Vanessa Warner claims she’s living in fear. Stalked, threatened, and desperate for protection. But Nashville P.I.’s Ethan and Mickey Jenks quickly discover that nothing about Vanessa is simple. Her stories shift. Her enemies multiply. And the trail of bodies keeps growing.

Every new revelation drags them deeper into her shadowy world of secrets and lies. A world where charm is as dangerous as cruelty, and truth is buried beneath layers of manipulation. As lies collide with deadly truths, Ethan and Mickey realize they’re facing a woman who thrives on chaos—and whose immovable fixation is far more dangerous than anyone imagined.

When Mickey is attacked with the same switchblade tied to another investigator’s murder, the team begins to see the full scope of Vanessa’s lethal, all-consuming obsession. For Vanessa, fantasy and reality blur into a single, powerful delusion: Bowen Lynch, Ethan’s right-hand investigator. To her, he isn’t Bowen at all—he’s “Beau Weldon,” the man she insists was once hers, the man she vows to reclaim “for eternity.”

As Vanessa tightens her grip on her fantasy, Bowen becomes the unwilling centerpiece in a dangerous game where obsession twists into violence. And through it all, a white rose, and the haunting music and lyrics of Radio Company’s Sounds of Someday—the song she calls theirs—plays like a chilling soundtrack to her unraveling mind.

Obsession. Manipulation. Murder. For Vanessa Warner, someday isn’t a dream. It’s a promise. And fulfilling it will cost the life of anyone who stands in her way.
