Grief as a Transformative Force
Through PJ, Ollie, Luna, and Sophie, Hartnett explores how grief transforms people by forcing them to rebuild connections and redefine their concept of family. She demonstrates that grief reshapes identity, relationships, and the capacity for love. Each character’s journey reveals a different dimension of grief’s power: PJ learns that aging and mortality do not preclude new beginnings, Sophie discovers strength in vulnerability, and Ollie and Luna begin the long process of integrating unthinkable trauma into their young lives.
After the unexpected death of his daughter Kate, who drowned in a cranberry bog as a teen, PJ drifts through life numbed by drink and nostalgia, clinging to the past through his house, memories, and regrets. PJ asserts “[…] the worst thing that can happen to anyone is the death of a child” (58). This overwhelming grief does not catalyze any personal growth for PJ; on the contrary, it leaves him trapped in an emotional quagmire symbolized by the bog itself. Kate’s death sets off a cascade of losses: his wife, his purpose, his self-respect. When he unexpectedly becomes guardian to Luna and Ollie, grief takes on a new shape. The death of his brother’s family compels him to think beyond himself. Caring for the children in their grief draws him out of the isolation of his own. Through this reluctant parenting, PJ rediscovers his capacity for love and responsibility, revealing how loss, though painful, can be a necessary path toward renewal.
Ollie and Luna’s loss is not a distant memory but a fresh wound that has destroyed their world. The sudden rupture from everything familiar, and their forced relocation to a great-uncle they barely know, amounts to the annihilation of their previous lives. Luna’s conviction that her real father is Mark Stackpole reflects her desperate search for a story that makes the unbearable more bearable. Their transformation is a slow process of learning to carry what cannot be set down. The road trip offers a suspended space where grief can exist without pressure to be resolved. Though still deeply wounded, by the novel’s end, Ollie and Luna have begun to transform from victims of tragedy into children who might someday integrate their loss into a fuller sense of self.
Sophie carries the complicated grief of losing her sister, witnessing her parents’ marriage collapse, and protecting herself through distance. Her decision to join PJ and the children marks her first step toward connection. The confined space of the Volvo forces her to balance her father’s recklessness with the children’s pain. In losing her own centrality, Sophie learns to balance multiple needs simultaneously and continues to show up despite exhaustion. Sophie’s transformation stems from learning to live with and love her father’s shortcomings, as well as openly discussing her sister’s reckless behavior. The novel states, “[…] sometimes people survive the impossible without even trying to pull a stunt” (129). Hartnett suggests that grief, while it breaks and remakes each of her characters, is also the force that binds them together, transforming loss into the very thing that restores their humanity.
Redemption Through Responsibility
PJ believes he has failed at everything that matters. In his eyes, he failed as a father, as a husband, and even as a lottery winner—squandering the windfall that represented a small, symbolic hope that he might somehow reverse his luck. These disappointments have left him stranded, haunted by guilt, and convinced that his best years are behind him. His failures erode his sense of self-worth, leaving him unable to envision a future not defined by regret. The messy house is a physical embodiment of this stagnation, filled with ghosts of the past he cannot release.
Unexpectedly becoming Ollie and Luna’s guardian forces PJ to become worthy of the trust placed in him. Caretaking gives PJ’s life renewed purpose. Where once he drifted through days at the bar, dispensing money without genuine connection, he now engages in the sustained, unglamorous work of showing up for specific people who need him. He expresses his newfound reason for living, “There is a reason I am still alive. I am still alive so I can protect you kids” (219). His failures, once a source of stagnation, become the foundation for empathy and growth. By the end of the novel, PJ has learned to live with his mistakes and transform failure into the humility and tenderness that make a genuine connection possible.
Sophie’s presence adds another layer to PJ’s redemption through responsibility. Sophie’s participation is both support and accountability, forcing PJ to acknowledge his history of poor judgment while demonstrating his commitment to doing better. Her willingness to trust him with this responsibility, despite their estrangement, offers PJ a chance to rebuild their relationship through consistent action rather than empty promises. A large part of PJ’s redemption comes through confronting his alcohol dependence. Hartnett uses his sobriety journey to explore the painful but necessary process of acknowledging addiction without being overwhelmed by social stigma. For years, PJ has used drinking as a self-punishment that allows him to avoid responsibility for his pain. Alcohol becomes both his refuge and his prison. When he begins to care for Luna and Ollie, however, he can no longer afford the luxury of self-destruction. The demands of protecting and nurturing them force him to confront the habits that have kept him emotionally absent. Hartnett depicts PJ’s sobriety not as a linear, one-time event but as a fragile, ongoing act of courage. He falters, but each day he chooses not to drink is a victory. By facing his addiction, PJ begins to dismantle the shame that has defined him and replaces it with accountability, compassion, and a hard-won sense of self-respect. This gradual healing also heals his relationship with Sophie, whose own journey toward forgiveness depends on seeing her father as a flawed but evolving man rather than the failure she once believed him to be.
Finding Connection Amid Life’s Fragility
Death shadows the road trip, literally following the family from stop to stop. Someone dies at nearly every place PJ, Sophie, Luna, and Ollie visit, with the ominous but lovable cat serving as a signal that death may not be entirely something to fear. In this book, death permeates ordinary life, forcing the characters to reckon with both the inevitability of loss and the persistence of human connection. The constant presence of death forms the emotional landscape through which Hartnett explores how love and connection endure, even when mortality makes them temporary. The story features death in many forms, as Hartnett asks what it means to keep reaching for one another alongside the knowledge that loved ones will one day disappear.
The family road trip that forms the narrative engine of this novel doubles as a spiritual odyssey, as each member of the family confronts the harsh realities of loss and grief. Death is omnipresent, yet so is love. The pattern of mortality underscores the novel’s central paradox: that the certainty of death is what gives connection its urgency and grace. In facing death repeatedly, the characters learn to live more fully. Hartnett punctuates the theme of mortality and fragile connection with a twist at the novel’s conclusion, revealing that it is Ivy, not PJ, who faces certain death. Ivy’s terminal brain cancer forces the characters to confront the ultimate unpredictability of life. Throughout the journey, PJ has been struggling to reconcile his past failures and to rebuild his capacity for love, seemingly preparing for his own mortality. The twist shows that death rarely arrives on schedule or according to expectations. In this way, Hartnett emphasizes that the fragility of life is universal. The abrupt end of the road trip underscores how quickly circumstances can change. Yet, it also highlights the importance of connection: PJ, Sophie, and the children must confront this new loss together, reaffirming that love and care are meaningful precisely because life is finite. As Ollie states, given the fragility of life, “It’s good to not be alone” (240). Ivy’s mortality deepens the novel’s meditation on grief, showing that human relationships are sustained not by certainty or control but by presence, attentiveness, and the courage to engage fully with one another in the face of inevitable loss.
Hartnett emphasizes that human connection persists even in the face of mortality, often through memory and the lingering presence of those who have died. “[…] you hold on to things because you know better than anyone else there’s nothing in the world anyone can actually hold on to” (72). When Kate’s hat appears to speak, and when PJ sees what he believes is the ghost of his mother at Ed Cobb’s funeral, these magical moments symbolize PJ’s confrontation with mortality, reminding him that death is an ever-present force and that those who have passed remain part of the lives of the living through memory and reflection. Psychologically, these intangible events reflect PJ’s ongoing struggle with unresolved pain and a source of subtle reassurance. The novel establishes that while life is fragile and death is inevitable, the connections humans nurture through love, memory, and presence give meaning and resilience to the human experience.
