Erin Mackey's Obsession By Kaitlin is a gripping tale that delves into the complexities of desire, danger, and the dark corners of the human psyche. The book's premise, as outlined in its blurb, sets the stage for a thrilling narrative: one girl, three men vying for her affection, and a sinister stalker lurking in the shadows. This setup promises a rollercoaster of emotions and suspense, and Mackey delivers on that promise with a story that is as engaging as it is unsettling.

The protagonist, Abigail, is a character caught in a whirlwind of emotions and danger. Returning to her hometown after eight years, she finds herself entangled with her childhood friends, Ryan Masters and Parker Stevens, along with their enigmatic new companion, Colin O'Brian. The dynamics between these characters are central to the story, and Mackey does an admirable job of fleshing out their personalities and motivations. Abigail is portrayed as a strong yet vulnerable character, grappling with her own demons while being pursued by three men who each bring something different to the table.

Ryan, Parker, and Colin are depicted as the "kings of Eastgate," each with distinct traits that make them compelling in their own right. Ryan is the charismatic leader, Parker the brooding intellectual, and Colin the mysterious outsider. Mackey skillfully navigates the complexities of their relationships with Abigail, creating a tension that is both romantic and fraught with danger. The chemistry between Abigail and each of the men is palpable, adding layers to the narrative that keep the reader invested in their fates.

However, the story's true tension lies in the presence of the unknown stalker, whose chilling perspective is interspersed throughout the narrative. This character's obsession with Abigail adds a sinister edge to the story, heightening the sense of danger that permeates the book. Mackey's portrayal of the stalker is both disturbing and fascinating, offering a glimpse into a mind consumed by possessive love and a penchant for violence. The stalker's voice is haunting, and their threats loom large over the narrative, creating a sense of urgency that propels the story forward.

One of the book's strengths is its exploration of themes such as obsession, love, and the fine line between the two. Mackey delves into the psychology of her characters, examining what drives them to act as they do. Abigail's internal struggle with her feelings for the three men and her fear of the stalker is portrayed with nuance, making her a relatable and sympathetic character. The book raises questions about the nature of love and possession, challenging the reader to consider where the boundaries lie.

In terms of pacing, Obsession By Kaitlin maintains a steady rhythm, balancing moments of intense action with quieter, introspective scenes. Mackey's writing is vivid and evocative, painting a picture of a small town fraught with secrets and danger. The tension builds gradually, culminating in a climax that is both satisfying and thought-provoking. The resolution of the story ties up the various narrative threads, leaving the reader with a sense of closure while also pondering the implications of the characters' choices.

Comparatively, Mackey's work can be likened to other romantic thrillers that explore similar themes, such as Colleen Hoover's Verity or Penelope Douglas's Corrupt. Like these authors, Mackey excels at creating complex characters and intricate plots that keep readers on the edge of their seats. However, Obsession By Kaitlin stands out for its unique blend of romance and psychological suspense, offering a fresh take on the genre.

Overall, Obsession By Kaitlin is a compelling read that will appeal to fans of romantic thrillers and psychological dramas.
