Sarah Spade's Shannon in Sombra is a fascinating blend of urban fantasy and romance, weaving a tale that is both enchanting and thrilling. The narrative picks up years after the initial events that brought Shannon and Malphas together, diving headfirst into the complexities of their interdimensional family life. The book is a testament to Spade's ability to craft a world that is both fantastical and relatable, filled with rich characters and intriguing plotlines.

At the heart of the story is Shannon Crewes, a character who embodies resilience and determination. Her journey from a curious human who stumbled into the world of demons to a protective mother living in Sombra is both compelling and inspiring. Shannon's character development is one of the book's strongest aspects. She is portrayed as a fiercely independent woman who is willing to face any challenge to protect her family. Her transformation is not just about adapting to a new world but also about embracing her role as a mother and a partner to Malphas.

Malphas, the Sombra demon and Shannon's mate, is another well-crafted character. His relationship with Shannon is central to the narrative, providing a balance between the fantastical elements of the story and the emotional depth of their bond. Malphas is depicted as a complex character, torn between his duties in the demon world and his love for Shannon and their child. This internal conflict adds layers to his character, making him more than just a typical romantic hero.

The introduction of their child, a demon-human hybrid, adds a new dimension to the story. The prophecy surrounding the child's birth serves as a catalyst for the unfolding events, creating tension and urgency. This element of prophecy is a common trope in fantasy literature, but Spade manages to infuse it with fresh energy by focusing on the personal stakes for Shannon and Malphas. The prophecy is not just a plot device; it is intricately tied to the characters' development and the choices they must make.

Spade's world-building is another highlight of the book. The demon world of Sombra is vividly described, with its own rules, hierarchies, and challenges. The contrast between Shannon's human world and the demon realm is stark, yet Spade seamlessly blends the two, creating a setting that is both otherworldly and familiar. The presence of Duke Haures and the demon twins adds political intrigue and depth to the story, as Shannon navigates the complexities of demon society.

The themes of family, identity, and sacrifice are woven throughout the narrative. Shannon's struggle to protect her family while grappling with her identity as a human in a demon world is a central theme. Her journey is not just about physical survival but also about finding her place in a world that is vastly different from her own. The theme of sacrifice is also prominent, as Shannon and Malphas are forced to make difficult choices for the sake of their child and their future.

In comparison to other urban fantasy novels, Shannon in Sombra stands out for its focus on character development and emotional depth. While it shares similarities with works like Deborah Harkness's A Discovery of Witches or Patricia Briggs's Mercy Thompson series, Spade's novel is unique in its exploration of the intersection between human and demon worlds through the lens of family dynamics. The romance between Shannon and Malphas is central to the story, but it is the broader themes of love, loyalty, and identity that give the book its emotional resonance.

Overall, Shannon in Sombra is a captivating read that will appeal to fans of urban fantasy and romance alike. Sarah Spade has crafted a story that is both entertaining and thought-provoking, with characters that linger in the reader's mind long after the last page is turned. The book's blend of fantasy, romance, and family drama makes it a standout in the genre, offering a fresh take on familiar themes. Whether you're a longtime fan of Spade's work or new to her writing, Shannon in Sombra is a journey worth taking.
