Aspen Black's Crossing Between is a riveting foray into a world where magic is both a gift and a curse, and where the boundaries between life and death are blurred by the power of necromancy. The novel is a compelling blend of urban fantasy and mystery, with a strong emphasis on character development and thematic depth. It offers readers a gripping narrative that explores the complexities of identity, power, and the moral dilemmas that arise when one's very existence is deemed illegal.

At the heart of the story is Zoey Halinger, a character whose life is defined by secrecy and survival. Zoey's journey is one of self-discovery and empowerment, as she grapples with her identity as a necromancer in a society that criminalizes her abilities. Her character is richly developed, with Aspen Black skillfully portraying her internal struggles and the external pressures she faces. Zoey's evolution from a woman hiding her true self to one who embraces her power is both inspiring and relatable, making her a protagonist that readers can root for.

The novel's setting—a city teetering on the edge of chaos due to a series of magical murders—provides a tense and atmospheric backdrop for the unfolding drama. Black's world-building is meticulous, with the supernatural elements seamlessly integrated into the fabric of the city. The author paints a vivid picture of a society where magic is both feared and revered, and where the lines between good and evil are often blurred. This nuanced portrayal of a magical world adds depth to the narrative, inviting readers to ponder the ethical implications of power and control.

One of the standout aspects of Crossing Between is its exploration of the theme of identity. Zoey's struggle to reconcile her public persona as a licensed Medium with her true nature as a necromancer is a powerful commentary on the masks we wear to fit into society. The novel delves into the idea that true strength lies in embracing one's authentic self, even in the face of societal condemnation. This theme is further reinforced by the diverse cast of characters who surround Zoey, each grappling with their own identities and loyalties.

The relationships Zoey forms with the three men who become entangled in her life add an intriguing layer to the narrative. Each of these characters— the vampire boss, the kraken healer, and the oni detective—brings a unique dynamic to the story. Their interactions with Zoey are complex and multifaceted, highlighting themes of trust, loyalty, and the blurred lines between ally and adversary. These relationships are not just romantic or platonic; they are deeply intertwined with the central mystery and Zoey's personal growth.

Black's writing is both evocative and engaging, with a keen eye for detail and a talent for crafting suspenseful scenes. The pacing of the novel is well-balanced, with moments of intense action interspersed with quieter, introspective passages. This rhythm keeps readers on the edge of their seats while allowing for deeper exploration of the characters' inner worlds. The dialogue is sharp and often laced with wit, adding a layer of realism to the interactions between characters.

In terms of its overall impact, Crossing Between is a thought-provoking and emotionally resonant read. It challenges readers to consider the nature of power and the consequences of its misuse, while also offering a hopeful message about the strength found in self-acceptance. The novel's conclusion is both satisfying and open-ended, leaving room for further exploration of Zoey's world and the mysteries that inhabit it.

For fans of urban fantasy, Crossing Between will likely draw comparisons to works by authors such as Ilona Andrews and Patricia Briggs, who also excel in creating richly detailed magical worlds with strong, complex protagonists. However, Aspen Black's novel stands out for its unique take on necromancy and its focus on the moral complexities of wielding such power.

In conclusion, Crossing Between is a masterful blend of fantasy and mystery, with a compelling protagonist and a richly imagined world. Aspen Black has crafted a story that is both entertaining and thought-provoking, making it a must-read for fans of the genre. Whether you're drawn to tales of magic, mystery, or personal transformation, this novel offers something for everyone, leaving a lasting impression long after the final page is turned.
