A siren with a magical debt bracelet must reconnect with the fae king who knows her past. They race to stop a plot snatching fae warriors, finding glass caskets and whispers of an ancient evil.
Callypso Lillis, Callie, lives in the human world, running a shop and avoiding her past. Black beads on her left arm represent favors owed to Des, the dangerous Fae king of the Night. These beads are magical IOUs, disappearing only with repayment or death. One night, Des, the Bargainer, appears in her bedroom, demanding she come to the Otherworld. He starts collecting her favors, beginning with a kiss. Callie is cautious, remembering their complicated past and the emotional pain he caused seven years ago when he ended their relationship. Despite her worry, she feels drawn to him again.
In the Otherworld, Callie learns the real reason for Des's sudden return. Fae warriors are disappearing, and their female partners are found dead, encased in glass caskets, each holding a child. Des believes an ancient evil is behind these disappearances and needs Callie's siren abilities to investigate. Her siren song can make others reveal truths, making her valuable. Callie, though hesitant to get involved in Fae politics, agrees to help, partly from duty and partly because of her feelings for Des.
Callie and Des start their investigation, visiting crime scenes and questioning witnesses. They find that a shadowy figure or group is taking the missing Fae, and the women return with signs of magic. During their search, Des continues to 'collect' Callie's favors. These range from chaste kisses to more intimate acts, slowly reigniting their intense connection. Callie struggles with her mixed feelings, still hurt by his past abandonment but unable to deny her attraction. She also notices changes in Des, suggesting a deeper vulnerability beneath his confident exterior.
Their investigation leads them to a lesser Fae involved in the disappearances. Using Callie's siren song, they get information, learning the Fae were targeted for their magic. During this encounter, they find a jade coin, a powerful magical artifact that seems key to the kidnappings. The coin has dark energy and suggests a larger, more sinister plot. This discovery confirms they face a strong opponent, pulling Callie further into the dangerous Fae underworld.
As they investigate, Callie's traumatic past resurfaces. A sadistic Fae called the Thief captured and tortured her when she was younger, leaving her deeply scarred. Des, seeing her pain, talks about his own history and his long fight against ancient evils. He reveals the current threat might connect to a powerful, ancient Fae entity known as the King of the Night, the original Bargainer, thought to be dead. This adds danger and urgency to their quest.
To get more information, Callie uses her siren song on a powerful magical artifact, causing a vision. This vision shows the villain's true goal: to harvest the magical essence of Fae warriors to awaken an ancient, evil entity called the Sleeping King. The women in glass caskets are sacrifices, and their children are meant to be vessels for the awakened entity. The disturbing vision shows the immense stakes and the enemy's cruelty. This experience deeply affects Callie, strengthening her resolve to stop the villain.
With new information, Callie and Des track down the villain, an ancient Fae servant of the Sleeping King. They fight hard, but the enemy is stronger and smarter than expected. During the fight, Callie's siren abilities are pushed to their limit, and Des uses his power as the Bargainer to protect her. They have to retreat, barely escaping capture. This encounter shows the great danger they face and their adversary's strength.
After their narrow escape, Des finally tells Callie why he left seven years ago. He reveals he was fighting the same entity now threatening the Otherworld and had to break ties with Callie to protect her. He knew she would become a target if connected to him. He also reveals the black beads on her arm are not just favors, but a magical tether, letting him sense her and keep her safe even when they were apart. This confession finally gives Callie the answers she needed.
With the full threat understood and their relationship mended, Callie and Des plan to stop the Sleeping King from fully awakening. They realize they can't face this ancient evil alone and start gathering allies from across the Otherworld, including other Fae lords and powerful magical beings who understand the situation's seriousness. Callie's abilities, combined with Des's strategic mind and power, become central to their plan. They prepare for a final fight, knowing the Otherworld's fate depends on them.
Callie and Des, with their new allies, attack the Sleeping King's forces. The battle is fierce, with powerful magic clashing. Callie uses her siren song to weaken the enemy, while Des uses his full power as the Bargainer. They face the awakened Sleeping King, a being of immense power. The fight is a desperate struggle for survival, with both Callie and Des pushing their limits. They work together; their combined strengths and allies prove important against such ancient evil.
Through planning, raw power, and Callie's abilities, they defeat the Sleeping King, sending him back to slumber or destroying him. The Otherworld is saved from destruction, but the victory has costs. Many Fae lives are lost, and the realm shows scars from the conflict. Afterward, Callie and Des confirm their renewed relationship, acknowledging their deep love. However, the events have opened new paths, and they realize their journey is not over, with new threats likely to appear.

The Mentioned

Callie's past trauma, particularly her experience with the Thief, is a main part of her character. The story shows how she deals with these deep scars, her hesitation to trust, and her path to healing. Des's understanding and support help her, as does her taking back her own power. The book shows that healing is not a quick process, but a continuous one of facing the past and finding strength.
“"My past was a shadow I couldn't outrun, but maybe, just maybe, I could learn to dance in its presence."”
The relationship between Callie and Des is rooted in love and the sacrifices made for it. Des's decision to leave Callie seven years ago, though painful, was a sacrifice to protect her from his world's dangers. Their rekindled romance is tested by current threats, forcing them to make more sacrifices for each other and the greater good. Their love helps drive their fight against the Sleeping King.
“"I broke your heart to save your life, Callie. It was the hardest thing I ever had to do."”
Both Callie and Des have great power—Callie with her siren song and Des as the King of the Night. The book explores the responsibilities that come with such power. Des's role as the Bargainer and protector of the Otherworld is a constant theme, as is Callie's struggle to use her abilities. They learn that true power is not just having it, but how it is used for justice and protection.
“"With great power comes a great many headaches, and a whole lot of enemies."”
The story explores destiny, especially through Des's inherited role as the Bargainer and the long conflict with the Sleeping King. However, it also emphasizes the power of individual choice. Callie chooses to help Des despite her past pain, and both characters make decisions that shape their future and the Otherworld's fate, showing that destiny can be influenced by free will.
“"We may be bound by fate, but our choices define our path."”
Magical IOUs representing favors owed to the Bargainer.
The black beads on Callie's arm serve as a crucial plot device, visually representing her debt to Des and driving much of their initial interactions. Each bead signifies a favor Des can call in, providing a structured way for their relationship to rekindle and for Des to subtly (and not so subtly) draw Callie back into his life and the Otherworld. They also serve as a narrative tool to reveal Des's deeper intentions and his protective instincts towards Callie, as they are later revealed to be a magical tether.
Callie's unique ability to compel others and reveal truths.
Callie's siren song is a powerful magical ability that functions as a key plot device for investigation and conflict resolution. It allows her to extract information from reluctant witnesses, uncover hidden truths, and disorient enemies during battles. This ability makes her indispensable to Des's mission and highlights her unique value. It also serves to empower Callie, allowing her to take an active and crucial role in the fight against the Sleeping King, rather than being a passive damsel in distress.
The chilling discovery of dead Fae women with children, revealing the villain's method.
The discovery of Fae women encased in glass caskets, each holding a child, is a horrifying and impactful plot device. It immediately establishes the dark and sinister nature of the antagonist and the high stakes of the conflict. These caskets provide critical clues about the villain's methods and goals – the harvesting of Fae essence and the use of children as vessels – pushing Callie and Des to understand the true depravity of the threat they face and motivating their urgent response.
A magical artifact linked to the Sleeping King's awakening.
The jade coin is a significant magical artifact discovered during the investigation. It acts as a tangible piece of evidence linking various disappearances and pointing towards the larger, more ancient evil. Its dark energy and specific magical properties provide clues about the Sleeping King's power and how his awakening is being facilitated. The coin serves as a physical representation of the growing threat and a focal point for the protagonists' efforts to understand and counter the enemy's magic.
