binding them in suffering and the hope of redemption.
Wolves and Warnings
The journey is interrupted by an attack from dire wolves, drawn by the scent of demigod blood. The chaos is deadly, and Alira is gravely wounded. Kalel's desperate act to save her—giving her his blood—breaks the curse's hold, but at a terrible cost. The intervention of ancient spirits and the appearance of a will-o'-the-wisp bring warnings from the gods, hinting at a fate that cannot be escaped. The message is clear: their union is dangerous, and the consequences will be dire.
Dragons at the Gates
As they approach Devicit, the party is attacked by dragons—beasts of legend, drawn to Alira's unique state between life and death. In a moment of crisis, Alira commands the dragons, revealing a power she never knew she possessed. The demons witness her strength and are forced to reconsider their hatred. The gates of Devicit open, and Alira enters a kingdom veiled in magic, her place among the demons both precarious and essential.
Devicit's Veiled Kingdom
Inside the magical veil of Devicit, Alira is introduced to a kingdom unlike any she has known—lush, vibrant, and filled with both beauty and danger. The palace is a place of intrigue, its halls haunted by the memories of war and the ambitions of those who would use Alira for their own ends. Kalel's role as both protector and jailer becomes more complicated, as old enemies and new allies emerge. The line between love and hate grows ever thinner.
Wedding of Ash and Gold
The wedding is a spectacle of tradition and violence, interrupted by an assassination attempt and the ever-present threat of devilstones. The ceremony is presided over by the ancient Krinsle, whose magic binds Alira and Kalel in a union that is both sacred and cursed. The kiss that seals their marriage is a defiance of the gods, a moment of connection that hints at the possibility of something more than survival. Yet, the dangers are far from over, and the cost of peace is steep.
The King's Last Dance
At the banquet and ball, Alira navigates the treacherous waters of demon society, facing scorn, envy, and the predatory interest of King Achill. Kalel's jealousy and possessiveness flare, revealing the depth of his feelings and the fragility of their alliance. The king's intentions are clear—Alira is a prize to be claimed, her power a threat and a temptation. The night is a dance of politics and passion, each step fraught with risk.
Gardens of Penance
In the moonlit gardens, Alira and Kalel confront their desires and their guilt. Their intimacy is both a balm and a torment, each touch a reminder of what they have lost and what they might yet find. The act of knotting—demon mating—binds them physically and emotionally, a union that is as much about penance as it is about pleasure. The garden becomes a place of confession, where secrets are shared and the possibility of forgiveness is glimpsed.
Confessions in Moonlight
The truth of their shared past is finally unveiled: Alira was the girl who tried to help Kalel as a child, and her actions—however innocent—set in motion the tragedy that shaped them both. Kalel's confession is a wound reopened, but also a chance for understanding. Their connection is undeniable, forged in pain and longing. The gods' games are cruel, but in the moonlight, Alira and Kalel find a moment of peace, a fragile hope that love might yet grow from the ashes.
The Curse Unveiled
The true nature of the curse is revealed: it was placed by Pluto, god of the underworld, in response to a prayer and a plea for vengeance. The time loop was both punishment and protection, a way to keep Alira alive until she could be freed by Kalel's blood. The gods watch closely, their motives inscrutable, their warnings dire. The story is not just one of mortals and demons, but of deities playing with fate, love, and the cost of forgiveness.
Once Upon a Demon's Heart
In the end, Alira and Kalel are bound by more than oaths and curses—they are united by the scars they share, the love that grows in spite of everything, and the hope that peace might be possible. Their journey is far from over, the dangers still looming, but in each other, they find the strength to face whatever comes next. The gods may yet have their say, but for now, a demon's heart and a demigod's hope beat as one.

Plot Devices
Time Loop Curse
The time loop is the central narrative device, trapping Alira in a cycle of death and resurrection that forces her to confront her actions and the consequences of war. Each reset is an opportunity for change, but also a reminder of the futility of violence and the need for forgiveness. The curse is both a punishment—inflicted by Pluto at Kalel's request—and a shield, keeping Alira alive until she can be freed by love and sacrifice. The loop structures the story, allowing for deep character exploration and the gradual revelation of secrets.
Dual Perspective and Unreliable Memory
The narrative alternates between Alira and Kalel, offering insight into their inner worlds and the ways in which trauma distorts memory and perception. The unreliable nature of their recollections—especially regarding their childhood encounter—creates tension and suspense, as the truth is only revealed through confession and confrontation. This device deepens the emotional impact and underscores the theme of misunderstanding and reconciliation.
Sacred Oath and Scenting Rituals
The sacred oath that binds Alira and Kalel is both a plot mechanism and a metaphor for the ties that bind enemies and lovers. The rituals of scenting and submission are used to explore power dynamics, vulnerability, and the blurring of boundaries between self and other. These customs serve as both protection and humiliation, forcing the characters to navigate intimacy and trust in a world that seeks to destroy them.
Divine Intervention and Foreshadowing
The presence of the gods—Pluto, Mercury, Venus—is felt through omens, visions, and direct intervention. Their actions foreshadow key events, provide warnings, and shape the characters' destinies. The will-o'-the-wisp, the dragons, and the Krinsle are all manifestations of divine will, their appearances signaling turning points in the narrative. The gods' games are a constant reminder that mortal choices are both free and fated.
Symbolism of Blood, Flowers, and Fire
Blood—gilded, spilled, consumed—is a symbol of both life and death, guilt and redemption. Flowers, especially peonies, represent innocence lost and the possibility of renewal. Fire is both destruction and purification, a force that both scars and cleanses. These symbols recur throughout the story, reinforcing the emotional and thematic arcs.
Analysis
Once Upon a Demon's Heart is a dark romantasy that uses the trappings of epic fantasy—war, magic, gods, and monsters—to explore the psychological scars left by violence and the possibility of redemption. The time loop is both a literal and metaphorical device, forcing the protagonist to relive her mistakes until she can confront the truth of her actions and seek forgiveness—not just from others, but from herself. The relationship between Alira and Kalel is a study in trauma bonding, enemies-to-lovers tension, and the slow, painful process of healing. The story interrogates the narratives we inherit—about good and evil, us and them—and the ways in which those stories perpetuate cycles of hatred. By centering the emotional arc on confession, vulnerability, and the willingness to change, the novel suggests that peace is not achieved through victory, but through understanding and sacrifice. The gods' interference is a commentary on the arbitrariness of fate and the need for agency in the face of suffering. Ultimately, the book is a call to break the cycles that bind us, to choose empathy over vengeance, and to believe that even the most broken hearts can find hope.
