Isabelle is the protagonist of the 1997 timeline. Her story is one of survival, sacrifice, and maturation. At 17, she is forced to flee her boarding school after her cousins, the Sansas twins, are killed, making her the deciding vote in a bitter family feud over a mountain in her remote Andorran village. Her flight is one of strategic protection for her younger siblings, Xavier and Ana. This decision immediately establishes her core traits: resourcefulness, courage, and a deep sense of familial duty. To survive, she adopts the name “Joan,” a foundational act that represents the shedding of her old life and the adoption of a new, resilient identity forged by hardship.

Much of Isabelle’s story revolves around the tension between concealment and connection, highlighting the theme of Secrecy as an Act of Protection. Her invented identity as a French university student allows her to blend in with other pilgrims and form important alliances. While this keeps her safe, it also prevents her from being fully honest with the people who care about her. This conflict is most evident in her relationship with Peter, which highlights the conflict between her need for self-preservation and her desire for genuine connection. As their feelings for one another grow, Isabelle must choose whether to continue protecting herself through secrecy or trust someone with the truth. Her eventual confession marks an important turning point, allowing her to move from complete isolation toward genuine compassion and support.

Isabelle’s arc culminates in a series of sacrificial choices that define her as a tragic heroine. Throughout the novel, she repeatedly places the well-being of others above her own happiness, whether by remaining separated from her family, bargaining with Senor Sansas, or giving up the future she hoped to build with Peter. Even years later, living a quiet, unassuming life in Portugal, she agrees to marry Alberto, a kind but unremarkable man, signifying her acceptance of a life dictated by necessity rather than passion. Despite these hardships, Isabelle never loses her compassion or determination, making her one of the novel’s strongest and most resilient characters.

Peter serves as the important link between the novel’s two timelines, appearing as a young man in Isabelle’s 1997 narrative and as a guiding spiritual presence in his daughter Reina’s 2024 journey. In his youth, he is portrayed as a kind, observant, and quietly heroic figure. Unlike his boisterous brother David, Peter is introverted and thoughtful, his passion for photography a reflection of his desire to capture the beauty in the world around him. His attention to detail allows him to notice the struggles of others, particularly Isabelle’s, long before she is willing to discuss them openly.

Peter consistently demonstrates his kindness through action rather than words. He walks a considerable distance to buy Isabelle new hiking boots after noticing hers are broken, and he later risks his own safety to defend her during the assault at the albergue. These actions reveal a quiet determination beneath his calm exterior. His proposal to create the guidebook Wisdom of the Way together is both a practical solution to her financial struggles and a genuine expression of his desire to build a shared future with her. He embodies the romantic idealism of the Camino, finding both love and life’s purpose on its path.

Although Peter appears only in the 1997 storyline, his influence extends through the entire novel. His journal guides Reina’s journey, his photographs help uncover the truth about the past, and his values continue to shape the lives of those who loved him. In many ways, Peter functions as the emotional bridge connecting mother and daughter across time, ensuring that the choices made in one timeline continue to resonate in the other.

Matt initially appears to be the novel’s antagonist. As Reina’s workplace rival, he is competitive, arrogant, and frequently dismissive of her abilities. He is described as a “snake” who seemingly stole a story from an ailing colleague, Karen, to advance his career. His relentless teasing of Reina, nicknaming her “Velma,” and his overtly competitive nature establish him as a significant obstacle in her professional and personal journey.

As the novel progresses, however, the Camino gradually reveals a more complex and honorable character. His first sign of depth appears when he helps Reina with the injured pilgrim, Petra, and later when he heroically saves Ted from drowning in a river, an act that forces Reina to reconsider her harsh judgment of him. Even his professional history proves more complicated than Reina believed when she discovers that he was secretly ghostwriting for Karen to protect her job, not to sabotage it. Ultimately, the revelation that he is driven by the need to support his sister, Fiona, marks the turning point in his relationship with Reina. His ultimate willingness to share the byline for the feature article with her demonstrates his growth from a competitive rival to a collaborative partner.

Uncle David is a dynamic character who embodies the transformative power of the Camino. When he first appears in the 1997 timeline, he is a “springy” and restless young man, a foil to his more serious brother, Peter. He is outgoing, humorous, and sociable, often acting as a source of energy within the Camino group. His friendships with Jen, Joe, Isabelle, and Peter make him an important part of the community that forms on the trail, highlighting the theme of The Intimacy of Shared Struggle.

After the plane crash that kills Peter, David’s life takes a dramatically different course. Overwhelmed by grief and guilt, he disappears for 17 years, leaving Reina and her Aunt Robbie to fend for themselves. When Reina finally finds him operating the Sanctuary of the Gods, she discovers a man who has shed his past identity to live a life of selfless service. His mission to provide for weary pilgrims is his penance and his calling, a way of processing his own pain by alleviating the suffering of others.

Ultimately, David is an important bridge between the past and present, providing Reina with the missing pieces of her parents’ story and her own history. His decision to walk the final leg of the journey with Reina is an act of reconciliation, allowing him to finally step into the supportive familial role he abandoned years earlier. Unlike Reina and Isabelle, whose journeys unfold over the course of weeks, David’s change occurs over many years and includes mistakes, setbacks, and regret. However, his acknowledgement of his failures, particularly his abandonment of Reina, allows him to begin repairing the relationships he once left behind. In this way, his journey from a guilt-ridden runaway to a peaceful guardian of the trail illustrates a deep, alternative path to healing.

The Canadian brothers Ted and Ned function as mentor figures and represent Reina’s “Camino family.” They encounter Reina on the grueling first day and form an immediate bond, exemplifying the theme of The Intimacy of Shared Struggle. Ted, the elder brother, is sophisticated, witty, and acts as the group’s motivator. His relentless optimism and fatherly affection for Reina provide her with the emotional support she needs to persevere.

Ned is his foil, a good-natured and physically struggling man walking the Camino to improve his health at his doctor’s insistence. His journey is one of immense physical difficulty, yet his determination and humor are inspiring. Ned’s explicit struggle with his weight and his symbolic act of leaving a package of OREOs at the Cruz de Ferro represents the universal pilgrim’s journey of laying down a burden. Together, the brothers offer Reina a stable, caring presence that helps her build the confidence to complete her journey. Their steadfast support and humor are instrumental in her transformation.
