Plot Summary
Collision and Consequence
The story opens with a violent car crash: a family's world is shattered when a four-by-four collides with their car, leaving devastation and a driver who flees the scene. This event, witnessed only by the reader, sets in motion a chain of trauma and guilt that will ripple through generations. The survivor's fate, and the consequences of the driver's choice, become the unseen engine of the narrative, echoing in the lives of those who come after. The crash is not just a physical event but a metaphor for the sudden, unexplainable ruptures that haunt families and shape the psyche of children who grow up in the shadow of loss and abandonment.
Sleepless Nights Begin
Emma Averell, a successful lawyer, wife, and mother, is jolted awake by a sense of dread. She cannot sleep, haunted by the feeling that someone is in her house. Her insomnia is new and inexplicable, and as she checks on her children, she is gripped by a primal fear. The sleeplessness is not just physical but existential, a harbinger of something dark approaching. Emma's life, outwardly perfect, is already beginning to fray at the edges, and her inability to rest becomes a symbol of her growing anxiety and the legacy of trauma she carries.
Family Shadows Return
Emma's estranged sister, Phoebe, returns unexpectedly, summoning Emma to the hospital where their mother, Patricia, is dying after a self-inflicted injury. The sisters' relationship is fraught with resentment and unspoken pain, rooted in a childhood marked by their mother's madness. Phoebe's presence is both a comfort and a threat, forcing Emma to confront memories she has long buried. The return of the past, embodied in both Phoebe and their mother, destabilizes Emma further, as she is forced to reckon with the possibility that she is not as different from her mother as she wants to believe.
The Mother's Legacy
Patricia, once a loving mother, descended into psychosis around her fortieth birthday, muttering numbers and becoming violent. Emma, now approaching forty herself, is terrified of repeating her mother's fate. The sisters' childhood ended the night Patricia tried to suffocate Phoebe, an act Emma interrupted. Patricia's subsequent institutionalization left both girls adrift, their bond fractured by foster care and divergent paths. The fear of "bad blood" and inherited madness becomes Emma's obsession, coloring her every thought as her birthday looms.
Unraveling at Home
Emma's insomnia worsens, and her home life begins to deteriorate. Her husband, Robert, is resentful and distant, chafing at his role as a stay-at-home dad. Their daughter, Chloe, is rebellious and secretive, while young Will becomes withdrawn and troubled. Emma's car is vandalized, threatening notes appear, and she feels watched. The ordinary stresses of work and family are amplified by a sense of persecution and the suspicion that someone is trying to drive her mad. The boundaries between reality and paranoia blur as Emma's grip on her life weakens.
The Dreaded Birthday Approaches
As Emma's fortieth birthday nears, her anxiety becomes overwhelming. She is plagued by compulsive rituals—checking doors, staring out windows, muttering her mother's numbers. Her nights are filled with dread, and her days with exhaustion. The family plans a party she dreads, and every interaction feels loaded with hidden menace. Emma's sense of self is eroding, and she becomes increasingly isolated, unable to trust her own perceptions or the people around her.
Paranoia and Patterns
Emma experiences blackouts and lost time, finding evidence of actions she cannot remember—numbers scrawled on surfaces, disturbing recordings on her Dictaphone. Will's behavior grows more alarming; he draws pictures of a madwoman looming over his bed, echoing the trauma of Emma's own childhood. Emma's colleagues and friends begin to distance themselves, and her marriage teeters on the brink. The pattern of her mother's breakdown seems to be repeating, and Emma fears she is becoming a danger to her own children.
The Sister's Secret
Emma becomes convinced that Phoebe is manipulating her, feeding Will stories about their mother and sabotaging Emma's sanity. The sisters' relationship deteriorates into mutual suspicion and accusation. Phoebe's visits to their mother in the institution are revealed to be less about forgiveness and more about unresolved rage. Emma's paranoia grows, but the evidence is ambiguous—Phoebe could be a victim, a saboteur, or both. The question of who is gaslighting whom becomes central, as Emma's trust in her own mind collapses.
The Child's Drawings
Will's drawings become increasingly disturbing, depicting a woman with wild hair and a pillow, poised to smother a child. The images are eerily similar to the scene Emma witnessed as a child. Teachers and therapists are alarmed, and Robert begins to suspect Emma of harming their son. Emma, desperate to protect Will, is haunted by the possibility that she is unconsciously reenacting her mother's violence. The line between premonition and memory blurs, as Will's art seems to foretell disaster.
Marital Fractures
Emma's marriage unravels as Robert's resentment boils over. He pursues a business venture in secret, confides in Phoebe, and ultimately asks Emma to leave the house for the safety of the children. Emma is devastated, convinced that Robert and Phoebe are conspiring against her. The family fractures, and Emma is left alone, her career in jeopardy and her sanity in question. The sense of betrayal is total, and Emma's isolation becomes complete.
The Dictaphone Incident
Emma discovers that her Dictaphone, meant for work, is filled with recordings of her muttering her mother's numbers in a trance-like state. She has no memory of making them. Her secretary and boss are alarmed, and Emma is forced to take leave from work. The incident becomes a turning point, as Emma is forced to confront the possibility that she is losing her mind—or that someone is deliberately making her appear insane.
Accusations and Isolation
After her mother's death, Emma becomes the prime suspect in a possible murder investigation. The police, her husband, and even Phoebe question her version of events. Emma's children are kept from her, and she is accused of harming Will. Her professional reputation is destroyed by false online reviews, and she is fired. Emma is utterly alone, her reality undermined at every turn, and she begins to contemplate institutionalization for her own safety.
The Past Bleeds Forward
Emma's investigation into her mother's past reveals a pattern of trauma that transcends generations. She learns of a family curse, the "bad blood" that afflicts second children, and the possibility that her mother's madness was a form of premonition—a psychic echo of future violence. The boundaries of time blur, and Emma becomes convinced that the past and future are bleeding into each other, creating an endless loop of suffering. The concept of the ouroboros—a snake eating its own tail—becomes the central metaphor for the family's fate.
The Hospital Visit
Emma's visit to the institution where her mother died brings new revelations. She learns that her mother was not always catatonic, that Phoebe's visits were filled with anger, and that another patient, Sandra, witnessed Phoebe's cruelty. Emma's certainty about her own innocence wavers, as she confronts the possibility that she, Phoebe, or someone else could have killed their mother. The truth becomes ever more elusive, and Emma's sense of reality fractures further.
The Police Close In

Phoebe survives and, in a moment of lucidity, tells Emma that she saw someone else push her. The sisters reconcile, acknowledging their shared trauma and the ways they have hurt each other. Emma realizes that the true enemy is not within her family, but outside it—a force that has been manipulating events and feeding on their pain. The cycle of blame is broken, and the sisters begin to heal.
The Unseen Enemy
The true antagonist is revealed: Caroline, a nurse whose family was destroyed in the car crash that opened the novel, has been orchestrating Emma's downfall. Driven by a lifetime of resentment, Caroline has sabotaged Emma's life, killed her mother, and attempted to murder Phoebe. On the night of Emma's fortieth birthday, Caroline infiltrates the house, intent on killing Emma's family. Emma, wounded but determined, confronts Caroline in a violent showdown, saving her children and ending the cycle of vengeance.
The Night of Reckoning
The climactic night is a maelstrom of violence and revelation. Emma, stabbed and bleeding, fights her way through the house to save her children from Caroline. The confrontation is brutal and cathartic, as Emma finally breaks free from the legacy of fear and trauma. The police arrive, and Caroline is incapacitated, her reign of terror ended. Emma's survival is both literal and symbolic—a refusal to be consumed by the past.
Ouroboros: The Endless Loop
In the aftermath, Emma reflects on the nature of trauma, time, and fate. She realizes that her mother's madness was a form of premonition, a psychic wound inflicted by the violence yet to come.

She rebuilds her life, reconnects with her sister, and finds hope for her children. The story ends with the possibility of new beginnings, even as the shadows of the past linger.
Characters
Emma Averell
Emma is a successful lawyer, wife, and mother whose life is upended by insomnia and the return of her traumatic past. Driven by ambition and a desperate need for control, she is also deeply vulnerable, haunted by the fear that she will inherit her mother's madness. Emma's relationships—with her husband, children, and sister—are fraught with tension, shaped by her inability to trust herself or others. Her psychological journey is one of self-doubt, paranoia, and ultimately, resilience. Emma's arc is a struggle to break free from the generational cycle of trauma and to reclaim agency over her own fate.
Phoebe Bournett
Phoebe, Emma's older sister, is both a source of comfort and conflict. Marked by the trauma of their mother's violence, Phoebe is angry, defensive, and often cruel, but her actions are rooted in pain and a longing for connection. Her relationship with Emma is a tangle of love, jealousy, and blame. Phoebe's visits to their mother are driven by a need for closure, but also by unresolved rage. Ultimately, Phoebe's survival and reconciliation with Emma signal the possibility of healing and forgiveness.
Patricia Bournett
Patricia is the absent center of the novel—a woman destroyed by mental illness, whose actions haunt her daughters. Her descent into madness is both a personal tragedy and a generational curse, marked by compulsive rituals, muttered numbers, and violence. Patricia's legacy is one of fear and uncertainty, but also of love and sacrifice. Her madness is reinterpreted as a form of premonition, a psychic wound inflicted by the future. Patricia's story is a meditation on the limits of understanding and the power of trauma to echo across time.
Robert Averell
Robert is Emma's husband, a man who has sacrificed his career to support Emma's ambitions but grows increasingly bitter and distant. His resentment fuels the family's dysfunction, and his secretive behavior makes him a suspect in Emma's eyes. Robert's inability to communicate or support Emma deepens her isolation, and his shifting alliances with Phoebe and others exacerbate the family's fractures. Ultimately, Robert is revealed as flawed but not malicious—a man undone by his own disappointments.
Will Averell
Will, Emma's young son, is the emotional heart of the novel. Withdrawn and troubled, he becomes the unwitting vessel for the family's trauma, drawing pictures that echo the violence of the past and the threat of the future. Will's "fuzzy head" and visions are revealed to be a form of premonition, a psychic inheritance from his mother and grandmother. His survival is the ultimate victory, a sign that the cycle of trauma can be broken.
Chloe Averell
Chloe, Emma's teenage daughter, is caught between adolescence and adulthood, struggling with her own secrets and desires. Her affair with an older man and her anger at her parents' dysfunction reflect the family's instability. Chloe's relationship with Emma is strained but ultimately resilient, and her survival is a testament to the possibility of growth and change.
Caroline Williams
Caroline is the novel's true villain—a nurse whose life was destroyed by the car crash that opens the story. Consumed by resentment, she orchestrates Emma's downfall, manipulating events to drive her mad and destroy her family. Caroline's actions are both calculated and deranged, a manifestation of the novel's themes of trauma, fate, and the destructive power of the past. Her final confrontation with Emma is both a reckoning and a release.
Sandra
Sandra, a patient at the institution where Patricia lived, serves as a witness to the hidden dynamics between Phoebe and her mother. Her observations provide crucial evidence and insight, challenging Emma's assumptions and forcing her to confront uncomfortable truths. Sandra's marginalization reflects the novel's concern with who is believed and who is dismissed.
Nina Harris
Nina, a friend of Patricia's, offers Emma a bridge to the past and a source of understanding. Her memories and insights help Emma piece together the truth about her mother and the family's history. Nina's presence is a balm, a reminder that healing is possible even in the aftermath of tragedy.
Miranda Stockwell
Miranda, a client whose life is unraveling, serves as a red herring and a mirror for Emma's own fears. Her instability and threats add to the atmosphere of paranoia, but she is ultimately a victim of her own pain rather than a true antagonist.
Plot Devices
Generational Trauma and the Ouroboros
The novel's central device is the concept of generational trauma—a wound that is passed down, consciously or unconsciously, from parent to child. This is embodied in the image of the ouroboros, the snake eating its own tail, representing the endless loop of suffering and repetition. The narrative structure mirrors this, with events from the past bleeding into the present and future, and characters caught in cycles they cannot escape. The use of premonition, psychic echoes, and lost time blurs the boundaries of cause and effect, making the story a meditation on fate, agency, and the possibility of breaking free.
Unreliable Narration and Paranoia
Emma's perspective is deeply unreliable, shaped by insomnia, trauma, and manipulation. The reader is forced to question what is real and what is imagined, as Emma's paranoia infects the narrative. The use of blackouts, lost time, and ambiguous evidence keeps the truth elusive, heightening the suspense and psychological tension. The novel plays with the conventions of the domestic thriller, using Emma's unreliability to explore the nature of madness and the difficulty of distinguishing between victim and perpetrator.
Foreshadowing and Premonition
The motif of premonition runs throughout the novel, with characters experiencing visions, compulsions, and rituals that echo events yet to occur. The muttered numbers, the song, and Will's drawings all serve as warnings from the future, creating a sense of inevitability and dread. The narrative structure is circular, with the past and future constantly intruding on the present, and the climax is both a fulfillment and a breaking of the cycle.
Gaslighting and Manipulation
Emma's descent into madness is fueled by deliberate sabotage—false notes, vandalism, manipulated evidence, and the actions of an unseen enemy. The theme of gaslighting is central, as Emma's reality is undermined by those around her, and she is forced to question her own mind. The revelation of Caroline as the antagonist recontextualizes the entire narrative, exposing the ways in which trauma can be weaponized and the difficulty of discerning truth from deception.
Analysis
Insomnia is a masterful psychological thriller that explores the intergenerational transmission of trauma, the fragility of identity, and the terror of losing control. Through Emma's unraveling, the novel interrogates the ways in which the past shapes the present, and how the wounds of childhood can echo across decades. The use of unreliable narration, circular structure, and motifs of premonition and madness create a sense of claustrophobic inevitability, while the ultimate revelation—that the true enemy is not within the family but an outsider consumed by her own pain—offers a glimmer of hope. The novel's central lesson is that healing is possible, but only through confrontation, understanding, and the breaking of destructive cycles. Insomnia is both a
