Plot Summary
Blood on the Creek
In Tuscaloosa, Alabama, the body of Annabelle Chapman, the mayor's wife, is found by Hurricane Creek, her skull brutally crushed. The town reels in shock, unused to such violence. Fourteen-year-old Mason Hill, a boy with autism, is discovered at the scene, covered in blood, rocking and unresponsive. His mother, Genevieve, claims he tried to save Annabelle, but suspicion falls heavily on Mason. The police, desperate for answers and pressured by a terrified community, begin their investigation, setting off a chain of events that will unravel the facades of family, motherhood, and the meaning of innocence.
Autism and Accusation
Casey Walker, a pediatric psychologist and single mother to a daughter with autism, is recruited by Detective Layne to help communicate with Mason. The police hope Casey can break through Mason's silence and uncover what happened at the creek. As Casey navigates the tense atmosphere—Genevieve's fierce protectiveness, the town's fear, and the police's urgency—she is forced to confront her own biases and the complexities of working with children who cannot easily speak for themselves. The line between advocacy and investigation blurs as Casey becomes entangled in the case.
Mothers Under Pressure
Genevieve's world is upended. She is besieged by suspicion, the media, and her own terror that the real killer is still at large. Her protectiveness over Mason becomes obsessive, and her grip on reality begins to fray. Meanwhile, Casey juggles her professional responsibilities with her personal anxieties, haunted by memories of her own mother's advice and the ever-present fear for her daughter's safety. Both women are isolated by their roles as mothers to children who are different, and both are judged—by themselves and others—for every choice they make.
The Lies We Tell
As Detective Layne and Casey probe deeper, inconsistencies in Genevieve's account emerge. She admits to lying about the details of the day at the creek, fearing that the truth would condemn Mason. The police and Casey realize that Genevieve's need to control the narrative is as much about protecting her image as her son. The investigation exposes the ways in which people—especially mothers—lie to protect, to survive, and to maintain the illusion of control in a world that judges them harshly.
Trauma and Routine
Mason's life is built on routine, and the disruption of the murder and subsequent investigation sends him into a spiral. Genevieve's attempts to maintain normalcy for Mason become increasingly desperate, while her own trauma manifests in paranoia and sleeplessness. Casey, too, is stretched thin, balancing her daughter's needs with the demands of the case. The emotional toll of trauma—on children and adults alike—becomes a central theme, highlighting the fragility of the structures people build to keep chaos at bay.
Testing the Truth
Casey reviews Mason's extensive psychological records and notices troubling patterns: his test scores are suspiciously consistent, and there are hints of psychiatric issues and possible abuse. She suspects that Mason's disabilities may have been exaggerated or even fabricated. When she finally tests Mason herself, she discovers that he has been trained to fail the tests in a specific way, raising disturbing questions about who is shaping his identity and why.
The Mask of Disability
The evidence mounts that Mason's intellectual disability and aspects of his autism have been deliberately constructed—possibly by Genevieve, possibly with the involvement of her late husband, John. Casey and Detective Layne realize that Mason's entire life has been orchestrated to fit a narrative of helplessness and dependence. The implications are chilling: Mason is both a victim and a pawn, his true self buried beneath layers of conditioning and medication. This reveals the central plot device of psychological manipulation and conditioning.
Family Secrets Unveiled
Casey seeks out Savannah, Genevieve's estranged daughter, whose testimony reveals a history of emotional neglect, control, and possible violence within the Hill family. Savannah describes how Genevieve's obsession with Mason's illness began after Savannah quit beauty pageants and was emotionally abandoned by her mother. The family's secrets—mental illness, manipulation, and the mysterious death of John Hill—come to light, painting a portrait of a household built on denial and performance.
Bruises and Betrayal
After Casey notices bruises on Mason's arms, a mandated report leads to Mason being removed from Genevieve's care and placed in foster care. Genevieve, enraged and desperate, retaliates by filing a false abuse report against Casey, resulting in Casey's own daughter being temporarily taken away. The system's blunt instruments of protection and punishment are wielded with devastating consequences, and both women are pushed to the brink by the loss of their children.
The Daughter's Testimony
Savannah's psychiatric history is revealed, casting doubt on her reliability. Yet her insights into Genevieve's character and the family's dynamics are invaluable. She suggests that Genevieve thrives on the attention and sympathy generated by her children's suffering, and that Mason's regression was not natural but induced. Savannah's own survival has depended on learning to play her mother's games, and her perspective becomes crucial as the investigation reaches its climax.
The Monster's Shadow
Genevieve is blackmailed by a mysterious figure who claims to have evidence of her past crimes—including the abuse of Mason and the possible murder of her husband. As she scrambles to gather cash for the blackmailer, the lines between victim and perpetrator blur. Meanwhile, Mason, in foster care, begins to thrive, revealing abilities and independence previously unseen. The true extent of Genevieve's manipulation and the collateral damage she has caused become increasingly clear. Simon looms as a phantom threat.
Foster Home Awakening
Away from his mother's control, Mason begins to communicate more freely, using assistive technology to express himself. He asks Casey for help, signaling his awareness of his own victimization. The foster home, overseen by Blanche, provides a stark contrast to his previous life, and Casey realizes that Mason's disabilities were, in large part, imposed upon him. The system that failed to protect him is now his only hope for rescue.
Blackmail and Confession
As the blackmailer presses for payment, Genevieve's carefully constructed life collapses. She confesses on television that Mason was involved in Annabelle's death, but frames it as an act of mimicry—he only did what he saw someone else do. The confession is both a betrayal and a final act of control, ensuring that Mason, not she, will bear the blame. Meanwhile, Casey races to gather evidence that will exonerate Mason and expose Genevieve's crimes. This demonstrates public performance and media manipulation.
The Trap in the Woods
Genevieve arranges to meet the blackmailer in a remote, wooded area, bringing the demanded cash and a gun. Casey, having tracked Genevieve's movements, follows her into the woods, determined to catch her in the act and save Mason. The blackmailer, revealed to be Savannah's accomplice, is shot by Genevieve, but Casey intervenes before Genevieve can kill again. The confrontation is violent and chaotic, but ultimately, Genevieve is subdued.
The Final Confrontation
With the police on their way, Casey holds Genevieve at gunpoint, demanding answers. Genevieve confesses to orchestrating Mason's disabilities and manipulating everyone around her, insisting she did it to make him "extraordinary." Her lack of remorse is chilling, and Casey realizes that true evil often hides behind the mask of maternal devotion. As sirens approach, Genevieve attempts to escape, but Casey stops her, ensuring that she will finally face justice.
The Daughter's Revenge
In a parallel narrative, Savannah and her accomplice, Brett, are revealed as the architects of the blackmail scheme. Savannah, shaped by years of her mother's cruelty, orchestrates Brett's overdose to tie up loose ends and secure her own escape. She leaves behind a trail of forged evidence and a letter framing Brett as a junkie, ensuring that she will never be implicated. Savannah's actions are both a reckoning and a perpetuation of the cycle of abuse and revenge.
The Truth Surfaces
With Genevieve arrested and Mason safe in foster care, the community begins to reckon with the truth. Casey, though battered by the ordeal, finds solace in her daughter's return and the knowledge that she helped save an innocent child. The story ends with Mason, now free from his mother's control, beginning to reclaim his voice and agency. The scars of trauma remain, but the possibility of healing—however imperfect—offers a glimmer of hope.
Analysis
A chilling exploration of maternal power, societal judgment, and the construction of identityUnder Her Care is a psychological thriller that interrogates the boundaries between protection and control, love and harm. Lucinda Berry uses the framework of a murder investigation to peel back the layers of family dysfunction, exposing the ways in which trauma, ambition, and the hunger for validation can warp even the most sacred bonds. The novel's greatest strength lies in its refusal to offer easy answers: every character is both victim and perpetrator, shaped by forces beyond their control and choices they cannot undo. The story is a critique of the systems—legal, medical, social—that fail the most vulnerable, and a meditation on the power of narrative to both heal and destroy. Casey Walker's journey as an empathetic psychologist and Genevieve Hill's unraveling as a controlling mother demonstrate the complex interplay of psychological manipulation, unreliable narration, and the cycle of abuse. Mason Hill's liberation through assistive technology and Savannah Hill's revenge plot illustrate how victims can reclaim agency, even as they perpetuate harm. Ultimately, the book asks: Who gets to speak, and who is believed? In a world where appearances are everything, the truth is often the first casualty. The lesson is clear: real care requires seeing beyond the masks we wear, and justice demands listening to the voices we are most inclined to ignore.

Characters
Casey Walker
Casey is a pediatric psychologist specializing in autism, and a single mother to Harper, her own daughter with autism. Her expertise and compassion draw her into the investigation, but her involvement quickly becomes personal. Casey is driven by a fierce sense of justice and a deep empathy for children who cannot speak for themselves. She struggles with guilt, self-doubt, and the fear of failing those she loves. Over the course of the story, Casey evolves from a cautious outsider to a determined advocate, risking everything to uncover the truth and protect Mason. Her journey is one of moral courage, resilience, and the painful recognition of the limits of her power.
Genevieve Hill
Genevieve is the mother of Mason and Savannah, a former beauty queen, and a local celebrity known for her advocacy in the autism community. Beneath her polished exterior lies a woman consumed by the need for attention, control, and validation. Genevieve's love for Mason is twisted by her desire to be seen as a martyr and a hero. She manipulates, lies, and ultimately harms those closest to her, including her own children. Her psychological profile is complex: she is both a victim of societal expectations and a perpetrator of profound harm. Genevieve's unraveling is both tragic and terrifying, revealing the dark side of maternal devotion.
Mason Hill
Mason is a fourteen-year-old boy with autism, or so everyone believes. In reality, much of his disability has been constructed by his mother through conditioning, medication, and emotional manipulation. Mason is gentle, sensitive, and deeply traumatized. His inability to communicate masks a keen awareness of his own suffering. When finally given the tools and freedom to express himself, Mason reveals both the depth of his pain and his capacity for resilience. His journey is one of liberation from the roles imposed upon him, and his plea for help is the emotional heart of the story.
Savannah Hill
Savannah is Genevieve's older child, emotionally abandoned by her mother after quitting beauty pageants. She has a history of psychiatric hospitalizations, some of which were induced or exaggerated by Genevieve. Savannah is intelligent, resourceful, and deeply wounded. Her alliance with Brett and her orchestration of the blackmail plot are acts of both revenge and self-preservation. Savannah's actions blur the line between victim and perpetrator, and her final act—murdering Brett to secure her own escape—cements her as a complex antihero shaped by a lifetime of betrayal.
Detective Layne
Detective Layne is the lead investigator on Annabelle's murder. He is a product of his environment: practical, sometimes insensitive, and under immense pressure to deliver results. Layne's approach is methodical but often blinkered by his assumptions and the community's demands. He values Casey's expertise but is ultimately more concerned with closure than truth. Layne represents the limitations of institutional justice and the dangers of rushing to judgment.
Brett
Brett is Savannah's partner in the blackmail scheme, a former psychiatric patient with a history of addiction. He is loyal to Savannah but ultimately expendable in her eyes. Brett's involvement in the plot is motivated by love, desperation, and a desire for escape. His fate—overdosed and framed by Savannah—underscores the story's themes of manipulation, betrayal, and the collateral damage of family dysfunction.
Harper Walker
Harper is Casey's nine-year-old daughter with autism. She is nonverbal but communicates through assistive technology. Harper's presence grounds Casey and serves as a reminder of the stakes involved in the case. Her temporary removal from Casey's care highlights the vulnerability of children with disabilities and the failures of the systems meant to protect them.
John Hill
John is Genevieve's late husband, whose mysterious death and discovery of Genevieve's abuse set the stage for the family's unraveling. Though dead, his presence looms large in the narrative, both as a victim and as someone who failed to protect his children. John's legacy is one of missed opportunities and the devastating consequences of silence.
Simon (the Monster)
Simon is the supposed attacker at the creek, a figure conjured by Genevieve and Savannah's schemes. He represents the externalization of guilt and the projection of evil onto an imagined other. Simon's existence is a narrative device used to deflect blame and maintain the illusion of innocence, functioning as a red herring.
Blanche
Blanche is the house mother at Mason's foster home. Her care and structure provide Mason with the stability and safety he has never known. Blanche's role, though secondary, is crucial in demonstrating the possibility of recovery and the importance of genuine compassion.
Plot Devices
Unreliable Narration and Shifting Perspectives
The novel employs alternating first-person perspectives—primarily Casey and Genevieve, with interludes from Savannah and Mason's internal monologue. This structure creates ambiguity, as each character's account is colored by their own motives, traumas, and self-deceptions. The reader is forced to piece together the truth from conflicting narratives, mirroring the investigative process and highlighting the subjectivity of memory and perception.
Psychological Manipulation and Conditioning
A central device is the deliberate construction of Mason's disabilities through behavioral conditioning, medication, and emotional abuse. This plot element serves as both a metaphor for the ways in which society imposes roles on the vulnerable and a literal mechanism of control. The revelation that Mason's impairments are, in part, manufactured is a devastating twist that reframes the entire narrative.
Red Herrings and Misdirection
The investigation is littered with red herrings: the possibility of an unknown killer, the focus on Mason as the prime suspect, and the introduction of Simon as the "Monster." These devices keep the reader—and the characters—off balance, delaying the revelation of Genevieve's guilt and Savannah's machinations.
The Cycle of Abuse and Revenge
The story explores how trauma begets trauma, with Savannah's actions mirroring and amplifying her mother's cruelty. The blackmail plot, Brett's murder, and the framing of others are all extensions of the harm inflicted by Genevieve, demonstrating the inescapable reach of abuse.
Assistive Technology as Liberation
The use of assistive technology (TouchChat) is a pivotal device, enabling Mason to finally express his need for help. This moment is both a narrative turning point and a symbolic act of reclaiming voice and autonomy, challenging the notion that silence equals incapacity.
Public Performance and Media Manipulation
Genevieve's mastery of public performance—her televised confession, her social media presence, and her manipulation of sympathy—serves as both a shield and a weapon. The contrast between her public persona and private actions underscores the theme of duplicity and the dangers of believing appearances.
