Summary
Jessica wakes up to a stormy morning in Hell’s Kitchen, feeling disoriented after a night of drinking.
The chaos of the world around her weighs heavily on her mind, and she decides to feed her neighbor Julius’s cat, Speckles. As she enters Julius’s apartment, the storm worsens, and the cat panics, escaping through the door into the hallway. Jessica chases Speckles, who disappears into an unfamiliar part of the building, before eventually finding the cat on a precarious ledge between two buildings. She manages to coax the cat back, only to encounter a strange little girl dressed in a metallic fur-trimmed coat. The girl vanishes before Jessica can approach her, leaving her unsettled and confused.
Later, Jessica is visited by Amber Randall, a client from Alias Investigations.
Amber has concerns about her twin children, Lark and Fox, who have returned from a trip to their father’s estate in Essex with strange behavioral changes. Amber believes that her children have been replaced by impostors and asks Jessica to investigate.
Although Jessica is skeptical of Amber’s suspicions, she agrees to take the case for a generous retainer.
Jessica meets with Amber at a club called The Finch, where Amber provides more details about the twins’ unusual behavior. Jessica tails Lark and her friends one evening but observes nothing out of the ordinary. However, she does notice that Lark’s skin appears unnaturally flawless, adding to Amber’s suspicions.
Amber insists that Jessica investigate Fox next, who is attending a birthday party. She provides Jessica with a reservation to observe Fox’s behavior at the event.
Throughout this time, Jessica grapples with her own personal insecurities, including her appearance, and hires a stylist to help her feel more confident. During her walk back to her apartment, she spots the strange girl again.
When Jessica tries to speak with her, the girl vanishes once more, deepening Jessica’s sense of unease.
As Jessica continues her investigation, she follows Fox to the party, where she observes nothing unusual, but she does notice his odd, almost otherworldly presence.
Later, Jessica returns to Amber to debrief, but her feelings of uncertainty only grow as she becomes more immersed in the case. Amber is adamant that Jessica continue her investigation, urging her to keep an eye on Fox.
Jessica’s investigation leads her to suspect that something deeper is at play. She struggles to reconcile Amber’s paranoid fears with her own observations, as she navigates a world that seems increasingly disconnected and surreal.
The strange occurrences involving the children, the mysterious girl, and the unsettling atmosphere around her begin to weigh heavily on Jessica, making her question whether she’s simply dealing with an overzealous client or something far darker.
One evening, while dealing with her own personal anxieties, Jessica is once again confronted by the strange girl, whose presence is both unnerving and intriguing. She feels a growing need to understand who this child is and what role she plays in the mysterious events surrounding her investigation.
However, when Jessica attempts to confront the girl, she disappears into thin air, leaving Jessica with more questions than answers.
As Jessica digs deeper into the case, she uncovers unsettling details about the twins’ time in Essex, including their involvement with a mysterious figure named Belle.

The mystery surrounding the children, combined with Jessica’s complicated emotional state, leads her to confront her fears and uncertainties about the world around her.
Jessica’s investigation takes a new turn when she learns about an app called Miranda, which uses quantum physics and AI to alter human appearances. The app, initially developed to create idealized versions of people, has been used in experiments to eliminate imperfections by absorbing defects. The process has resulted in disastrous consequences, with some of the subjects dying or suffering from extreme transformations.
As Jessica continues to investigate, she uncovers a dark plot involving young girls being used as vessels to absorb imperfections, orchestrated by a mysterious antagonist named Polly, who hides behind the Miranda persona. Polly plans to launch the app globally, creating a world where everyone is perfect.
Jessica and her team manage to stop the public launch event in Central Park, but not before many people unknowingly use the app, resulting in bizarre and unnatural transformations.
Polly is arrested, but her plan has already set in motion a global shift that threatens to change humanity forever.
As the story progresses, Jessica struggles with her own personal demons, including her trauma from the past and her uncertain relationship with Luke. The revelation that she is pregnant further complicates her already tumultuous life.
The pregnancy brings both fear and hope, as Jessica faces the future with a mix of anticipation and trepidation.
In the end, Jessica reflects on the moral implications of the app, the people she’s lost, and the choices she has made. The story concludes with Jessica taking steps toward healing, preparing for her future as a mother while still grappling with the fallout from the dark conspiracy she uncovered.
Her journey toward self-restoration is just beginning, as she strives to find peace in a world forever changed by the events she’s witnessed.

Characters
Jessica
Jessica is a complex and multifaceted protagonist, struggling to navigate both her personal and professional challenges.
As an investigator, she is hired to uncover the truth behind the strange behaviors of twins Lark and Fox, yet she is also grappling with her own unresolved emotional turmoil. Jessica’s experience is colored by a deep sense of isolation, exacerbated by her past as a former superhero.
This trauma influences her relationships, particularly with Luke, where emotional distance clouds their connection despite their bond. Throughout the story, Jessica faces numerous disturbing events, including the unsettling appearance of a strange child and the disorienting effects of the Miranda app.
As her investigation into the twins and the supernatural occurrences deepens, she is forced to confront her own fears and insecurities. Jessica’s journey is one of self-discovery, with her pregnancy serving as a pivotal moment that brings both hope and terror, adding complexity to her already chaotic life.
Despite her personal struggles, she demonstrates resilience, attempting to navigate the dark forces at play while also grappling with the weight of her past. Her internal conflict and her growing understanding of herself are central to the narrative, offering a layered portrayal of a woman caught between her traumatic history and the possibility of a new future.
Lark
Lark is one of the mysterious twins at the center of Jessica’s investigation.
On the surface, she appears to be a typical teenager, yet there is an unsettling quality to her behavior that makes her seem out of place.
Lark’s unnaturally flawless skin and aloof demeanor contribute to the suspicion that she may not be the same person she was before her trip to Essex.
As the story unfolds, it becomes clear that Lark has undergone some form of transformation, possibly linked to the app Miranda, which aims to perfect human beings by altering their physical appearance.
Lark’s behavior is a key piece in the puzzle Jessica is trying to solve, and her emotional detachment hints at the possibility of something darker and more sinister at play.
While she remains enigmatic and distant, Lark’s connection to Fox and the broader conspiracy of the app’s creators makes her an integral part of the unfolding mystery. Her transformation mirrors the disturbing consequences of the app’s power, making her a symbol of the story’s exploration of identity, control, and the cost of perfection.
Fox
Fox, like his twin sister Lark, undergoes a disturbing transformation after returning from his summer trip to Essex.
His strange, almost otherworldly presence adds to the growing suspicion that something unnatural is at play. Jessica becomes increasingly fixated on him, particularly after overhearing comments about his sudden changes and witnessing unsettling events involving his body.
Fox’s role in the story becomes more significant as the investigation reveals his involvement with the Miranda app and his connection to the larger scheme of using young people as vessels for perfection. Fox’s behavior, like Lark’s, is marked by an eerie detachment, which raises questions about the true nature of the twins’ changes.
Throughout the investigation, Fox is depicted as both a victim and a participant in the dark forces controlling his life. His connection to the app’s creators and the manipulation of his body serves as a poignant commentary on the dangers of trying to achieve physical and psychological perfection at any cost.
Fox’s character is integral to the story’s exploration of the moral implications of altering one’s identity and the irreversible consequences that such actions bring.
Luke
Luke plays a significant role in Jessica’s life, though their relationship is strained and complicated. As a character, Luke represents a foil to Jessica’s internal struggles.
He shares a deep connection with Jessica but is emotionally distant, which mirrors Jessica’s own feelings of isolation. His reluctance toward fatherhood and his cynical outlook on the world create a sense of detachment between them, even though they share a bond formed by shared history and mutual respect. Luke’s perspective on life adds a layer of tension to Jessica’s journey, particularly as she grapples with the revelation of her pregnancy.
His attitude toward the situation reflects his own fears and uncertainties, further complicating the dynamics between them. Despite their connection, Jessica’s emotional distance from Luke underscores her broader sense of disconnection from those around her, as she struggles to find stability amidst the chaos of her investigation and the supernatural events she encounters. Luke’s character highlights the theme of complicated relationships and emotional turmoil, serving as a grounding presence in Jessica’s otherwise tumultuous world.
Malcolm
Malcolm serves as Jessica’s assistant, but his role extends beyond that of a mere support character.
He is resourceful and becomes an invaluable ally in Jessica’s investigation. His involvement in the case is crucial, as he helps Jessica uncover critical information about the twins and their connection to the mysterious app Miranda. Malcolm’s character is marked by a sense of loyalty and determination, as he takes on a proactive role in tracking down information and aiding Jessica in her pursuit of the truth.
His actions, such as gathering intelligence on the twins and their connection to Belle in Essex, show that he is not merely an assistant but an active participant in solving the puzzle that unfolds throughout the story.
Although Malcolm is a secondary character, his presence is felt throughout the narrative, providing Jessica with a sense of support and direction as she navigates the increasingly bizarre events surrounding her. His relationship with Jessica adds depth to the story, as their professional partnership is tested by the growing tension and danger surrounding the investigation.
Polly
Polly is the main antagonist in Breaking the Dark, orchestrating a nefarious plan to manipulate human beings and create a utopia by altering their physical appearances through the app Miranda.
Her character is marked by a chilling level of control and manipulation, as she hides behind the persona of Miranda to push forward her dangerous agenda. Polly’s ultimate goal is to perfect humanity by absorbing imperfections, using young girls as vessels to rid them of their flaws.
This dark, almost inhuman ambition makes her a formidable and terrifying antagonist. Her manipulative nature is evident in the way she uses others, particularly the twins, to further her plans, and her ability to stay hidden behind the app’s façade adds a layer of deception to her character. Polly’s actions drive the central conflict of the story, as Jessica and her team race against time to stop her.
Her character embodies the dangers of unchecked ambition and the ethical dilemmas that arise from the pursuit of perfection.
Themes
Identity and Transformation
Throughout Breaking the Dark, the theme of identity and transformation plays a significant role as Jessica grapples with both her physical and psychological changes.
At the center of this exploration is the concept of the Miranda app, a tool designed to alter and perfect human beings by modifying their appearance. This app symbolizes society’s obsession with flawlessness and its desire to reshape individuals according to idealized standards, often at the cost of their authenticity. As Jessica investigates the app and its effects, she confronts her own internal conflict about the transformation of self. The external changes she experiences, like the unsettling perfection of her skin after her escape from Debra’s house, mirror her internal struggle to reconcile her past and present identities.
Her feelings of disconnection from her own body and mind reflect a broader commentary on how personal identity can be manipulated, whether through external pressures or the darker machinations of technology. Jessica’s pregnancy further complicates this transformation, forcing her to confront the possibility of motherhood while simultaneously navigating the unsettling implications of the changes happening around her.
This theme underscores the fragility of identity and how it can be molded, lost, or distorted through external forces and personal trauma.
Technology and Control
The theme of technology as a tool of control is another central element in the story, especially through the manipulation of the app, Miranda.
The app’s ability to alter physical appearance by using quantum physics and artificial intelligence highlights the potential dangers of technological advancements when wielded without ethical considerations. The app’s creators, who initially sought to perfect human beings, soon use it on vulnerable young people, turning it into a tool of oppression rather than empowerment.
The experimentation with young subjects and the tragic outcomes that follow illustrate the dark side of innovation—how technological progress, while seemingly promising, can also lead to exploitation and harm. Furthermore, Polly’s use of Miranda as a vehicle to create a utopia based on perfection represents the authoritarian use of technology to control not just individuals, but entire populations.
The story presents technology as a force that can transcend the personal and become an instrument of mass manipulation, where the line between choice and coercion becomes dangerously blurred. As Jessica unravels the conspiracy behind Miranda, she uncovers the moral and societal implications of such advancements, raising questions about who gets to control technology and for what purposes.
Trauma and Healing
Jessica’s journey is deeply intertwined with the theme of trauma and the slow, often painful process of healing.
From the onset, Jessica struggles with unresolved issues from her past, particularly her former life as a superhero, which left her with emotional scars that she has yet to address. Her encounters with the mysterious girl and the bizarre occurrences around her life serve as constant reminders of her unresolved pain and the trauma she carries. The tension between her past and present is further complicated by the revelations about her pregnancy, which forces Jessica to confront her fears and hopes about the future. The people around her, like Luke, reflect her struggles with intimacy and connection, often serving as emotional mirrors that force her to look at her own vulnerabilities.
In this context, healing becomes a slow and nonlinear process.
The narrative illustrates that healing is not a clean break from trauma but rather a journey that involves painful self-reflection, confronting fears, and seeking support from others. Despite the dark forces at play in Jessica’s life, her eventual steps toward understanding herself and preparing for motherhood suggest that healing, while difficult, is possible even in the face of overwhelming odds.
Moral Ambiguity and Ethical Dilemmas
Breaking the Dark presents a world where moral boundaries are often unclear, and characters must navigate complex ethical dilemmas. Jessica’s investigation into the strange behaviors of Lark and Fox leads her down a path where the line between right and wrong becomes increasingly blurred.
Her professional life as a private investigator often puts her at odds with her own moral compass, particularly as she becomes more entangled in the larger conspiracy surrounding Miranda. The app, which initially seems like a tool to improve lives, is soon revealed to be a dangerous and exploitative mechanism that alters people’s appearances for a price.
As Jessica unravels the conspiracy, she is forced to grapple with the consequences of her actions, questioning whether the pursuit of truth justifies the methods she employs.
Additionally, the characters around her, such as Luke and Amber, embody varying shades of moral complexity, with their own motives and actions creating a web of conflicting interests. This theme explores how individuals can justify their actions even when they lead to harm, and how, in the pursuit of a greater good, they may lose sight of their own ethical boundaries.
The Supernatural and the Unknown
From the beginning of the story, Jessica’s experiences are marked by an increasing sense of unease, as strange and supernatural occurrences seem to follow her.
The mysterious girl she encounters and the feeling of being in a world that is not quite right suggest that there are forces at play beyond Jessica’s understanding. This supernatural theme plays on the idea of a reality that is warped by unknown forces, leaving Jessica—and the reader—constantly questioning what is real.
As Jessica’s investigation deepens, she finds herself facing not just a conspiracy involving technology and manipulation but also an inexplicable presence that seems to haunt her. The supernatural elements in the story blur the lines between the rational and the irrational, creating an atmosphere of uncertainty that permeates every aspect of Jessica’s life. Whether the strange girl is a figment of Jessica’s imagination or a manifestation of something more sinister remains a key mystery throughout the narrative, emphasizing the idea that there are unseen forces that shape our reality in ways we may never fully understand.
The presence of the supernatural underscores the fragility of human perception and the unsettling feeling of being unable to trust one’s own senses in a world that feels increasingly unfamiliar.
