The novel’s co-protagonist, April, begins the novel with her identity fractured by the conflicting demands of motherhood, marriage, and her own sense of self. A core aspect of her personality is a deep-seated need to nurture and find purpose, first established through her work as a dedicated tutor for students with dyslexia, like Jonathan Gutierrez. This desire for purpose, however, becomes a source of internal and external conflict. After leaving her career to raise her children, she feels her identity diminish, leading to a deep sense of isolation. Her attempts to manage and fix the lives of those around her, including Leo, are often perceived by him as a form of control, revealing a fundamental disconnect in their relationship and her own unaddressed need for validation.

April’s character is deeply shaped by The Ramifications of Unresolved Trauma, specifically postpartum depression. After the births of both Sadie and Otto, she experiences periods of intense loneliness and self-loathing, feeling disconnected from her own body and the idealized role of a mother that she feels she has failed to inhabit. Leo’s emotional withdrawal compounds this emotional state, leaving her feeling unseen and unsupported. Her subsequent affair with Cody Blanchard acts as a desperate symptom of this internal conflict rather than a passionate romance. A misguided act of self-sabotage and an attempt to feel desired and valued at a time when she feels invisible, this becomes the focal point of the marital crisis; however, the narrative reveals it to be the culmination of years of unspoken pain and unmet needs from both partners. When confronted by Leo’s singular focus on the affair, she forces a more complex reckoning by stating, “You were gone before you left” (206), demanding that he acknowledge his own role in their estrangement.

Ultimately, April embodies the theme of Preserving Love Through Shared Memories. She acts as the keeper of her family’s history, both consciously and subconsciously. Her instinctive decision to save Leo’s novel, Seventh City, from the house fire symbolizes her unwavering belief in him and her preservation of the foundation of their love, even as their shared life is literally burning. The notes that she wrote in the margins serve as a tangible archive of their relationship, becoming the catalyst for Leo’s change of heart. April’s journey consists of reclaiming her own narrative, insisting that the full story of their marriage, with all its complexities, be remembered. She understands that their shared past can’t be reduced to a single act of betrayal and that true reconciliation requires acknowledging the slow erosion that preceded the final collapse.

As the matriarch of the Russo family, Deb serves as the story’s emotional anchor. Her identity is rooted in her role as a caretaker, a position she has occupied since she was a teenager caring for her grieving father. This is most visibly expressed through her cooking, which constantly provides comfort and a sense of control while conveying her love for her family. While she occasionally resents the unending demands of this role, her actions consistently demonstrate a fierce and pragmatic devotion to her loved ones. Her home on Lexington Avenue is the hub of family life, a place of stability that contrasts sharply with the chaos engulfing April and Leo.

Deb’s significance in the broader story deepens with the revelation of her own marital history with Billy. The disclosure that their “perfect” marriage began as a shotgun wedding, born of obligation rather than love, provides an important parallel to April and Leo’s struggles. It implies that love is an active, evolving process rather than a static state, capable of growing from difficult beginnings. This backstory complicates her children’s understanding of love and commitment, suggesting that endurance and loyalty can forge a bond as strong as one born from initial passion. As Billy’s Alzheimer’s disease progresses, Deb transitions into the role of his primary memory keeper. She becomes the guardian of their shared history, embodying the central argument of Preserving Love Through Shared Memories. Her steadfast care for Billy, even as he begins to forget her, illustrates that love persists as an active practice, sustaining a relationship’s core identity even as memories are lost.

Billy is a key supporting character whose struggle with early-onset Alzheimer’s disease acts as a catalyst for the novel’s primary conflicts, furthering reinforcing the theme of Preserving Love Through Shared Memories. Before his diagnosis, Billy is defined by his gentle humor, unwavering loyalty, and deep love for his family. As a good-natured patriarch and a successful dentist, often grounding his family with his steady presence and corny jokes, he shows a stable, traditional form of fatherhood that Leo both admires and feels unable to achieve.

As his illness progresses, Billy’s character becomes a vessel for the novel’s exploration of memory, identity, and love. Moments of confusion, such as mistaking his granddaughter, Sadie, for his daughter Josie or believing Leo to be one of his own sons, paradoxically reveal deeper emotional truths about his perception of family. Even when he doesn’t recognize Deb, he recalls his love for his wife and enjoys intimate moments with her, like dancing. These episodes strip away chronology, leaving behind the core feelings of love and connection that defined his life. Billy’s condition forces his family to confront what remains of a person when their memories fade, questioning whether love is contingent on a shared, remembered past. His journey suggests that an emotional, instinctual form of love can persist even after cognitive recognition is gone.

Josie and Cameron function primarily as foils to their sister, April, and as representations of different life paths and coping mechanisms. Josie, an actress, is dramatic and emotionally transparent, and her expressive nature contrasts with April’s internalized struggles. Josie’s role in the plot is often to release narrative tension with humor or force uncomfortable conversations that others avoid; in short, she pushes the family to confront its dysfunctions. Her decision to get tested for the genetic marker for Alzheimer’s highlights a proactive but anxious approach to confronting her own fears, unlike her siblings’ initial avoidance.

The quiet, thoughtful Cameron offers a sense of stability and convention, following a traditional path from college to career and marriage. His steady relationship with his fiancée, Rachel, provides a narrative counterpoint to the turmoil of April and Leo’s dissolving marriage, implicitly asking what it takes to build and maintain a stable partnership. His pragmatic response to his father’s diagnosis (such as implementing location tracking on his phone and using sticky notes as reminders) showcases his role as a problem-solver within the family. Together, the siblings highlight the different ways in which individuals navigate family crises and seek to redefine their own lives in the shadow of their parents’ legacy.
