Lauren Gilley's Golden Eagle, the fourth installment in the Sons of Rome series, is a compelling blend of historical fiction, supernatural intrigue, and emotional depth. This novel takes readers on a journey through time, from the icy landscapes of 1942 Siberia to the bustling streets of modern-day New York, weaving a narrative that is as much about personal discovery as it is about the supernatural elements that define its characters.

At the heart of Golden Eagle is the complex relationship between Nikita Baskin, a Chekist Captain turned vampire, and Sasha Kashnikov, a werewolf with a destiny intertwined with the infamous Rasputin. Gilley expertly crafts their bond, which is rooted in tragedy and trust, and explores the nuances of their connection with a tenderness that is both poignant and profound. The evolution of their relationship is a central theme, highlighting the struggle between duty and desire, protection and independence.

Gilley's portrayal of Sasha as an "unusually strong alpha wolf" who remains unbound is particularly noteworthy. This aspect of his character serves as a metaphor for the internal and external conflicts he faces. Sasha's struggle to define his identity and his place in the world is a reflection of the broader theme of self-discovery that permeates the novel. His desire to be more than just a "friend and little brother" to Nikita adds layers to his character, making him relatable and compelling.

The theme of found family is another significant element in Golden Eagle. The pack that Nikita and Sasha have formed in New York, which includes two detectives, an artist, and the former tsarevich of Russia, underscores the idea that family is not solely defined by blood but by the bonds we choose to create. This theme resonates throughout the narrative, providing a sense of hope and belonging amidst the chaos of the looming war.

Gilley's writing is both evocative and immersive, capturing the stark beauty of Siberia and the vibrant energy of New York with equal skill. Her ability to seamlessly blend historical events with supernatural elements is reminiscent of authors like Deborah Harkness and Anne Rice, yet Gilley maintains a unique voice that sets her apart. The historical backdrop of World War II adds depth to the story, grounding the fantastical elements in a reality that is both familiar and haunting.

Character development is a standout feature of Golden Eagle. Gilley delves deep into the psyches of her characters, exploring their fears, desires, and motivations with a deft hand. Nikita's journey is particularly compelling, as he grapples with his role as protector and his feelings for Sasha. The impending confession that has been "seventy-seven years in the making" adds an element of suspense and anticipation, keeping readers engaged and invested in the outcome.

The novel also introduces a host of intriguing secondary characters, each with their own stories and struggles. The inclusion of a Wallachian prince and the re-emergence of old enemies add layers of complexity to the narrative, expanding the scope of the story while maintaining a tight focus on the central themes of love, loyalty, and redemption.

In comparison to other works in the supernatural genre, Golden Eagle stands out for its emotional depth and character-driven narrative. While it shares similarities with series like The All Souls Trilogy by Deborah Harkness, Gilley's focus on the intricacies of human (and non-human) relationships gives her work a distinctive edge. The novel's exploration of themes such as guilt, honesty, and the courage to love without reservation adds a layer of introspection that is often missing in similar stories.

Overall, Golden Eagle is a captivating addition to the Sons of Rome series, offering a rich tapestry of history, fantasy, and emotion. Lauren Gilley has crafted a story that is both entertaining and thought-provoking, with characters that linger in the mind long after the final page is turned. For readers seeking a novel that combines the allure of the supernatural with the depth of human emotion, Golden Eagle is a must-read.
