Mia Sheridan's Unnatural is a compelling blend of romance and suspense, weaving a narrative that is as emotionally charged as it is thrilling. The novel explores the depths of human connection and the resilience of the human spirit against a backdrop of mystery and intrigue. With its intricate plot and well-drawn characters, Unnatural is a testament to Sheridan's prowess as a storyteller.

At the heart of the novel is Autumn Sterling, a character whose life has been shaped by the haunting presence of a boy she was told never existed. Sheridan crafts Autumn with a deft hand, imbuing her with a complexity that makes her both relatable and intriguing. Autumn's journey from a haunted child to a nurse seeking purpose is a poignant exploration of healing and self-discovery. Her character is a study in contrasts—vulnerable yet strong, haunted yet hopeful. This duality is what makes her journey so compelling.

Sam, the enigmatic figure from Autumn's past, is equally well-developed. His reappearance in Autumn's life is the catalyst for the unraveling of a web of secrets and lies. Sheridan paints Sam as a man burdened by his past, yet driven by an innate sense of justice and love. His character is a fascinating blend of mystery and warmth, making him a perfect counterpart to Autumn. Together, they navigate a world filled with danger and deception, their bond growing stronger with each revelation.

The chemistry between Autumn and Sam is palpable, and Sheridan captures their connection with a sensitivity that is both tender and intense. Their relationship is the emotional core of the novel, providing a counterbalance to the suspenseful elements of the plot. Sheridan's ability to weave romance and suspense together is one of the novel's greatest strengths, creating a narrative that is both heart-pounding and heartwarming.

The themes of Unnatural are deeply resonant, exploring the nature of identity, memory, and the enduring power of love. Sheridan delves into the idea of how our past shapes us, and the courage it takes to confront the ghosts that haunt us. The novel also tackles the darker aspects of human nature, such as corruption and cruelty, with a keen eye for detail and a deep sense of empathy. These themes are woven seamlessly into the narrative, enriching the story and giving it a depth that elevates it beyond a simple romance or thriller.

In terms of plot, Unnatural is a masterclass in pacing and tension. Sheridan expertly balances the unfolding mystery with the development of Autumn and Sam's relationship, ensuring that the reader is constantly engaged. The twists and turns of the plot are well-executed, keeping the reader guessing until the very end. Sheridan's ability to maintain suspense while also delivering a satisfying emotional arc is a testament to her skill as a writer.

Comparatively, Unnatural shares thematic similarities with works like The Girl with All the Gifts by M.R. Carey, where the exploration of identity and the impact of scientific experimentation on human lives are central themes. However, Sheridan's focus on romance sets her work apart, providing a unique blend of genres that will appeal to a wide range of readers.

Overall, Unnatural is a captivating read that will resonate with fans of both romance and suspense. Sheridan's ability to create complex characters and weave them into a thrilling narrative is what makes this novel stand out.
