Plot Summary
Orphaned Origins and Awakening
Josephine "Jo" Doe wakes in a morgue, realizing she's died and become something other—ghost, vampire, and outcast. Her only anchor is her little brother, Thad, whom she's protected since they were found as children with no memory of their past. Jo's feral instincts and fierce love for Thad drive her to survive on the streets, but a violent encounter awakens her supernatural powers. She discovers she can become intangible, possess others, and, after a vengeful act, craves blood. Her transformation is both a curse and a liberation, setting her on a path of self-discovery and separation from the only family she's ever known.
Ghost, Vampire, Outcast
Jo's new existence as a ghostly vampire forces her to leave Thad in the care of a loving foster family, believing he's safer without her. She haunts his life from afar, torn between longing and the knowledge that her presence brings danger. As Thad thrives, Jo's loneliness deepens, and she becomes a mythic figure among the city's vulnerable, a shadowy protector and avenger. Her powers grow, but so does her isolation, and she clings to mementos of her lost life, haunted by the choices she's made and the hunger that defines her.
The Møriør Assemble
Across dimensions, the Møriør—an alliance of primordial immortals—awaken and gather, led by the enigmatic Orion. Rune Darklight, a half-demon, half-fey assassin, is tasked with hunting the soothsayer Valkyrie, Nïx, whose machinations threaten to upend the balance of power. Each Møriør seeks something from Earth, and Rune's own past as a slave, whore, and killer shapes his cold, detached approach to life and love. The stage is set for an Accession, a mystical event that will force all immortals into conflict.
Bourbon Street Encounters
Jo, now known as Lady Shady, stalks the night, punishing predators and searching for answers about her nature. Her path crosses with Rune, whose sexual exploits and supernatural allure draw her attention. Their first encounter is a battle of wits and wills, each recognizing the other as something unique and dangerous. Jo's curiosity and Rune's arrogance spark a volatile attraction, but both are wary—she of his poison, he of her unpredictability. Their banter is laced with challenge, desire, and the promise of something neither has ever known.
Predator Meets Predator
Rune and Jo's mutual fascination escalates as they test each other's boundaries. Jo's theft of Rune's cherished talisman provokes a confrontation that turns violent, then intimate. When Jo bites Rune, drinking his forbidden baneblood, they experience a connection that shatters their defenses. For the first time, Rune's poison doesn't kill, and Jo is transformed by his taste. Their encounter is both a battle and a surrender, leaving them both changed and craving more. The rules of their world no longer apply, and a dangerous new bond is forged.
Blood, Sex, and Secrets
The aftermath of their bite leaves Rune and Jo reeling. Their physical attraction is undeniable, but trust is elusive. Rune, ever the secrets master, fears Jo has stolen his memories, while Jo grapples with the consequences of her hunger and the taboo of their union.

The threat of betrayal and the specter of past wounds haunt them, but neither can resist the pull of the other.
The Thief and the Archer

Jo, however, is no ordinary captive—her resilience and wit match his every move. Their battle of bodies and minds blurs the line between torment and ecstasy, and both are forced to confront the truths they hide. In the end, it is vulnerability, not victory, that brings them closer, as they share a kiss that is both a promise and a surrender.

Plot Devices
Dual Protagonist Structure
The narrative alternates between Jo and Rune, allowing readers to experience both the external action and the internal struggles of each character. This dual structure deepens the emotional impact, highlighting the ways their pasts shape their present choices and the obstacles they must overcome to find connection. The interplay of perspectives creates tension, empathy, and a sense of inevitability as their stories converge.
Blood as Connection and Memory
Blood is both a literal and symbolic link between Jo and Rune. Their bites not only provide sustenance and pleasure but also transmit memories, pain, and understanding. This device allows for the gradual revelation of backstory, the deepening of intimacy, and the blurring of boundaries between self and other. Blood becomes a metaphor for vulnerability, trust, and the possibility of healing through shared experience.
The Accession and Immortal Politics
The Accession serves as both backdrop and catalyst, forcing all immortal factions into conflict and cooperation. The looming war, the gathering of armies, and the machinations of leaders like Nïx and Orion create a sense of urgency and high stakes. The political intrigue, betrayals, and shifting loyalties mirror the personal struggles of the protagonists, reinforcing the story's themes of power, choice, and the cost of survival.
Memory Loss and Recovered Identity
Jo's lost memories and gradual recovery of her origins drive much of the plot's emotional arc. Flashbacks, dreams, and the transmission of memories through blood allow for a layered exploration of identity, trauma, and the possibility of change. The device of amnesia heightens suspense, deepens empathy, and underscores the story's central question: can we choose who we become, or are we forever shaped by our past?
Vows and the Lore
Vows to the Lore are unbreakable, shaping the choices and fates of the characters. The tension between desire and duty, freedom and obligation, is embodied in the use and abuse of vows. This device raises questions about agency, trust, and the power of words to create or destroy. The breaking and remaking of vows mirror the characters' journeys toward self-acceptance and authentic connection.
Power as Both Gift and Curse
Jo's powers—ghosting, telekinesis, blood-drinking—are both a source of strength and a barrier to intimacy. The story explores the double-edged nature of power, the fear of being used or hunted, and the longing for acceptance. The evolution of Jo's abilities parallels her emotional growth, culminating in the choice to use her power for love, not just survival.
Analysis
Sweet Ruin is a dark, sensual, and emotionally charged exploration of trauma, transformation, and the redemptive power of love. At its core, the novel is about two broken souls—Jo, the feral survivor desperate for connection, and Rune, the haunted assassin convinced of his own unworthiness—who find in each other the possibility of healing and hope. The story interrogates the cost of survival, the burden of memory, and the courage required to change. Through its supernatural lens, Sweet Ruin examines universal themes: the longing for family, the fear of abandonment, and the struggle to reconcile past wounds with present desires. The use of blood as both a literal and metaphorical bond underscores the risks and rewards of intimacy, while the backdrop of immortal war amplifies the stakes of personal choice. Ultimately, the novel argues that destiny is not a prison, but a possibility—one that can only be realized through vulnerability, forgiveness, and the willingness to choose love, again and again. In a world where power isolates and wounds run deep, Sweet Ruin offers the radical hope that even the most broken can be made whole, not by fate, but by the choices we make and the bonds we forge.
