Set in a remote mountain lodge called Idlewood, the novel follows Theodora “Theo” Scott—soon revealed to be Rowan Cahill—as she unravels the chilling truth about her past, her family, and the people around her. What begins as a tense holiday visit to her fiancé’s family estate becomes a harrowing descent into lies, trauma, and survival.

Summary
When Theodora “Theo” Scott accompanies her fiancé, Connor Dalton, to his family’s remote lodge in the Washington mountains, she’s anxious to make a good impression.
But something about Idlewood feels off from the moment they arrive. Snow blankets the estate in stillness, but beneath that quiet lies a tense and dangerous legacy.
Theo begins receiving anonymous warnings urging her to stay away from Connor. Her dreams are haunted by the image of an “antlered man,” and she starts recalling fragmented memories—flashes of fire, red scarves, and a woman’s scream.
As she meets Connor’s family—his intimidating grandmother Louise, cool-headed sister Alexis, volatile brother Trevor, and others—Theo senses judgment and secrets bubbling under the surface.
Her unease intensifies when she notices signs of surveillance, cryptic glances, and a conspicuously avoided fifth cabin on the property. Then, the facade begins to crack.
Theo discovers that her real name is Rowan Cahill.
She had been adopted after a traumatic childhood incident involving her biological mother, Mallory, who died under mysterious circumstances.
As memories resurface, Rowan realizes the antlered man from her dreams was Liam Dalton, Connor’s grandfather, who had a dangerous connection to her mother. The past is not just haunting her—it’s entangled with the Dalton family’s legacy.
Olena, a housekeeper, is found dead in the snow, wearing a red coat similar to Rowan’s.
It’s a clear case of mistaken identity, and Rowan suspects the death was no accident.
Trevor begins to blackmail her, revealing that he knows about her criminal past. Meanwhile, Nick and Magnus, close associates of the Daltons, show increasing signs of aggression and intent to silence Rowan permanently.
Rowan is drugged and zip-tied by Nick but escapes using a hidden knife and the help of Duchess, a loyal dog. Each act of violence against her only sharpens her resolve.
She reconnects with her adoptive father and learns the full extent of the deception she grew up under. Her life had been constructed on secrets and silence—now she wants answers.
As the family crumbles under its own web of lies, Rowan learns the truth: her mother was lured to Idlewood and murdered by Liam Dalton.
The death was covered up by the family, buried in snow and silence. Rowan’s abduction and attempted murder by Nick and Magnus confirm that the family will do anything to keep the truth buried.
In a powerful and violent climax, Rowan kills Nick in self-defense and confronts Magnus, who tries to bargain with her—offering secrecy in exchange for safety.
She refuses. The cost of truth is high, but Rowan is done being quiet.
By the end, she no longer sees herself as a passive victim but as the only one capable of pulling the truth into the light. While her mother’s body is never found, Rowan finds closure in reclaiming her name and her story.
Connor stands by her, physically and emotionally scarred but still loyal. The Dalton family, once cloaked in wealth and prestige, is exposed as broken, haunted, and culpable.
A Killing Cold closes on a note of hard-won peace. Rowan, no longer haunted by the past, but strengthened by it, looks toward a future of her own making. The snow begins to melt, but the scars remain—quiet, persistent reminders of the truths she refused to bury.
Characters
Rowan Cahill (Theo Scott)
Rowan, the protagonist, is a complex character shaped by deep trauma and repressed memories. Initially introduced as Theo Scott, she is engaged to Connor Dalton, yet she harbors a dark secret—her true identity as Rowan Cahill, the daughter of Mallory Cahill, whose death is at the heart of the novel’s mystery.
Rowan’s character evolves through the narrative as she uncovers buried truths about her past, including her horrific childhood memories of abuse and loss. Her struggle with dissociation and fractured memories highlights her emotional vulnerability, but over time, she becomes a fierce survivor.
Rowan’s transformation from a passive victim to an empowered figure is central to the novel’s theme of reclaiming one’s identity and confronting buried trauma. Her interactions with the Dalton family, especially her tense relationship with Connor, are crucial to her journey of self-discovery and healing.
Connor Dalton
Connor is initially portrayed as a loving and devoted fiancé to Rowan, though his background and family’s dark secrets remain largely obscured. As the story progresses, his connection to Rowan deepens, especially when he learns about her real identity.
He is not just a passive observer in the unfolding drama—Connor’s loyalty and emotional complexity come to the forefront when he chooses to stand by Rowan despite the revelations about her criminal past and the true nature of his family’s involvement in her mother’s death.
Although Connor’s character sometimes appears to be overshadowed by Rowan’s personal journey, his role as a moral anchor in her life and as a partner who chooses to support her through the harrowing events strengthens their relationship dynamic.
The Dalton Family
The Dalton family, particularly the matriarch Mrs. Dalton and her sons Trevor and Magnus, play pivotal roles in the unfolding tragedy at Idlewood. They are emblematic of privilege, power, and deep-seated secrets.
Mrs. Dalton represents the aristocratic, controlling figure who is both judgmental and protective of her family’s legacy. Her scrutiny of Rowan at the beginning of the novel sets the tone for the mistrust that pervades the family dynamics.
Trevor, Connor’s younger brother, is volatile and antagonistic, his actions reflecting the underlying tension and resentment within the family. Magnus, another key member, initially appears as a quieter figure but reveals his own capacity for manipulation and violence, particularly in the final chapters.
The Dalton family’s willingness to conceal the truth about Mallory Cahill’s death and their complicity in a range of immoral actions ultimately leads to their downfall, marking them as central antagonists to Rowan’s quest for justice.
Nick and Magnus
Nick and Magnus are characters who embody the more sinister aspects of the Dalton family’s dark legacy. Nick, in particular, serves as a direct physical threat to Rowan.
His actions are malicious, as he repeatedly assaults and attempts to silence her. His confrontation with Rowan in the shed is particularly revealing of his capacity for cruelty.
However, Magnus, while more composed, similarly reveals his involvement in covering up crimes and in manipulating others for personal gain. In the final chapters, both characters engage in brutal power plays that culminate in Rowan’s reclamation of power—particularly when she kills Nick in a fierce moment of self-defense.
Alexis Dalton
Alexis, Connor’s sister, is a more nuanced character. Initially, she seems aloof and distant, but as the story progresses, it becomes clear that she is not as complicit as the other Daltons in the darker aspects of the family’s past.
Alexis’s warning to Rowan—”Hurt my brother and I’ll turn on you”—carries a sense of protectiveness, but also foreshadows the eventual rupture in family loyalty. She struggles with her own demons, including her marriage to Paloma and the pressure from her family.
Alexis’s evolution from a passive observer to someone who offers Rowan subtle support adds depth to her character, though her own inner conflict about the family’s secrets is unresolved by the novel’s end.
Mrs. Louise Dalton
The matriarch of the Dalton family, Mrs. Dalton is a formidable and calculating figure. Her judgmental nature and overbearing personality contribute to the tension within the family, and her interrogation of Rowan early in the novel underscores the deep sense of scrutiny and distrust that governs the Dalton household.
She is not merely a figurehead but someone deeply invested in preserving the family’s image and wealth, regardless of the moral cost. Her involvement in the cover-up of Mallory’s death, along with her unyielding support of her family, highlights her role as a key antagonist in Rowan’s quest for truth.
Duchess the Dog
Duchess, a dog introduced later in the story, becomes a symbol of loyalty and survival for Rowan. In a novel filled with betrayal and deception, Duchess provides a moment of unconditional support for Rowan, particularly in moments when she needs to escape or gather strength.
The dog’s role, while secondary to the human characters, symbolizes the grounding force of loyalty and trust in an otherwise hostile environment.
Trevor Dalton
Trevor’s character, though a bit secondary to some of the more intense developments, is important in the context of the Dalton family dynamics. His antagonism toward Rowan at the beginning evolves into a more complicated relationship as he uncovers the truth about her identity.
His actions are erratic, and he often serves as a wild card in the unfolding drama. His eventual collapse into panic at the lodge showcases his vulnerability and fear, marking him as a character unable to fully control his own destiny or that of his family.
Themes
The Psychological Battle Between Identity and Trauma
One of the most profound and complex themes in A Killing Cold is the psychological struggle between a fractured identity and buried trauma. The protagonist, Theo (Rowan), grapples with the weight of a forgotten past, which emerges piece by piece throughout the narrative.
The tension between the person she is pretending to be in the present and the reality of who she once was creates a constant state of conflict. This theme goes beyond the typical “identity crisis”; it’s deeply intertwined with the trauma Rowan experienced in her childhood, particularly the brutal death of her mother, Mallory Cahill.
As her memories resurface, Rowan is forced to confront the truth about her biological heritage and her connection to the Dalton family, which she has long avoided.
The fear of facing her past, the terror of what it might reveal, and the overwhelming pressure of her present identity being challenged by these dark truths culminate in her ultimate act of reclaiming control over her narrative.
The Power of Secrets and the Legacy of Family
Another central theme in the novel is the destructive power of family secrets and their long-lasting impact on both individuals and entire dynasties. The Dalton family, with its wealth and influence, is a facade built on hidden truths, betrayals, and unresolved trauma.
From the very first chapters, there are hints that the family is deeply dysfunctional and that their external grandeur masks darker, buried realities. As Rowan digs deeper into the secrets surrounding her adoption, her biological mother’s death, and the strange dynamics within the Dalton family, it becomes clear that the family’s prosperity is built on lies and cover-ups.
The dangerous consequences of these secrets are felt by every member of the family, including Rowan, whose life is upended by revelations about her true identity and the sinister actions of those closest to her.
The theme of family secrets is not just about uncovering hidden truths, but about the toll these lies take on both the individual and the collective.
The Dalton family’s legacy, once viewed as powerful and untouchable, is ultimately shattered by the unveiling of its darkest truths, leaving a haunting mark on the characters and their fates.
The Struggle for Survival and the Transformation of Trauma Into Power
Survival is another overarching theme that shapes Rowan’s journey. In a literal sense, she must fight for her life against both the physical threats of the Dalton family members and the psychological ones that haunt her.
The narrative evolves from a psychological thriller into a harrowing tale of survival, with Rowan transforming from a terrified woman running from her past into a formidable force of justice.
This transformation is a direct response to the trauma she has experienced, particularly the terror of being stalked by those who want to silence her.
What begins as a struggle to escape and protect herself gradually shifts into a quest for vengeance and retribution. Rowan’s ability to survive becomes symbolic of her larger fight to reclaim her identity, her truth, and her autonomy from the people who have long controlled her fate.
The shedding of her victimhood is marked by several key moments of resistance, including her escape from Nick’s clutches, her eventual defeat of her assailants, and her refusal to accept a deal that would have kept her silence in exchange for safety.
This theme of survival shows how trauma, while crippling, can also fuel a person’s drive to overcome and take control, ultimately transforming pain into a source of strength.
The Burden of Justice and the Quest for Closure
Justice is a theme that runs throughout A Killing Cold, though its interpretation is multifaceted and complicated. For Rowan, justice is not just about seeking retribution against those who have wronged her; it is about confronting the legacy of violence, betrayal, and deception that has shaped her entire life.
As she uncovers the truth about her mother’s death and the crimes committed by the Dalton family, Rowan realizes that justice may never fully be achieved in the conventional sense.
The family’s atrocities are vast, and some mysteries—such as the location of her mother’s grave—remain unresolved.
However, justice in this context is not just about closure or legal retribution; it’s about reclaiming her voice and her agency. In the final chapters, Rowan chooses to expose the truth, regardless of the personal cost, and refuses to accept the complicity of the Dalton family as part of her story.
By doing so, she dismantles the corrupt power structures that have oppressed her. This theme raises important questions about what true justice looks like when faced with a broken and corrupt system—sometimes, it is not about the perfect resolution, but about the act of standing up and claiming your truth, regardless of the outcome.
The Interplay of Fear and Empowerment in Overcoming the Past
A final significant theme in A Killing Cold is the interplay between fear and empowerment, as Rowan confronts both the ghosts of her past and the immediate dangers posed by the Dalton family. The novel portrays fear not only as an emotion that paralyzes but as a catalyst for transformation.
Rowan’s fears—whether they involve her terrifying memories, the physical threat of the Dalton family, or her complex emotions surrounding her mother’s death—are constant, but they gradually shift from being a source of weakness to a driving force for empowerment. As Rowan faces the terrifying truth about her identity and the dark secrets of the family she’s become entangled with, she is simultaneously forced to confront her deepest fears.
Through this confrontation, she finds strength and resilience, ultimately becoming empowered by the very thing that once threatened to destroy her. This theme suggests that fear, while debilitating, can also be transformative when faced head-on, and through this process, Rowan learns to harness her fears and use them to fuel her resistance against the oppressive forces that have controlled her life.
