Conor O'Malley
Conor O'Malley is a thirteen-year-old boy thrust into an impossible situation, forced to navigate the complex terrain between childhood and maturity while his mother battles terminal cancer. Patrick Ness creates in Conor a protagonist who is simultaneously ordinary and extraordinary—a boy dealing with universal adolescent challenges while confronting the most devastating loss imaginable. What makes Conor such a compelling character is his profound internal conflict: he is angry, terrified, guilty, and desperately lonely, yet he attempts to maintain a fa?ade of normalcy and control.
Throughout the novel, Conor's most defining characteristic is his struggle with truth and denial. He has recurring nightmares about his mother's death, yet he refuses to acknowledge what he knows deep down—that she will not survive her illness. This psychological defense mechanism manifests in his interactions with the monster, who arrives not to save his mother, but to help Conor face the truth he cannot bear to accept. His famous statement, "I do not want you to save her. I want you to make it so that I never have to," reveals the depth of his emotional turmoil and the impossible burden he carries.
Conor's anger is perhaps his most visible trait, erupting in violent outbursts that shock those around him. When he destroys his grandmother's sitting room or when he beats Harry at school, these acts of destruction represent his desperate attempt to externalize the chaos consuming him internally. Significantly, Conor wants to be punished for these acts, seeking consequences that might match the magnitude of what he perceives as his greatest transgression—wanting his suffering to end, even if it means his mother's death. This guilt becomes the novel's emotional core, and Conor's journey toward accepting this human, understandable desire forms the heart of his character arc.
By the novel's conclusion, Conor undergoes a profound transformation. The monster's final tale forces him to confront his nightmare and speak the truth he has been suppressing: "I can't stand it anymore!" This moment of vulnerability and honesty, when he finally admits his exhaustion and conflicting desires, represents his emergence into a more mature understanding of grief, love, and human complexity. Conor learns that holding contradictory feelings simultaneously—loving his mother desperately while wanting his pain to end—doesn't make him a monster; it makes him achingly, beautifully human.
The Monster (The Yew Tree)
The monster is far more than a supernatural entity; it serves as a complex symbol of truth, storytelling, the natural world, and the bridge between life and death. Manifesting from the ancient yew tree visible from Conor's window, the monster arrives at 12:07 past midnight with a purpose that defies Conor's expectations. Unlike conventional monsters that inspire fear, this creature comes as a healer, teacher, and ultimately, a companion through Conor's darkest hours.
The monster's appearance is deliberately paradoxical—ancient yet vital, terrifying yet comforting, destructive yet nurturing. Composed of bark, branches, and leaves, it embodies the yew tree's historical associations with both death and healing, churchyards and medicine. This duality perfectly mirrors the novel's central themes and Conor's internal conflict. The monster's declaration—"I am not a messenger of God. I am the cure, the medicine"—establishes its role not as a miracle worker who will save Conor's mother, but as the force that will help Conor heal from the wound of unspoken truth.
What makes the monster particularly fascinating is its moral complexity. The three tales it tells deliberately subvert expectations, refusing simple categorizations of good and evil, hero and villain. The monster insists that these ambiguities reflect life's true nature, preparing Conor to accept that his own feelings cannot be neatly categorized as right or wrong. The monster's statement, "There is not always a good guy. Nor is there always a bad one. Most people are somewhere in between," challenges both Conor and readers to embrace moral and emotional complexity.
The monster's ultimate purpose is revealed when it demands Conor's truth—the fourth tale. In this moment, the monster transforms from teacher to witness, creating the safe space Conor needs to finally articulate his unbearable secret. The monster's presence during Conor's mother's final moments, visible only to Conor, provides the strength and support the boy needs to let go. As a character, the monster represents the power of storytelling itself to process grief, the necessity of facing painful truths, and the companion we sometimes need to walk us through impossible circumstances.
Conor's Mother
Conor's mother is a character defined largely by her absence and deterioration, yet she remains a powerful presence throughout the novel. Her terminal illness is the catalyst for all events, but Patrick Ness ensures she is more than simply "the dying mother"—she is a young woman fighting desperately for life, attempting to maintain normalcy for her son, and struggling with her own fear and exhaustion. Her characterization is rendered more poignant because we see her through Conor's eyes, as both the strong mother he needs and the fragile patient she has become.
One of the most heartbreaking aspects of her character is her determination to protect Conor from the full weight of her condition. She attempts to maintain routines, speaks optimistically about treatments, and tries to shield him from her worst moments. However, this protective instinct creates distance between them precisely when they need connection most. Conor notices the changes—her increasing weakness, her hair loss, her forced cheerfulness—and this awareness, combined with their inability to speak honestly about her prognosis, intensifies his isolation and fear.
Her physical transformation throughout the novel serves as a brutal timeline of cancer's progression. Ness doesn't shy away from the harsh realities: the treatments that make her violently ill, the exhaustion that keeps her in bed, the gradual wasting of her body. When Conor sees her after a hospitalization, he barely recognizes her, describing her as "like a photograph of his mum, rather than his actual mum." This observation captures both the disease's devastating physical impact and the psychological difficulty of watching a loved one become unrecognizable.
Despite limited direct appearances in the narrative, Conor's mother's character embodies unconditional love and the cruel unfairness of terminal illness. Her youth—she is still in her twenties—makes her fate even more tragic. In the novel's final scenes, when she can barely speak, she uses her remaining energy to tell Conor that she doesn't want to go, revealing her own desperate desire for life. This honesty, finally achieved, allows them both to acknowledge the truth and say goodbye. Her character ultimately represents not just loss, but the profound love between mother and child that persists even as death approaches.
Grandma (Conor's Grandmother)
Conor's grandmother is initially presented as a distant, formal figure who represents everything foreign and uncomfortable to the young protagonist. Living in a pristine house filled with antiques and maintaining rigid standards of behavior, she seems incapable of providing the warmth and understanding Conor desperately needs. Her insistence on being called "Grandma" rather than a more affectionate term, her disapproval of mess, and her structured approach to life create friction between them, making her seem like an antagonist in Conor's story.
However, as the novel progresses, layers of complexity emerge in her characterization. Beneath her stern exterior lies a woman facing her own devastating grief—watching her daughter die while simultaneously trying to provide stability for her grandson. Her rigidity and formality are revealed as coping mechanisms, ways of maintaining control when everything is falling apart. When Conor destroys her sitting room, her reaction—hurt, exhausted, and overwhelmed rather than purely angry—reveals her vulnerability and the tremendous burden she carries.
The grandmother's character arc involves learning to bridge the emotional distance between herself and Conor. She struggles to understand a boy so different from her daughter, to communicate across generational and temperamental divides, and to offer comfort when she herself is breaking. Her attempts at normalcy—enrolling Conor in school, maintaining routines, preparing meals—represent her way of showing love, even if Conor cannot initially recognize it as such. She lacks the natural ease with children that might make this transition smoother, but her determination to care for him is unwavering.
By the novel's conclusion, a tentative understanding develops between them. Grandma's forgiveness after Conor's destructive rampage, her presence at the hospital, and her quiet support during his mother's final moments demonstrate her capacity for compassion despite her rigid demeanor. She recognizes that Conor needs to be with his mother at the end and facilitates this crucial goodbye. Her character represents the imperfect but genuine love of family, the struggle of grief across generations, and the possibility of connection even between seemingly incompatible people. She will be Conor's future, his new family, and though neither finds this ideal, both are willing to try.
Harry
Harry serves as Conor's primary antagonist at school, but Patrick Ness crafts him as more than a simple bully. Harry represents the social cruelty that often surrounds illness and difference, the way communities sometimes isolate those experiencing tragedy rather than offering support. His bullying of Conor follows an unusual pattern—it is not violent or overtly aggressive, but rather insidious and psychological. Harry leads the school in a campaign of invisibility, ensuring that Conor is ignored, excluded, and treated as though he doesn't exist.
What makes Harry particularly interesting is the calculated nature of his cruelty. He understands that ignoring someone can be more painful than active persecution, and he wields this social power with precision. His treatment of Conor is described as making him invisible, which in many ways is more isolating than physical bullying would be. Harry knows that teachers are watching for obvious bullying and adjusts his tactics accordingly, demonstrating a manipulative intelligence that makes him a formidable antagonist despite his youth.
The dynamic between Conor and Harry shifts dramatically when Conor finally snaps and violently beats Harry. Significantly, Harry's reaction is complex—he is genuinely frightened by Conor's rage and the violence of the attack. This moment reveals Harry as more than a one-dimensional bully; he is also a thirteen-year-old boy confronted with something he doesn't understand and cannot control. His fear of Conor afterward suggests that his bullying may have stemmed partly from discomfort with Conor's situation, a childish inability to process the reality of terminal illness affecting a peer.
Harry's character ultimately serves multiple functions in the narrative. He represents the social isolation that often accompanies grief, the inadequacy of peer support when tragedy strikes, and the complex social dynamics of adolescence. His invisibility campaign, paradoxically, is what Conor sometimes desires—to be left alone, to not be pitied or treated differently. Yet it also demonstrates the cruelty of abandonment. Harry embodies the outside world's failure to properly support Conor, showing how society often fails children in crisis, leaving them to navigate impossible situations alone.
Lily Andrews
Lily Andrews occupies a unique and painful position in Conor's life—she is his former best friend, the person who knows his secret, and someone he both needs and resents. Before his mother's illness became common knowledge, Conor confided in Lily, sharing his fear and vulnerability. However, when Lily told her mother, who told others, Conor's private tragedy became public knowledge. This betrayal, though well-intentioned on Lily's part, destroyed their friendship and added another layer of loss to Conor's experience.
Lily's character represents the complicated nature of support and privacy, good intentions and their unintended consequences. She told her mother because she was worried and didn't know how else to help—a reasonable response for a thirteen-year-old facing information too big to carry alone. However, from Conor's perspective, this was an unforgivable violation of trust. His secret was the one thing he could control in an increasingly uncontrollable situation, and Lily took that agency from him. Her action, though motivated by concern, resulted in the pitying looks, the careful treatment, and the social isolation that Conor experiences at school.
Throughout the novel, Lily continues to reach out to Conor despite his rejection. She sits with him at lunch even when he refuses to acknowledge her, demonstrating a loyalty and care that persists beyond his anger. Her persistence suggests genuine affection and concern, as well as her own guilt over the breach of confidence. She represents the would-be supporters in Conor's life, the people who want to help but don't know how, whose attempts at comfort are rebuffed because Conor's pain is too great to share.
Lily's character also highlights the social complexities of adolescence during crisis. As Conor's former best friend, she occupies an ambiguous position—too close to be a stranger, too distant after the betrayal to be trusted. Her continued presence in his life, even at the margins, suggests that reconciliation might be possible, that relationships can survive breaches of trust, and that support sometimes means simply staying present even when pushed away. Though a relatively minor character in terms of page time, Lily represents the friendships that strain under the weight of tragedy and the question of whether they can be repaired.
Conor's Father
Conor's father is a character defined by absence, distance, and the complicated emotions surrounding parental abandonment and remarriage. Having moved to America and started a new family, he exists on the periphery of Conor's life, connected by occasional phone calls and rare visits. When he does appear in the novel, traveling to England during his ex-wife's health crisis, he embodies both the hope for rescue that Conor unconsciously harbors and the inevitable disappointment when that rescue doesn't materialize.
The father's characterization reveals a man struggling with his own limitations and failures. He is not portrayed as villainous, but rather as someone who has moved on with his life, created new commitments, and lacks the capacity or willingness to fully re-engage with his first family's crisis. During his visit, he takes Conor out, attempts normalcy through activities and conversation, but ultimately reveals that Conor cannot come live with him in America. This rejection, delivered with excuses about his new wife, new baby, and the impracticality of the arrangement, devastates Conor even though the boy had not consciously hoped for this outcome.
What makes this character particularly effective is how Patrick Ness presents him as neither wholly sympathetic nor entirely condemnable. The father clearly cares about Conor, feels guilty about the situation, and is genuinely distressed by his ex-wife's illness. However, his care and concern have limits—limits defined by his new life, his current family, and his unwillingness to sacrifice his own comfort and stability. He represents the painful truth that love and commitment are not always unconditional, that adults can fail children, and that some absences cannot be remedied.
The father's role in the narrative ultimately reinforces Conor's isolation and the reality that he must face his mother's death without the parental support structure most children take for granted. His inability to offer Conor a home or genuine refuge eliminates one potential escape route, forcing both Conor and readers to accept that the grandmother, imperfect as she is, represents Conor's only family future. The father's character serves as a reminder that not all wounds can be healed, not all parents can rise to the occasion, and sometimes the people we hope will save us simply cannot or will not.
