An Invocation of Monsters by Cate Corvin is an intriguing entry in the realm of dark fantasy and supernatural genres, boldly mixing elements of horror, romance, and action into a narrative that's as beguiling as it is intense. The book is targeted at an adult audience, featuring mature themes and complicated relationships intertwined with a gripping plot that keeps readers on the edge of their seats. Cate Corvin, known for her ability to weave dark, mesmerizing tales, does not disappoint with this latest installment.

At its core, An Invocation of Monsters introduces us to a hauntingly vivid world where monsters roam not only in the shadows but also in the soul. The protagonist, Eris, is a compelling character with a complex heritage that makes her both a pariah and a pivotal figure in her universe. As the daughter of a notorious monster and a mortal, her life is nothing short of tumultuous. Eris's struggle with identity and power forms the backbone of the story, giving it both depth and a palpable tension that Corvin exploits expertly.

The story kicks off with Eris returning to her ancestral home after years of self-imposed exile, a place fraught with danger and old grudges. The reason for her return is layered — a mix of vengeance, the need to claim her rightful place, and the pursuit of understanding her monstrous lineage. The castle, a character in its own right, is described with chilling details that set the perfect backdrop for the narrative’s darker elements. Within these walls, Eris must navigate a labyrinth of old allies turned foes, new enemies masked as friends, and monsters that might be more humane than the humans around.

Corvin’s portrayal of the supernatural elements in the book is noteworthy. The monsters in Eris’s world are not merely creatures of the night but are embodiments of deeper fears and desires. They range from the grotesquely beautiful to the beautifully grotesque, each adding a layer of complexity to the narrative. The interactions between Eris and these creatures defy conventional norms; they are at once terrifying and tender, injecting a raw, emotional pull into the storyline that is rare in typical monster narratives.

The writing style of Corvin is rich and evocative, laden with metaphors and vivid imagery that paint the scenes in hues of dread and awe. Each chapter adds a new twist, keeping the readers guessing and turning pages with bated breath. The dialogue is sharp, often laced with a dark humor that fits well with the overarching theme of the book. Eris’s inner monologue, a critical element of the narrative, provides insight into her psyche, revealing her fears, her resilience, and her evolving thought process as she confronts her dark side and those who wish to exploit or destroy her.

One of the standout elements of the book is its exploration of themes such as identity, power, and the notion of what truly constitutes a monster. Is it the bloodline that defines a monster, or is it the actions one chooses? This philosophical question runs like a thread throughout the novel, woven into the conflicts and resolutions that push the plot forward. Eris’s journey is not just about survival but also about understanding and embracing her multifaceted nature, making her a protagonist that resonates well beyond the final page.

The romantic subplots in the book, though less prominent, provide a necessary counterbalance to its darker themes. The relationships Eris forms are fraught with challenges and steeped in complexities that mirror her internal and external conflicts. These relationships push her towards significant growth and realizations, adding layers to her character development that are as surprising as they are satisfying.

However, it’s important to note that An Invocation of Monsters is not for the faint of heart. The book delves into themes of violence, betrayal, and loss with a raw honesty that might unsettle some readers. The narrative’s strength lies in its unflinching exploration of the dark and the light, the human and the monster, making it a compelling read for those who appreciate depth, complexity, and authenticity in their fantasy novels.

In conclusion, Cate Corvin’s An Invocation of Monsters is a masterfully crafted tale that explores the depths of darkness and the complexity of human (and non-human) emotions. With its rich narrative, complex characters, and philosophical undertones, the book offers a fresh perspective on the monster genre and stands out as a poignant, powerful piece of literature. For fans of dark fantasy looking for a story that both challenges and entertains, this book is a must-read.
