When renowned interior designer Vivienne Hartwell receives an invitation to showcase her latest tiny cottage designs at the prestigious Tiny Cottage Expo, she expects nothing more than a weekend of networking and admiration. But when the expo's star attraction—a revolutionary $200,000 tiny cottage dubbed "Dreams in Miniature"—becomes the scene of a brutal murder, Vivienne finds herself trapped in a nightmare that threatens to destroy everything she's built.

The victim is Marcus Wellington, a charismatic entrepreneur whose company was set to revolutionize the tiny home industry. His body is discovered in the expo's most anticipated display, surrounded by Vivienne's own furniture designs and blueprints for her dream project. As local detective Ray Torres begins his investigation, he quickly realizes that nearly everyone at the expo had motive and opportunity—from bitter business rivals to scorned lovers, from jealous competitors to desperate clients.

Set against the backdrop of the charming but cutthroat world of tiny home design, where every inch matters and every detail reveals a secret, Vivienne must navigate a maze of lies, betrayals, and hidden agendas. The expo grounds become a pressure cooker of tension as personal dramas unfold in the cramped quarters of tiny living spaces, where privacy is a luxury and secrets have nowhere to hide. Each contestant's tiny home becomes a window into their soul—and their potential for murder.

As Vivienne delves deeper into the investigation, she discovers that Marcus was not the innovator everyone believed him to be. His revolutionary designs were stolen, his business built on deception, and his personal life a web of carefully constructed lies. But when another body turns up in the expo's demonstration kitchen, it becomes clear that someone will kill to keep their secrets buried beneath the veneer of perfect tiny living.

With her reputation on the line and her business partner under suspicion, Vivienne must use her expertise in spatial design and attention to detail to uncover the truth before the killer strikes again. Every blueprint tells a story, every measurement reveals an intention, and every tiny space holds a clue that could mean the difference between justice and another unsolved murder. But as she gets closer to the truth, she realizes that the killer's next target might be closer than she thinks—because in the world of tiny homes, there's nowhere to run, and nowhere to hide.

Can Vivienne solve the murder before the expo ends and the killer disappears into the crowd, or will she become the next victim of someone who believes that some dreams are worth killing for?
