Claire Highton-Stevenson's The Last to Know is a compelling exploration of friendship, love, and the complexities of human relationships. At its core, this novel delves into the intricate dynamics between two best friends, Grace Hart and Caz Madden, who find themselves navigating the blurred lines between platonic friendship and romantic love. The narrative is a heartfelt journey that challenges societal norms and personal boundaries, making it a thought-provoking read for anyone interested in the nuances of human connection.

The story begins with Grace Hart, a woman in her late 30s, who is grappling with the ticking clock of her biological timeline. Her desire for a child and a family of her own is palpable, and Highton-Stevenson does an excellent job of portraying Grace's internal struggle. Grace's decision to turn to her best friend, Caz, as a potential partner in this endeavor is both bold and unconventional. This decision sets the stage for a narrative that is as much about self-discovery as it is about love.

Caz Madden, on the other hand, is a character who embodies the complexities of unspoken desires and hidden emotions. As a lesbian, Caz's attraction to her straight best friend adds a layer of tension and depth to the story. The author skillfully portrays Caz's internal conflict, making her a relatable and sympathetic character. The emotional intimacy and trust that Caz and Grace share are beautifully depicted, and their evolving relationship is both tender and realistic.

One of the standout themes in The Last to Know is the exploration of identity and the fluidity of sexual orientation. Highton-Stevenson challenges the traditional labels of "straight" and "lesbian" by presenting a narrative where love transcends these boundaries. The novel invites readers to question the rigidity of these labels and consider the possibility that love can exist in many forms. This theme is particularly relevant in today's society, where discussions about gender and sexual identity are becoming increasingly prominent.

The character development in this novel is exceptional. Both Grace and Caz are multi-dimensional characters with their own fears, desires, and insecurities. As the story unfolds, readers witness their growth and transformation. Grace's journey from a woman desperate for a family to someone who embraces the unexpected path her life takes is both inspiring and relatable. Similarly, Caz's struggle with her feelings for Grace and her fear of losing their friendship adds depth to her character and makes her journey all the more poignant.

Highton-Stevenson's writing style is both engaging and evocative. Her ability to capture the subtleties of human emotion is evident throughout the novel. The dialogue between Grace and Caz is natural and authentic, and the chemistry between them is palpable. The author also does an excellent job of creating a sense of place, with vivid descriptions that bring the settings to life.

In terms of pacing, The Last to Know strikes a perfect balance between introspective moments and plot development. The narrative unfolds at a steady pace, allowing readers to fully immerse themselves in the characters' journeys. The tension between Grace and Caz builds gradually, culminating in a satisfying and emotionally resonant climax.

Comparatively, The Last to Know shares thematic similarities with other works that explore the complexities of friendship and love, such as Red, White & Royal Blue by Casey McQuiston and One Last Stop by the same author. However, Highton-Stevenson's novel stands out for its focus on the fluidity of sexual orientation and its nuanced portrayal of a friendship that evolves into something more. The novel's exploration of these themes is both refreshing and thought-provoking, making it a standout in the genre.

Overall, The Last to Know is a beautifully written and emotionally resonant novel that will appeal to readers who enjoy stories about love, friendship, and self-discovery. Claire Highton-Stevenson has crafted a narrative that is both heartwarming and thought-provoking, with characters that will stay with readers long after they turn the final page. Whether you're a fan of romance or simply enjoy stories that explore the complexities of human relationships, this novel is a must-read.
