Summary
Fifteen years ago, Rhett Cole and Lainey Taylor were young, inseparable, and deeply in love—until a single tragic event changed the course of their lives forever.
Lainey’s younger sister, Penelope, died in a boating accident while Rhett was driving the boat.
Her death shattered everything: Lainey’s family blamed Rhett, Rhett blamed himself, and Lainey was left torn between her love for Rhett and the grief of losing her sister.
The incident created a chasm that neither could cross, and Lainey fled Los Angeles to escape the pain, trying to rebuild her life from afar.
Now in the present, fate orchestrates their reunion at a bachelor/bachelorette party for mutual friends.
The Spade Hotel, luxurious and iconic, becomes the setting for old wounds to resurface and long-buried emotions to be reawakened.
Rhett, once a lively and driven young man, is now haunted and withdrawn, emotionally locked inside the day Penelope died.
Lainey, though successful and independent, is quietly battling the ache of unresolved loss and unanswered questions.
As the story moves between present-day interactions and flashbacks to their teenage years, a fuller picture of their relationship emerges.
Readers witness the youthful intensity of Rhett and Lainey’s first love: secret kisses, shared dreams, and the promise of forever.
These memories sharply contrast the bitterness and emotional volatility of their present, where neither truly understands what happened on the boat that day.
Rhett has never told his version of events, and Lainey never dared to ask.
Their reunion is tense and emotional.
Rhett’s unresolved guilt bleeds into every conversation, while Lainey struggles to reconcile the man in front of her with the boy she loved and the person she thought caused her sister’s death.
Through emotionally charged encounters, Rhett finally begins to reveal the truth he’s carried alone for years.
He recounts the day of the accident, the erratic behavior Penelope exhibited, and how helpless he felt when she jumped.
His version contradicts the assumptions Lainey’s family held onto, painting a more complex and tragic picture of the accident.
Rhett also confesses to hiring someone to find Lainey after years of separation—a choice born not of malice, but desperation.
His obsession with reliving the accident and longing for closure shows how he’s been psychologically stuck in that day.
Lainey, meanwhile, begins to see how much she didn’t know, including how hard Rhett tried to save Penelope and how devastated he’s been since.
As their emotional connection reignites, so does the physical attraction that once bonded them.
But their reunion isn’t just about desire—it’s about trust, truth, and healing.
Lainey returns to familiar places, each layered with painful memories, and finds Rhett there, often lost in reflection.
Slowly, they begin to rewrite those memories, reclaiming moments once drowned in grief.
Lainey’s journey back to her family becomes pivotal.
She confronts her mother, who surprisingly begins to soften, finally listening to what really happened.
Through honest conversations and shared sorrow, Lainey’s family begins to release the blame they’ve harbored for years.
By the end of the book, Rhett and Lainey are not just trying to recover what they lost—they’re creating something new out of the wreckage of their past.
The story builds toward a powerful emotional and romantic resolution, promising a future that neither thought possible when they first locked eyes across the party that brought them back together.
The One is ultimately a story of survival—not just of grief, but of love.
It’s about the strength it takes to confront your past, the courage to forgive, and the rare, beautiful chance of rediscovering “the one” when the heart is finally ready.

Characters
Rhett Cole
Rhett Cole is a deeply tortured and emotionally complex man whose life is defined by a singular tragic event—Penelope’s death. His character is introduced as a successful, wealthy, yet emotionally scarred individual who has never recovered from the trauma of losing his girlfriend’s sister under his watch.
What sets Rhett apart is his profound loyalty and obsessive love for Lainey, which has remained untouched by time or distance. The guilt he carries is all-consuming; it drives him into cycles of self-punishment and isolation.
His every action, from hiring someone to follow Lainey to reliving the day of the accident daily in his mind, is rooted in a desperate need for closure and forgiveness. Rhett’s internal conflict is magnified by his silence—fifteen years of not telling his side of the story about what really happened on the boat—showcasing his self-blame and the emotional paralysis caused by unresolved trauma.
When he finally opens up, it reveals a man who was never at peace, who loved fiercely, and who was unfairly vilified by grief-stricken others. Rhett’s journey is ultimately one of redemption: he fights not just for Lainey’s love, but to reclaim his sense of self-worth.
The raw vulnerability and desperate yearning he exhibits are heart-wrenching. His emotional awakening becomes the catalyst for the story’s healing arc.
Lainey Taylor
Lainey is portrayed as a woman whose life has been bifurcated by tragedy—before Penelope’s death and after. Her character walks the fine line between strength and emotional fragility.
She initially appears guarded and resentful, understandably unable to forgive Rhett or herself for what happened. Her grief is compounded by the forced separation from Rhett, her first and truest love, making her heartache dual-layered.
Yet, beneath her anger lies a quiet longing—a yearning for truth, for reconciliation, and for the comfort of a love that never truly left her. Lainey’s journey is as much about self-discovery as it is about confronting the ghosts of her past.
She had built a life in New York, far from her emotional wreckage, yet never moved on emotionally. Her return to LA signifies a subconscious desire to face the pain she buried.
As Rhett begins to open up, Lainey undergoes a transformation—from guarded and accusatory to open-hearted and courageous. She listens with a newfound empathy, confronts her parents’ biases, and ultimately chooses to rewrite her story with Rhett.
Lainey emerges as a deeply empathetic and evolved woman who reclaims her agency in both love and loss.
Penelope Taylor
Though deceased, Penelope’s presence looms large over the narrative, shaping every major decision and emotional reaction of the living characters. She is remembered as vibrant but impulsive, emotional, and perhaps self-destructive.
Her tragic death is initially cloaked in ambiguity, casting her as a victim of negligence. However, Rhett’s revelations add nuance: Penelope was erratic, under the influence, and her behavior on the boat was volatile.
This complicates her memory—was she a victim, or someone wrestling with her own emotional demons? Her jealousy toward Lainey and hints of rivalry suggest deeper psychological conflicts.
Penelope’s legacy becomes a battleground for guilt, blame, and truth. It is only when her actions are fully understood that healing can begin.
Her character functions more as a symbolic force than a fully fleshed-out figure, but her impact is profound. She represents unresolved grief, the distortion of memory, and the perilous consequences of emotional instability left unchecked.
Lainey’s Mother
Lainey’s mother undergoes a subtle but crucial evolution in the story. Initially painted as someone blinded by grief and anger, she directs her sorrow into blaming Rhett entirely, thus cutting him out of their lives.
Her emotional rigidity creates a chasm not only between Rhett and the family but also between Lainey and her past. However, in the later chapters, she becomes a symbol of redemption and maternal love.
When confronted with the truth and finally allowed to see the video of Penelope’s behavior, she does something remarkable—she listens. Her eventual blessing of Lainey’s relationship with Rhett marks one of the story’s emotional turning points.
This moment of acceptance signifies generational healing and the surrender of long-held pain. Her transformation, though brief on the page, is deeply impactful and allows the narrative to close its emotional arcs with grace and forgiveness.
Lainey’s Father
Unlike Lainey’s mother, her father is a more rigid and unforgiving figure throughout the narrative. His decision to permanently sever ties with Rhett after Penelope’s funeral, and his continued resistance to reopening that wound, underscores the depth of his grief—but also his inability to process it in a healthy way.
He becomes a static symbol of unresolved pain and emotional denial. Unlike Lainey’s mother, he doesn’t appear to offer closure or approval by the end of the novel, leaving his character shrouded in unresolved bitterness.
This makes him a counterpoint to Lainey and Rhett’s arcs of forgiveness. His inability to move on acts as a cautionary echo of what happens when grief calcifies into resentment.
His presence, even in absence, serves to remind the reader of the devastating collateral damage of tragedy.
Themes
The Weight of Guilt and the Path to Redemption
The One is the exploration of guilt—both earned and unearned—and how it shapes lives, decisions, and identities. Rhett carries the burden of Penelope’s death for over a decade and a half, not merely because others blamed him, but because he internalized that blame to a destructive degree.
His guilt defines his emotional state, corrodes his sense of self-worth, and becomes the root of his obsessive behaviors, including having Lainey followed years later. The tragedy of the boating accident functions as the axis around which his entire life spins, showing how a singular traumatic event can calcify in the memory and manifest in debilitating patterns.
This theme also extends to Lainey, whose guilt stems not from actions, but from omission—what she did not know, what she never asked, and what she avoided confronting for years. Her loyalty to her sister’s memory creates a moral conflict that holds her hostage emotionally.
Redemption, then, becomes a complex, incremental process in the novel. It is not easily granted but rather painstakingly earned through vulnerability, confession, and the willingness to be truly seen.
Rhett’s redemption begins only when he tells the full truth, not to the world, but to the person whose understanding matters most. The novel suggests that healing from guilt requires confronting not just others’ perceptions but one’s own refusal to forgive oneself.
The path to redemption lies in truth-telling, mutual compassion, and deep emotional risk.
The Persistence of First Love
Lainey and Rhett’s romance underscores the enduring, and at times haunting, nature of first love. The story paints their teenage connection as something so deeply formative that it cannot be erased by time, distance, or even tragedy.
Even after fifteen years apart, the emotional undercurrents between them remain electrified, revealing how first love imprints itself on the psyche and heart in lasting ways. The novel doesn’t romanticize this fact as purely sweet or nostalgic; instead, it acknowledges the intensity and complications of a love formed during a highly emotional developmental stage.
Rhett’s yearning borders on obsession, while Lainey’s continued emotional tether to him complicates her present-day choices. Their story reflects the notion that first love often serves as a reference point for all subsequent emotional connections, for better or worse.
The power of their reunion is less about rekindling a past flame and more about acknowledging how that love, however painful, shaped who they became. Even when the characters attempt to move on, they find themselves emotionally anchored to that initial bond.
The narrative presents this enduring love not as a fantasy ideal but as a deeply emotional truth that demands reckoning. Only by understanding and forgiving the past are Rhett and Lainey able to fully appreciate what their love could become in adulthood.
Their love becomes mature, honest, and stripped of illusion. The story treats first love as both a beautiful foundation and a potential emotional trap, one that must be navigated carefully to lead to lasting fulfillment.
The Complexity of Forgiveness
Forgiveness in The One is not offered as a simple or automatic virtue. Instead, it emerges as an emotional and moral challenge that must be earned and thoughtfully given.
Rhett seeks forgiveness not just from Lainey, but from himself and, symbolically, from Penelope and her family. His long-held silence—choosing not to tell Lainey the full truth for years—makes forgiveness difficult because it raises questions about trust, responsibility, and courage.
Lainey, too, struggles with her own need to forgive not just Rhett, but her parents, herself, and even her sister. Forgiveness in this narrative is a layered process: it involves revisiting painful memories, asking uncomfortable questions, and confronting one’s own complicity in the silences that allowed the tragedy to fester.
The theme suggests that forgiveness is less an endpoint and more an evolution—it unfolds over time as truth comes to light and as emotional barriers are dismantled. The turning point is not a grand gesture but an intimate moment of truth by the bleachers, where vulnerability opens the door to understanding.
Later, the theme extends to Lainey’s mother, who embodies the generational implications of withholding forgiveness. Her eventual blessing of Lainey’s relationship with Rhett illustrates how acknowledging pain and misjudgment can lead to healing across generations.
Ultimately, the novel posits that true forgiveness is rooted in emotional honesty, courage, and the willingness to accept that people are more than the worst thing they have done.
The Lingering Effects of Trauma
The novel treats trauma as a living, breathing force that doesn’t fade with time unless actively addressed. Rhett’s psychological state is one of arrested development—emotionally stunted by the unresolved trauma of Penelope’s death.
His obsessive thought loops, nightmares, and compulsion to revisit the physical sites of the accident reflect a mind frozen in the moment of tragedy. Rather than coping mechanisms, these habits serve as reenactments of pain, forcing him to relive rather than move past the event.
Lainey, while more outwardly functional, carries a more sublimated form of trauma. Her grief is tied not only to loss but to uncertainty, and the ambiguity of what happened that day has become a mental minefield she avoids until Rhett forces her to confront it.
The novel shows how trauma affects not only individuals but their relationships, shaping how they give and receive love, how they perceive loyalty, and how they define closure. Even seemingly minor choices—who they date, where they live, what they avoid—are all dictated by their attempts to manage or suppress trauma.
The reemergence of Rhett in Lainey’s life destabilizes her sense of emotional safety. But it is this confrontation that eventually paves the way for healing.
The narrative suggests that trauma must be engaged with directly. It cannot be sidestepped or buried.
Only through painful truth-telling and emotional reckoning can characters begin to reframe their identities outside the shadow of loss.
The Role of Memory in Shaping Identity
Memory plays a central role in how characters in The One construct their identities and make meaning of their lives. The novel oscillates between past and present, using flashbacks and reflections to show how both Rhett and Lainey are shaped by what they remember—and by what they misunderstand or forget.
For Rhett, memory is a kind of haunting, a daily recurrence of the most traumatic moments of his life. These memories distort his self-perception and entrench him in guilt.
Lainey’s memories are more fragmented, often filtered through emotion rather than fact, which makes her susceptible to accepting half-truths or assumptions as reality. The act of remembering becomes a narrative device through which the characters attempt to reclaim control of their lives.
As new truths are revealed—such as the video footage proving Penelope’s state on the boat—the reliability of memory is challenged. This theme highlights how memories can be weaponized, misinterpreted, or idealized, and how memory can be both a source of connection and alienation.
By revisiting shared memories and correcting misunderstandings, Rhett and Lainey are able to reconstruct a more accurate and compassionate version of the past. This in turn allows them to reshape their present.
The novel presents memory as neither entirely reliable nor false. It is a lens through which emotional truth must be carefully parsed.
In doing so, it emphasizes the importance of clarity, communication, and perspective in reclaiming one’s narrative and forging a hopeful future.
