Characters 

Owen Dawson

Owen Dawson emerges as a deeply complex character. He is initially presented as a successful and emotionally unavailable real estate entrepreneur in New York City.

While his exterior is polished, pragmatic, and a bit guarded, the narrative steadily peels back his layers. He is revealed to be a man shaped by emotional restraint and past disappointments.

His encounter with Devyn challenges his established boundaries. What begins as a one-night stand transforms into a journey of emotional awakening.

He becomes entangled in the chaotic, heart-wrenching life Devyn leads with her siblings. Owen is dependable and quietly heroic.

He bails Heath out of trouble without fanfare, stands by Devyn during legal proceedings, and uses his resources to stabilize a crumbling situation. His jealousy, especially in moments involving Robert and Brayden, never escalates into toxic masculinity.

Instead, it highlights his vulnerability and desire for something real. By the time he confesses his love and opens up about his fears and childhood wounds, Owen completes a meaningful arc.

He transforms from emotionally insulated to fully present and committed. His proposal, more of a symbolic promise than a traditional gesture, solidifies his respect for Devyn’s autonomy and his intent to walk beside her, not ahead of her.

Devyn Marks

Devyn Marks is a portrayal of resilience, sacrifice, and emotional complexity. When readers first meet her, she is navigating a life far more difficult than her years suggest.

She juggles the roles of older sister, temporary guardian, and emotionally hesitant romantic partner. Her past with Robert, a self-absorbed actor, has left her cautious and defensive.

Yet she never allows her bitterness to fully harden her. She is fiercely protective of Heath and Hannah.

The emotional labor she performs is immense, from fending off CPS to hunting down their unreliable mother, Vera. Devyn’s inner conflict lies in the balancing act between longing for independence and fearing vulnerability.

Owen disrupts her armor, and while she pushes back against his interventions at first, she eventually learns to trust him. Not because she needs saving, but because he proves he respects her agency.

Her evolution is marked by her growing confidence in both her romantic and professional life. When she accepts a role in Owen’s company, it’s not a concession—it’s an earned partnership.

Her story is not just about romance but reclaiming control over a chaotic life. She shapes it into something meaningful for both herself and the ones she loves.

Heath Marks

Heath is portrayed as a troubled yet deeply well-meaning teenager. He carries a disproportionate share of adult responsibilities.

Initially seen as a prankster—dyeing a neighbor’s cat, skipping school—his actions are quickly revealed as symptoms of his underlying anxiety. He desperately wants to support his sister and protect Hannah.

He even attempts to earn money secretly. Heath’s confession about hoarding money from odd jobs reflects his desperate need for control in a world where adults have repeatedly failed him.

His relationship with Owen begins with wary skepticism but evolves into admiration and trust. Owen proves himself consistent and safe.

Heath’s growth is less about transformation and more about stabilization. He doesn’t need to change who he is, but rather be assured that he no longer has to bear the burdens alone.

By the end of the novel, Heath is thriving in school. He is living in an environment of security, thanks largely to Devyn’s guardianship and Owen’s support.

Hannah Marks

Hannah is the quieter of the two siblings. She is often overshadowed by the more overt crises involving Heath and Devyn.

Yet her presence adds a layer of emotional texture to the narrative. She is artistic, involved in theater, and perhaps the most emotionally transparent member of the family.

Her need for consistency and emotional safety is palpable. Like Heath, she quickly warms to Owen once she senses his reliability.

Hannah’s interactions with Devyn highlight the burdens Devyn carries as a maternal figure. Her warmth and trust serve as a silent motivator for Devyn to keep fighting.

By the time the court grants custody to Devyn, Hannah’s emotional and creative flourishing becomes symbolic. It represents the new stability the family has achieved.

Robert

Robert is less a fully fleshed-out character and more a necessary contrast to Owen. He is the archetypal toxic ex—possessive, dismissive, and manipulative.

His reentry into Devyn’s life serves to underline just how much she has grown. She is far removed from the emotional compromises she once accepted.

Robert views Devyn more as an accessory to his own success than as a person with agency and responsibility. His attempts to reclaim her fail not because of dramatic confrontations but because Devyn has evolved.

She has reached a place where his antics no longer hold sway. In essence, Robert exists to show the reader what Devyn is not returning to, and why Owen’s quiet loyalty is worth so much more than Robert’s shallow charisma.

Vera

Vera, the absentee mother of Heath and Hannah, embodies instability, neglect, and the long-term consequences of addiction or emotional absence. She is found squatting in a broken-down RV.

Her character represents the systemic failures and personal choices that force children like Devyn to grow up far too soon. Yet the novel resists making her a pure villain.

Her refusal to take responsibility is heartbreaking. However, her eventual sobriety in the epilogue hints at a slow, difficult redemption.

Vera’s arc, though minor in screen time, plays a pivotal role in shaping every other character’s journey. She influences Devyn’s overdeveloped sense of responsibility, Heath’s anxiety, and even Owen’s protective instincts.

Themes 

Emotional Availability and the Struggle to Trust

One of the central themes that defines both Owen and Devyn’s emotional trajectories is the tension between emotional availability and the difficulty of learning to trust again after past disappointment. Owen begins the story as a man who has grown comfortable behind emotional walls, built likely from past relationships or familial detachment, making genuine vulnerability feel both foreign and risky.

Devyn, in contrast, is emotionally active and responsible in the lives of her siblings, yet romantic trust is more complicated for her due to the unresolved entanglement with Robert and the chaotic unpredictability of her mother, Vera. Their first encounter might be described as spontaneous, but what follows is a slow, often reluctant emotional courtship where both characters navigate their own emotional baggage.

Owen’s struggle is not just in expressing feelings, but in even understanding that his guarded nature is itself a form of self-protection. Devyn, despite her nurturing role, is also resistant to exposing herself to romantic vulnerability because her past has shown her that men—like Robert—cannot be relied on.

As their relationship progresses, trust is built not through grand gestures but through acts of reliability and patience. Owen’s support through the legal battles and chaotic family moments gradually chips away at Devyn’s hesitation, while her consistent integrity allows Owen to risk emotional honesty.

The story frames trust not as a singular decision but as a cumulative process, where stability and presence create the foundation for emotional openness.

Found Family and the Reimagining of Home

The novel explores the idea that family is not merely a matter of blood ties but of choice, loyalty, and shared responsibility. Devyn’s relationship with her younger siblings—Heath and Hannah—extends far beyond what is expected of a sister.

She becomes a de facto parent, driven by a moral commitment to give them the emotional stability that their biological mother has failed to provide. Owen, at first a stranger, gradually becomes another cornerstone in this improvised family structure.

What begins as a reluctant involvement in a prank gone wrong evolves into a deeply rooted sense of belonging and responsibility. The theme develops further when the state threatens to tear this patchwork family apart, and both Devyn and Owen take active legal and emotional steps to keep it intact.

The concept of home is also redefined. It is not a static space, but rather a dynamic environment shaped by love, sacrifice, and emotional safety.

Owen’s home, initially a symbol of wealth and detachment, transforms into a space of warmth and familial connection. The novel challenges traditional notions of family by showing that care, consistency, and emotional availability are the true markers of a familial bond.

This reimagining of home and family adds depth to the story’s emotional stakes and reaffirms that chosen families can offer a level of security and belonging often missing in biological ones.

Redemption Through Love and Responsibility

Redemption in this story does not occur through dramatic transformation but through gradual, sustained actions that reflect growth and reparation. Owen, whose past has been marked by emotional isolation, begins to understand love as something rooted in presence and reliability.

His arc is one of moral expansion: from someone who avoids attachments to someone who nurtures them. His redemption is tied closely to his increasing willingness to be vulnerable, to show up even when things are uncomfortable, and to take on responsibilities that do not benefit him directly.

Similarly, Devyn’s redemption is internal. She starts the story feeling overwhelmed, maybe even unsure whether she’s capable of handling everything that has fallen into her lap.

Through perseverance, she proves to herself and others that she is not only capable, but indispensable to her siblings’ well-being. Her acceptance of Owen’s love is a form of personal redemption—it’s the moment she allows herself to believe she deserves stability and affection without strings.

Even secondary characters like Vera are given a redemptive arc, albeit with limitations. Her eventual steps toward sobriety and establishing boundaries, though late, hint that even deeply flawed individuals are capable of change.

The novel’s portrayal of redemption is grounded and realistic. It emphasizes that while not every character may be fully transformed, the effort to do better—especially for the sake of others—holds profound value.

Gender Roles, Power, and Self-Worth in Relationships

The book subtly critiques traditional gender roles and offers a modern perspective on power dynamics in romantic and familial contexts. Devyn, though initially dependent on the goodwill of others, quickly emerges as a capable leader and protector within her household.

She is the one taking legal action, managing the household, and making hard choices—all traditionally “masculine” roles in literature. Conversely, Owen, though financially and professionally powerful, learns to derive strength from emotional openness and vulnerability.

Their relationship rebalances stereotypical dynamics. Instead of Owen rescuing Devyn, their bond is built on mutual empowerment.

Owen respects Devyn’s independence and does not impose his wealth or authority as a way to win her over. When he offers her a job in his real estate firm, it is not out of pity but in recognition of her talents.

Devyn’s hesitation and eventual acceptance show her growth in self-worth and her ability to distinguish between being helped and being valued. Robert serves as a foil to Owen—he represents the old model of masculine power: controlling, dismissive, and emotionally unavailable.

His downfall is not dramatic, but it is essential in clarifying what kind of partner Devyn wants and deserves. The theme of power also extends to the legal battle, where Devyn takes control of her family’s fate, reinforcing the message that women are capable of wielding both emotional and institutional power.

The story reinforces that true partnership exists when both individuals respect and uplift each other’s agency.
