Though she dies early in the novel, Kathy remains a central and active presence throughout the narrative, functioning as the story’s primary catalyst. Her existence is filtered entirely through Sally’s memory, which reconstructs her as a complex figure whose influence persists long after her death. In Sally’s recollection, Kathy embodies the confidence and worldly knowledge of an older sister—the person who explains the ways of the world, from constellations to boys, and serves as Sally’s primary role model. Described as a charismatic “natural” (5) performer, Kathy represents a vision of poised, popular girlhood that Sally initially emulates. It is through this loving, albeit subjective, lens that the novel explores The Formative Power of Sibling Bonds, examining the myriad ways Kathy’s life and death inform the person Sally becomes.

Through Sally’s memories, Espach paints Kathy as a round character with her own subtle complexities. While she is a protective guide to Sally, she can also be dismissive, creating a private world with her friends that excludes her younger sister. Her confidence wavers, particularly in her initial shyness around Billy, revealing a vulnerability that emphasizes her humanity in contrast to the myth she becomes in death. Kathy’s narrative role is not just to be remembered, but to actively shape the lives of those she left behind. Her death is the event that fractures the Holt family and ignites the forbidden, grief-stricken love between Sally and Billy, making her the silent, unmovable center of their shared trauma.

Billy Barnes is Sally’s romantic counterpart whose life becomes inextricably linked with hers through the shared trauma of Kathy’s death. He is first introduced as Kathy’s crush—a figure of reckless masculine charm, a popular athlete known for “doing stupid things” (8) like jumping off the school roof. This early characterization establishes him as a classic archetype of charismatic youth whose fearlessness is both his defining trait and his eventual downfall. The car accident that kills Kathy transforms him from this idealized boy into a tragic figure, permanently marked by the physical wounds and scars that symbolize his emotional suffering. The accident shatters his identity as a star athlete and casts him as the villain in the town’s narrative, forcing him onto a path of self-loathing and penance.

Following the accident, Billy’s journey is defined by his profound sense of guilt—the central force behind his actions, from his attempts to die by suicide to his decision to enter a seminary as a form of self-abnegation. His relationship with Sally is rooted in The Intersection of Love, Guilt, and Shared Trauma. Their secret conversations become his only outlet for the grief and remorse he cannot express to anyone else. While he is initially Kathy’s boyfriend, his most meaningful and transformative bond is with Sally, the only other person who understands the true complexity of his grief. His physical scars are a constant, visible reminder of his psychological burden, a pain that isolates him from his peers and his former life.

Billy’s character development is a journey of rebuilding an identity in the aftermath of catastrophic loss. Stripped of his athletic future and social standing, he must find a new purpose. His brief time in the seminary shows his attempt to find redemption through faith, but his ultimate path lies in returning to his roots. By taking over his family’s business, Bill’s Tree and Garden, he finds a quieter, more grounded form of healing in nurturing life. This transformation from a reckless boy to a thoughtful, scarred man is a testament to his resilience. He never fully escapes the shadow of the accident, but he learns to live with its consequences, and his enduring connection to Sally serves as the novel’s emotional anchor.

Sally’s mother, Susan, embodies the devastating impact of grief on a person’s identity and relationships. Before the accident, she and Richard have built an archetypically stable, orderly suburban life. Susan’s insistence on rituals, like laying out clothes for the next day, and her desire for the White Couch symbolize her hope for a perfect, beautiful life for her family. This carefully constructed world is irrevocably shattered by Kathy’s death, and her character becomes a vessel for exploring the chaotic and consuming nature of a parent’s grief. The white couch, once a symbol of her pristine dreams, becomes stained by the messy reality of trauma when Sally vomits on it, marking the end of the family’s innocent aspirations.

After Kathy’s death, Susan’s grief becomes the central force in her life, manifesting as severe depression, dependence on drugs and alcohol, emotional volatility, and a desperate search for meaning. Her pain is palpable and often public. She turns to a psychic, Jan, to maintain a connection with Kathy, demonstrating her need to create a narrative in which her daughter’s spirit is still accessible. This reliance on an external storyteller highlights the subjectivity of memory as a central theme in the story, as she actively seeks a version of the past and present that she can endure. Susan’s journey provides a portrait of arrested grief—she becomes trapped in her loss, unable to move forward, which creates a rift between her and the other members of her family who are trying, in their own ways, to survive.

Richard, Sally’s father, responds to tragedy with a stoicism that contrasts sharply with his wife’s expressive grief. His character is defined by a deep-seated concern for safety, a trait informed by his job as a safety consultant. He’s a man who sees potential danger everywhere, from the dying maple tree outside his daughters’ window to the lack of a hard hat on a worksite. He approaches the world with a practical, methodical mindset, attempting to impose order and prevent disaster. This worldview is challenged by Kathy’s death, a senseless accident that defies logic and control. In its aftermath, he retreats into emotional containment, processing his sorrow through anger and a quiet, isolated mourning.

Richard’s grief manifests primarily as a quiet but intense anger directed at Billy. Forbidding Sally from contacting Billy and threatening to sue, he seeks a tangible target for his pain, viewing punishment as the only logical recourse for the carelessness that led to the accident. This stance isolates him from Susan, who seeks a more spiritual form of consolation, and from Sally, who shares a complex bond with Billy. Richard often retreats to his red leather “Man Chair,” a physical space that symbolizes his emotional withdrawal from the family. While he struggles to articulate his feelings, his actions, like his obsessive need to cut down the dead trees, reveal a man trying to protect his family from further harm in the only way he knows how.

Peter Heart serves as a foil to Billy, representing a life of stability, ambition, and conventionality—one he offers to Sally, but she ultimately cannot choose. Espach characterizes Peter by his traditional, high-achieving goals. He’s the student body president, an accomplished athlete, and a reliable, “good guy.” His relationship with Sally is uncomplicated by the deep, shared trauma that defines her connection to Billy. Peter’s inability to comprehend the intensity of Sally’s grief is evident when he dismisses her bond with Billy as “fucked up” (234), a comment that underscores the profound gap between his worldview and hers. He represents a path of social acceptability and emotional simplicity, but these very qualities make him an inadequate partner for Sally, whose life has been irrevocably shaped by tragedy.
