Summary
Olivia Bender is reeling from her sixth miscarriage when police arrive at her door with shocking news: her husband Park’s DNA has been linked to a murder suspect. But Park insists he has no children—until he’s reminded of his anonymous sperm donations years ago during college.
Olivia, devastated by both the miscarriage and the revelation of Park’s secret, begins to question everything about their marriage.
As detectives Osley and Moore dig deeper into the murder of Beverly Cooke, they discover the DNA match isn’t Park himself, but someone genetically close—likely a son.
Meanwhile, a mysterious young man watches the Benders from afar. He is one of Park’s biological children and is increasingly disturbed, driven by feelings of abandonment, resentment, and the belief that Olivia and Park represent the life he was denied.
The couple’s past is further complicated by the return of Perry, Park’s estranged twin brother. Olivia and Perry share a buried secret from their youth—an impulsive night after prom that led to an abortion Olivia never revealed.
Perry’s reappearance reopens old wounds and further destabilizes Olivia’s already fragile emotional state.
Park begins to uncover just how many children were conceived using his sperm—possibly over thirty. He’s horrified by the scope and begins to fear that more of his biological offspring may be involved in violent or unstable behavior.
Meanwhile, Olivia senses something is wrong at home. Objects are moved, things feel off, and she begins to suspect someone is entering the house when she’s not there.
As the investigators connect more murders with similar M.O.s, they realize the suspect—now identified as Ethan—is a serial offender. Ethan is one of Park’s donor-conceived sons and has been stalking Olivia for weeks.
He’s obsessed with her, seeing her as the “would-be mother” who could have given him the life he deserved. His stalking escalates to home invasion, subtle manipulations, and eventually direct threats.
Olivia, struggling with grief, betrayal, and fear, receives a prom photo from her past slid under her door—a clear sign Ethan knows her history. She finally confesses to Park about her past with Perry, shattering their remaining trust. Tensions among Olivia, Park, and Perry explode when Ethan finally confronts them in a violent home invasion. Holding Olivia at knifepoint, he rants about his stolen life and demands recognition and revenge.
In a climactic standoff, Perry distracts Ethan long enough for Park to intervene. A brutal struggle ensues, but the police arrive in time to subdue Ethan before he can kill Olivia.
The fallout is immense. Olivia and Park separate, unable to fully recover from the trauma and betrayals, though they remain on speaking terms. Perry leaves town again, knowing his presence is a painful reminder of the past.
Ethan is charged with Beverly Cooke’s murder and other crimes. Investigations reveal he was deeply troubled, a product not just of genetics but of emotional neglect and identity confusion. Public outrage erupts over the fertility clinic’s negligence in tracking and disclosing donor information. Legal scrutiny follows, highlighting ethical gaps in reproductive medicine.
In the epilogue, Olivia is finally finding peace. Though she never became a mother in the way she dreamed, she begins fostering a child and considers adoption, slowly healing and reclaiming her life.
A final twist—a proposed documentary about Ethan’s crimes and Park’s donor legacy—underscores society’s fascination with identity, nature versus nurture, and the hidden consequences of reproductive technology.

Themes
Exploration of Complex Psychological Identity Conflicts and the Struggles of Self-Realization
The narrative in It’s One of Us is heavily anchored in the concept of fractured identities, emotional instability, and the search for self. Ethan, the biological son of Park, is a character driven by resentment and confusion stemming from the lack of understanding of his own identity.
His deep emotional turmoil is tied to the absence of a father figure and the lack of nurturing in his formative years, compounded by the revelations that his biological father may be a murderer’s accomplice. The entire plot functions as a metaphor for the complexities of self-realization, as Ethan’s quest for answers about his origins spirals into obsession and violent tendencies.
His relentless pursuit to confront Park and Olivia speaks to the broader human struggle for recognition and the deep wounds caused by abandonment and emotional neglect.
The Ethics and Dilemmas of Reproductive Technologies and Genetic Legacy
A significant theme that permeates the novel revolves around the ethics surrounding sperm donation and its unforeseen consequences. Park’s involvement in sperm donation, originally a decision borne out of financial strain, becomes a devastatingly large part of his life’s legacy.
The novel meticulously explores the moral ramifications of anonymous sperm donations, particularly the lack of regulation and accountability at the fertility clinic. This oversight results in Park unknowingly fathering numerous children, some of whom grow up to develop psychological issues.
The implications of such a biological legacy are far-reaching—raising questions about the moral responsibilities of both the donors and the institutions that facilitate such practices. Park’s initial ignorance of his offspring’s existence only compounds the emotional burden of these secrets when they finally surface, thus highlighting the potential dangers of reproductive technologies when they are poorly managed or fail to consider the broader psychological impact on both the offspring and the donors.
The Weak Trust in Marital Relationships and the Collapse of Intimacy
At the heart of Olivia and Park’s troubled marriage lies the erosion of trust and the deep emotional rift caused by betrayal. The discovery of Park’s sperm donations and the revelation that he fathered a child implicated in a murder are devastating for Olivia, triggering feelings of betrayal that are not just related to the infidelity of sperm donation, but also to the long-standing deception surrounding their infertility struggles.
Olivia’s sense of self and her understanding of their shared history shatters, leading her to question the authenticity of her relationship with Park. The novel delves into the intricacies of this broken trust, revealing how the smallest secrets, when uncovered, can unravel the very fabric of a marriage.
Olivia’s emotional journey, marked by jealousy, anger, and mourning, reflects the fragile nature of marital intimacy and the difficulty of rebuilding trust once it has been betrayed.
Psychological and Emotional Consequences of Trauma and Loss on Mental Health
The theme of trauma and its impact on mental health is explored through the various characters’ experiences, particularly Olivia and Ethan. Olivia’s ongoing miscarriages and the emotional trauma she endures from her fertility struggles are compounded by the revelations of Park’s past, leading her to spiral into deeper emotional instability.
Her miscarriages, the loss of potential motherhood, and the emotional scars of her past decisions (such as the abortion after prom night) shape her psychological state. Similarly, Ethan’s emotional disturbances are deeply rooted in the trauma of growing up without a father and the psychological effects of abandonment.
The novel paints a bleak portrait of how unresolved trauma can affect one’s mental health, often manifesting in ways that are destructive not only to the individual but also to those around them. It also examines how individuals cope (or fail to cope) with emotional scars and the long-term effects of unaddressed psychological issues, such as anger, resentment, and a sense of identity loss.
The Intricacies of Familial Relationships and the Burden of Unspoken Secrets
The dynamics of familial relationships play a crucial role in It’s One of Us, with much of the tension arising from the long-buried secrets that resurface and threaten to unravel the family unit. Olivia’s past with Perry, Park’s twin brother, is a central plot element that ties together many of the story’s themes of betrayal, guilt, and unspoken truths.
The return of Perry to Nashville reignites old tensions and forces Olivia to confront her past mistakes, particularly her one-night affair with him. The secret of this affair, hidden for years, weighs heavily on Olivia’s conscience and causes further strain in her already fragile marriage.
Meanwhile, Park’s relationship with Perry is marked by rivalry, guilt, and the unspoken trauma of their shared history. The psychological toll of these unaddressed familial issues underscores the complexity of family dynamics, where love, betrayal, and unresolved conflicts continuously shape the actions and behaviors of the characters.
The novel powerfully illustrates how familial bonds, often built on silence and avoidance of difficult truths, can become fragile and ultimately destructive when secrets are exposed.
