Desirée M. Niccoli's Untethering Dark is a captivating foray into the realm of monster romance, a subgenre that has been gaining traction for its ability to blend the fantastical with the deeply personal. Set against the haunting backdrop of the Black Forest, this novel weaves a tale that is as enchanting as it is unsettling, drawing readers into a world where magic, desire, and danger coexist in a delicate balance.

The protagonist, Astrid, is a winter hag in training, a character whose complexity is immediately apparent. Her life in the Black Forest is one of duality—by day, she hones her magical skills and wards off unwelcome tourists with her axe-throwing prowess; by night, she performs rituals to appease the ancient monster that guards the woods. Astrid's journey is one of self-discovery and transformation, as she stands on the precipice of leaving her humanity behind to embrace her full magical potential. This internal conflict is a central theme of the novel, exploring the tension between human vulnerability and supernatural power.

Niccoli's portrayal of Astrid is both nuanced and compelling. She is not your typical heroine; her strength lies not only in her magical abilities but also in her willingness to confront her fears and desires. Her relationship with Gudariks, the eldritch monster of the forest, is the heart of the story. Gudariks, who has existed since the forest's inception, is a character shrouded in mystery and menace. Yet, beneath his fearsome exterior lies a depth of emotion that Niccoli skillfully unveils as the narrative progresses.

The dynamic between Astrid and Gudariks is a fascinating exploration of the monster romance trope. Unlike many stories in this genre where the monster is tamed or humanized, Niccoli allows Gudariks to retain his otherworldly essence. Their relationship is not about taming the beast but about understanding and embracing the darkness within each other. This is a refreshing take that challenges conventional narratives and invites readers to reconsider the nature of love and acceptance.

As Astrid and Gudariks grow closer, the novel delves into themes of desire and identity. The intimacy they share is both physical and emotional, a union that transcends the boundaries of their respective worlds. Niccoli's writing is evocative, capturing the sensuality and intensity of their connection without resorting to clichés. The sex ritual that Astrid must perform to complete her transformation is a pivotal moment in the story, symbolizing her willingness to embrace her true self and the power that comes with it.

However, Untethering Dark is not just a romance; it is also a tale of suspense and intrigue. The introduction of a rising supernatural threat adds a layer of urgency to the narrative, forcing Astrid and Gudariks to confront their vulnerabilities and question their ability to protect the forest. This external conflict mirrors their internal struggles, creating a rich tapestry of tension and drama that keeps readers engaged.

Niccoli's world-building is another standout aspect of the novel. The Black Forest is more than just a setting; it is a living, breathing entity that influences the characters and the plot. The forest's ancient magic is palpable, its mysteries and dangers lurking at every turn. Niccoli's descriptive prose brings the forest to life, immersing readers in its eerie beauty and foreboding atmosphere.

In comparison to other works in the monster romance genre, such as Sarah J. Maas's A Court of Thorns and Roses or Silvia Moreno-Garcia's Mexican Gothic, Untethering Dark stands out for its bold exploration of the darker aspects of love and power. While Maas and Moreno-Garcia also delve into the complexities of human-monster relationships, Niccoli's novel is distinguished by its willingness to embrace the monstrous without compromise. This makes for a more authentic and resonant reading experience, one that challenges readers to confront their own perceptions of beauty and monstrosity.

Overall, Untethering Dark is a masterful blend of romance, fantasy, and suspense. Niccoli's ability to craft complex characters and a richly detailed world results in a story that is both thought-provoking and deeply satisfying. For readers seeking a novel that pushes the boundaries of the monster romance genre, Untethering Dark is a must-read. It is a testament to the power of storytelling to illuminate the shadows within us all, inviting us to embrace the darkness and find beauty in the unknown.
