Not Bad for a Girl by Anastasia Ryan is a compelling narrative that challenges traditional norms and explores the depths of fighting against predefined gender roles. Ryan’s debut novel in what promises to be an intriguing series, centers around a protagonist, Mia, who defies every stereotype with her gritty determination and undying passion for football, a field dominated by males.

Mia Hamilton's journey begins in a small town where her dreams seem larger than life and the obstacles insurmountable. Raised in a conservative family, Mia’s passion for football is frowned upon, viewed merely as an unconventional and fleeting hobby. Ryan beautifully captures Mia's internal struggles and the dynamics of a community where such aspirations can lead to conflict and isolation. The author’s portrayal of Mia not merely as a gifted athlete but also as a multifaceted character dealing with typical teenage issues—like friendships, family dynamics, and first loves—adds a rich layer of authenticity to the narrative.

The strength of the novel lies in its well-rounded characters and the palpable tension between traditional expectations and personal aspirations. Ryan’s prose is crisp and vibrant, bringing to life the dusty football fields and the charged atmosphere of high school competitions. One of the most powerful elements of Ryan's writing is her dialogue. Conversations between Mia and her peers, her coaches, and her overbearing but loving family, flow naturally, each one building on and peeling back layers of each character’s motivations and fears.

Another remarkable aspect of Not Bad for a Girl is the way it addresses sexism in sports. The narrative doesn’t shy away from the harsh realities of what it is like to be a girl in a male-dominated sport. Mia’s encounters with gender bias are depicted in a raw and straightforward manner, making her victories all the more triumphant and her setbacks deeply frustrating. These moments are poignant reminders of the societal hurdles women face, not just in sports but in many ambitious pursuits.

Supporting characters in the novel also deserve a mention. From Mia’s staunchly traditional yet subtly supportive father to her exuberant and spirited teammates who bring levity and support to Mia’s intense journey, each adds depth to the story. Particularly notable is the character of Joey, Mia’s younger brother, who adores his sister and inadvertently offers a contrasting perspective on gender roles within the same household.

The thematic richness of the book covers more than just gender issues; it delves into the importance of community, resilience, and the power of change. It is a balanced weave of motivational moments and realistic setbacks. Ryan also sensitively handles the aspect of mental toughness and the psychological battles athletes face. Through Mia’s eyes, we see the pressure of constantly proving oneself, the mental fatigue, and the sheer joy of playing the sport she loves.

However, while Not Bad for a Girl handles many elements well, it occasionally suffers from pacing issues. Certain parts, especially in the middle of the book, feel slightly drawn out. Some of Mia’s introspective moments, although insightful, slow down the momentum built by the thrilling game sequences and interpersonal drama.

The climax of the novel is both heart-wrenching and uplifting, as it should be. Mia’s final game of the season is a cathartic culmination of her emotional and physical journey. Ryan’s description of this pivotal match is nothing short of cinematic, plunging the reader directly into each moment of tension and elation. It’s here that Mia truly comes into her own, embodying not just the skills of a star athlete but the indomitable spirit of someone who challenges and changes the status quo.

In conclusion, Not Bad for a Girl is not just a story about a girl playing football; it’s a robust exploration of ambition, identity, and the challenges of breaking barriers. Anastasia Ryan handles both the sport and her protagonist with the respect and depth they deserve, making her debut not just promising but profoundly impactful. This book is a clarion call for all young girls with seemingly unreachable dreams to keep striving and, equally, a reminder for society to reexamine and support such aspirations without bias. Readers who enjoy strong female protagonists, sports narratives, and stories of personal growth will find plenty to love in Anastasia Ryan’s compelling tale.
