Olivia is grateful for his intervention, and though their interactions continue to be filled with tension, there is a growing mutual respect beneath their banter.
As Thanksgiving progresses, Olivia finds herself spending more time with Aaron. She discovers that her plans to spend Christmas alone due to her chaotic roommates and lack of travel options will leave her isolated.
Meanwhile, Aaron’s increasing protectiveness over her situation further complicates Olivia’s feelings. Despite their playful antagonism, there is a growing bond between them, and Aaron begins to show more consideration for her than she ever expected.

Olivia, unsure of the authenticity of Aaron’s feelings, is affected by this public declaration. At the gala, Tessa, Aaron’s ex, makes disparaging comments that make Olivia question where she stands in Aaron’s life.
Despite these complications, Olivia and Aaron continue to grow closer, with their feelings becoming more evident. Their relationship is tested, however, when Olivia faces the challenge of securing her own apartment, which brings up feelings of independence and self-reliance.

Characters
Olivia Griswold
Olivia Griswold is a complex character who returns to Atlanta after years away, seeking to rebuild her life and reconnect with her family. Her journey is marked by her internal struggle with her past, particularly the tension she feels toward Aaron Marino, her brother Jake’s best friend and former high school nemesis.
Olivia has a history of harboring resentment toward Aaron for the way he treated her during their youth, leading her to fantasize about retribution. However, as she interacts with him in the present, she finds herself torn between her lingering anger and a growing attraction to him.
Olivia’s development throughout the story is closely tied to her emotional healing, as she grapples with the wounds left by her past, particularly the sense of abandonment she feels from her family. Her relationship with Aaron forces her to confront her vulnerabilities and to slowly open herself up to love and connection.
Despite her initial resistance to Aaron, Olivia’s gradual shift in perspective reveals her deepening feelings for him, highlighting her inner transformation from skepticism to acceptance. Her evolving relationship with Aaron offers her a chance at healing and finding a sense of belonging, something she has longed for but has been unable to achieve due to her tumultuous family dynamics.
Aaron Marino
Aaron Marino is the captain of the Atlanta Cyclones hockey team, a position that reflects both his leadership qualities and his personal transformation. Initially presented as a cocky and playful figure, Aaron’s true character emerges as the story unfolds.
He is aware of Olivia’s disdain toward him but responds with flirtatious banter, clearly intrigued by her despite their antagonistic history. Over time, Aaron’s character deepens as he begins to display more genuine care for Olivia.
His protective instincts surface when he prevents her from consuming food she’s allergic to, demonstrating a side of him that is thoughtful and attentive. As the narrative progresses, Aaron’s relationship with Olivia challenges his previous avoidance of serious commitments.
His actions reveal his vulnerability and a longing for a deeper connection, particularly as he faces the fallout from his public image being complicated by ex-girlfriend Brandi’s media antics. Throughout the story, Aaron evolves from a self-proclaimed commitment-phobe to a man who unapologetically pursues Olivia, openly declaring his love for her in a public and heartfelt gesture.
His transformation is one of emotional growth, where he learns to embrace his feelings and move past his fear of vulnerability in order to be with the woman he loves.
Jake Griswold
Jake Griswold, Olivia’s protective older brother, serves as a grounding presence in the story. His initial concern for Olivia’s well-being drives much of his actions, particularly in his interactions with Aaron.
While Jake is skeptical of Aaron’s intentions toward his sister, his relationship with Olivia is one of deep loyalty and care. As a professional hockey player, Jake’s role within the Cyclones team adds an additional layer of complexity to the dynamics between him, Aaron, and Olivia.
Jake’s protective nature is a consistent theme throughout the narrative, and his evolution lies in his eventual acceptance of Olivia’s relationship with Aaron. While initially uncomfortable with their budding romance, Jake comes to understand that Aaron genuinely cares for his sister, marking a significant shift in his own perspective on relationships and trust.
His role in the story provides a sense of stability and grounding, helping to anchor Olivia as she navigates her emotional journey.
Brandi
Brandi, Aaron’s ex-fiancée, plays a pivotal role in the external conflict of the narrative. Though she initially appears as a secondary character, her actions create significant tension, particularly with her stunt involving a cockroach named after Aaron, which causes a media frenzy.
Brandi’s behavior disrupts the peace Aaron has worked to build, especially as she makes her presence felt at key moments, such as the Christmas gala, where she continues to cause turmoil. Despite her role in stirring up trouble, Brandi is more than just a disruptive figure.
Her actions reflect the complexities of Aaron’s past relationships and his struggles with commitment, providing a contrast to the love and security he seeks with Olivia. Brandi’s impact on the story is felt through the way she forces Aaron to confront his past and, in doing so, makes his relationship with Olivia all the more significant.
Dallas Cooper
Dallas Cooper, a teammate of Jake’s, adds an element of playful flirtation to the story. His interest in Olivia is clear, and his flirtations are a source of both humor and tension, particularly as they highlight Olivia’s internal struggle with her feelings toward Aaron.
Dallas’s advances serve as a foil to Aaron’s more genuine pursuit of Olivia, underscoring the emotional depth of her growing attraction to Aaron. While Dallas is charming and fun, he is ultimately more of a catalyst for Olivia’s self-reflection than a genuine romantic interest.
His presence in the story serves to further highlight Olivia’s confusion and complexity in her relationships, especially as she comes to realize what she truly wants and needs.
Sofia
Sofia, Jake’s girlfriend, is a minor but important character who contributes to the warmth and family dynamics of the story. Her role in the narrative is to provide support and act as a sounding board for Olivia as she navigates her feelings for Aaron.
Sofia’s presence in the story offers a contrast to the tension between Olivia and Aaron, providing a more stable and positive relationship dynamic. Through Sofia, the reader sees the potential for genuine connections and the possibility of love and acceptance within a family, even as Olivia grapples with her past and uncertain future.
Themes
Family and Connection
At the core of Holiday Hostilities is the theme of family and connection, which drives much of the character development and narrative. Olivia Griswold’s return to Atlanta marks a pivotal moment in her life, as she seeks to reconnect with her brother, Jake, and build a sense of belonging in a city she had once left behind.
Her complicated relationship with her parents, especially her father’s struggles and her mother’s multiple remarriages, has left Olivia feeling isolated and distant from family bonds. In contrast, Aaron Marino’s warm, welcoming family traditions provide a stark contrast to Olivia’s emotionally cold upbringing, making her feel like an outsider when it comes to holiday celebrations.
Despite their differences, Aaron’s family slowly becomes a source of comfort for Olivia, offering her the familial warmth she had longed for. Aaron, too, experiences his own familial struggles, including his tense relationship with his ex-girlfriend Brandi and the pressures that come with his public image.
Throughout the story, Olivia and Aaron’s relationship evolves from an awkward dynamic to one where both characters come to realize the importance of supporting one another through their personal challenges. Ultimately, their shared experiences and growing connection with each other and their respective families allow them to find healing and a deeper sense of belonging.
Personal Growth and Healing
Another significant theme in Holiday Hostilities is personal growth and healing, particularly for Olivia. Olivia’s return to Atlanta is not just about reuniting with her family but also about confronting the emotional scars of her past.
The trauma of her family’s dysfunction and her own unresolved issues have shaped her into a guarded, independent woman who is wary of emotional attachment. However, through her interactions with Aaron, Olivia begins to confront her past and the walls she has built around herself.
Aaron, initially perceived as a playboy and a source of irritation, becomes a catalyst for her emotional healing. His patience, kindness, and genuine care challenge Olivia’s preconceived notions about love and commitment.
As they navigate their complicated relationship, Olivia opens up to Aaron in ways she never expected, allowing herself to be vulnerable and embrace her feelings for him. This journey of personal growth culminates in her realization that she can trust in both Aaron and her own ability to love and be loved.
Aaron, too, experiences growth as he sheds his reluctance to commit and faces his own fears of vulnerability. His evolving relationship with Olivia represents not just a romantic connection but also his personal transformation into someone willing to embrace love and responsibility.
Attraction and Love
The theme of attraction and love plays a central role throughout Holiday Hostilities, with Olivia and Aaron’s relationship shifting from animosity to romantic tension. From their first interactions, there is a clear spark between them, marked by playful banter and underlying attraction.
Olivia’s initial resistance to Aaron’s charm is rooted in the emotional baggage she carries from their past and her reluctance to open herself up to romantic possibilities. However, as they spend more time together, their chemistry intensifies, and Olivia begins to question her feelings for him.
This attraction, while initially masked by humor and antagonism, soon blossoms into a deeper connection. For Aaron, his attraction to Olivia evolves from physical desire to a more profound emotional attachment, as he begins to see her not just as his best friend’s sister but as someone he genuinely cares about.
The progression of their relationship, marked by moments of tenderness, humor, and raw honesty, culminates in the realization that their connection goes beyond mere attraction. Their love is built on mutual respect, understanding, and a willingness to face their emotional challenges together.
The theme of attraction and love in the story explores how complex and transformative romantic relationships can be, with Olivia and Aaron’s evolving feelings for each other offering a powerful narrative of emotional growth and connection.
Public Scrutiny and Personal Identity
The theme of public scrutiny and personal identity is another crucial aspect of Holiday Hostilities. As a professional hockey player, Aaron Marino is no stranger to the public eye, but when a scandal involving his ex-fiancée Brandi is livestreamed, he becomes the subject of intense media scrutiny.
The situation forces Aaron to confront not only his public persona but also his private life, including his evolving relationship with Olivia. Olivia, on the other hand, finds herself thrust into the spotlight as well, especially when a private moment between her and Aaron is captured in a photograph and shared with the media.
This exposure forces both characters to reckon with how their relationship is viewed by others and how they want to define themselves in the eyes of the public. Aaron’s response to the media frenzy—standing firm in his commitment to Olivia and publicly declaring his love for her—marks a significant shift in his character.
He goes from being a reluctant playboy to a man who is unapologetic about his feelings and willing to defend his personal life against external pressures. Olivia, meanwhile, grapples with her own discomfort in being the center of attention, particularly when faced with judgment from Aaron’s ex-girlfriend and the broader public.
The theme of public scrutiny and personal identity highlights the tension between private desires and external expectations, as both Aaron and Olivia navigate the complexities of love under the watchful eyes of the media.
Holiday Traditions and Emotional Transformation
The holiday season in Holiday Hostilities serves as a backdrop to the emotional transformations of both Olivia and Aaron. For Olivia, the holidays represent a time of reflection, pain, and isolation due to her strained family relationships.
The contrast between her cold, distant memories of Christmas and Aaron’s warm family traditions, such as the Italian-American Seven Fish dinner, underscores the emotional divide between her past and the potential for a different future. As she spends more time with Aaron and his family, Olivia begins to experience the healing power of holiday traditions, which symbolize the possibility of new beginnings and emotional renewal.
Aaron, too, undergoes a transformation during the holidays, shifting from a man who avoids serious relationships to someone willing to publicly declare his love for Olivia. The holiday setting becomes a symbol of emotional growth for both characters, offering them a space to confront their pasts, embrace vulnerability, and build a future together.
The holiday traditions in the story serve not just as festive backdrops but as markers of personal change, illustrating how love, family, and connection can transform even the most difficult of experiences into opportunities for healing and emotional fulfillment.
