Mari Hernan's When Love Changes Everything is a compelling exploration of love, redemption, and the complexities of human relationships. The novel deftly navigates the intricate dynamics between Mateo, a self-proclaimed modern-day Casanova, and Lisa, his daughter's best friend, as they grapple with societal expectations, personal boundaries, and the transformative power of love.

At the heart of the story is Mateo, a character whose past is as colorful as it is tumultuous. Hernan crafts him as a deeply flawed yet inherently likable protagonist. His reputation as a chronic dater and a man with a past that rivals any soap opera sets the stage for a narrative filled with tension and potential for growth. Mateo's journey is one of self-discovery and redemption, as he confronts the ghosts of his past and the impact they have on his present and future.

Lisa, on the other hand, is portrayed as a beacon of intelligence and beauty, yet she is not without her own struggles. Her relationship with Mateo is fraught with the complications of being his daughter's best friend, adding layers of tension and forbidden allure to their interactions. Hernan skillfully develops Lisa's character, allowing her to evolve from a figure of temptation into a fully realized individual with her own desires and agency.

The chemistry between Mateo and Lisa is palpable from their first near-kiss on a hike, a moment that serves as a catalyst for the unfolding drama. Hernan captures the intensity of their attraction with vivid prose, making their connection feel both inevitable and fraught with potential consequences. The author does an excellent job of balancing the romantic tension with the emotional stakes, ensuring that readers are invested in the outcome of their relationship.

One of the novel's most compelling themes is the idea of redemption and the possibility of change. Mateo's journey is not just about finding love but also about confronting his past and making amends for his mistakes. Hernan explores the notion that love can be a transformative force, capable of healing old wounds and paving the way for a brighter future. This theme is underscored by the novel's title, which suggests that love has the power to change everything.

The subplot involving Mateo's daughter and her impending wedding adds another layer of complexity to the story. Hernan uses this narrative thread to explore themes of forgiveness and familial bonds, as Mateo grapples with the potential fallout of his relationship with Lisa. The tension between maintaining his daughter's trust and pursuing his own happiness creates a compelling internal conflict that drives the narrative forward.

Hernan's writing is both engaging and evocative, drawing readers into the world of her characters with ease. The dialogue is sharp and realistic, capturing the nuances of human interaction and the unspoken emotions that often lie beneath the surface. The pacing of the novel is well-executed, with moments of introspection balanced by scenes of high drama and romantic tension.

In comparison to other contemporary romance novels, When Love Changes Everything stands out for its mature exploration of complex themes and its focus on character development. While it shares some similarities with works by authors like Colleen Hoover and Nicholas Sparks, Hernan's novel distinguishes itself with its nuanced portrayal of flawed characters seeking redemption and the transformative power of love.

Overall, When Love Changes Everything is a beautifully crafted romance that delves into the intricacies of human relationships and the potential for personal growth. Mari Hernan has created a story that is both heartwarming and thought-provoking, offering readers a satisfying blend of romance, drama, and emotional depth.
