Eva Marks' Under the Bed is a gripping exploration of the dark recesses of the human psyche, a narrative that delves into themes of revenge, justice, and the complex interplay of love and obsession. The book's blurb sets the stage for a story that is as much about the monsters within us as it is about the literal ones that haunt our nightmares. Marks crafts a tale that is both chilling and compelling, drawing readers into a world where the lines between right and wrong blur, and where the protagonist's quest for vengeance becomes a journey of self-discovery.

The central character, whose name is not revealed in the blurb, is a fascinating study in contradictions. Described as a "freak in a mask" and a "cold-hearted psycho," he is a character who defies easy categorization. His self-awareness about his own monstrosity is both unsettling and intriguing, offering readers a glimpse into the mind of someone who is acutely aware of their own darkness. Yet, it is this very darkness that makes him a compelling character. He is not a villain in the traditional sense, but rather an anti-hero whose actions, while morally ambiguous, are driven by a deep-seated sense of justice.

Shiloh, the protagonist's stepsister, serves as a counterpoint to his darkness. Her kindness, sweetness, and innocence are highlighted as qualities that set her apart from the protagonist's world of shadows. She is the light to his darkness, the one person who sees beyond his monstrous exterior to the person within. This dynamic between the two characters is central to the narrative, providing a poignant exploration of how love and acceptance can exist even in the most unlikely of circumstances.

The theme of justice, or the lack thereof, is a driving force in the story. The protagonist's decision to take matters into his own hands after Shiloh is assaulted speaks to a deep-seated frustration with a system that has failed her. This act of vigilante justice is what ultimately lands him in a psychiatric hospital for eleven years, a punishment that underscores the societal perception of him as a monster. Yet, his time in the hospital does not diminish his resolve; rather, it strengthens his determination to seek revenge on those who wronged Shiloh.

Marks' portrayal of the protagonist's time in the psychiatric hospital is particularly noteworthy. It is a period of introspection and transformation, where the protagonist grapples with his identity and the consequences of his actions. The narrative does not shy away from exploring the complexities of mental health, offering a nuanced portrayal of a character who is both a product of his environment and his own choices.

Upon his release, the protagonist's quest for revenge takes center stage. This is where Marks' storytelling truly shines, as she weaves a tale that is both suspenseful and emotionally resonant. The protagonist's actions are driven by a fierce protectiveness over Shiloh, a desire to reclaim what he sees as rightfully his. This possessiveness, while unsettling, is portrayed with a depth that invites readers to question their own perceptions of love and ownership.

In terms of character development, Marks excels at creating multi-dimensional characters who defy easy categorization. The protagonist, in particular, is a character who evolves over the course of the narrative, his journey marked by moments of introspection and revelation. Shiloh, too, is a character who grows in complexity as the story unfolds, her innocence tempered by the harsh realities she faces.

Comparatively, Under the Bed shares thematic similarities with works like Gillian Flynn's Gone Girl and Stieg Larsson's The Girl with the Dragon Tattoo. Like Flynn and Larsson, Marks explores the darker aspects of human nature, crafting a narrative that is both thrilling and thought-provoking. However, Marks distinguishes herself with a focus on the psychological aspects of her characters, offering a more introspective take on the themes of justice and revenge.

Overall, Under the Bed is a masterful exploration of the human condition, a story that challenges readers to confront their own perceptions of right and wrong. Eva Marks has crafted a narrative that is both haunting and hopeful, a testament to the power of love and the resilience of the human spirit. For readers who enjoy psychological thrillers with complex characters and morally ambiguous themes, this book is a must-read.

While the book may not be for everyone, particularly those who prefer clear-cut heroes and villains, it is a rewarding read for those willing to delve into the gray areas of morality and human emotion. Marks' ability to craft a story that is both unsettling and deeply moving is a testament to her skill as a writer, making Under the Bed a standout addition to the genre.
