Tell Me Your Desires by Melissa Tereze

When the line between pain and pleasure blurs, everyone bleeds.

Detective Jaime Baros claws her way through each night, haunted by the blood-soaked memory of her fiancée’s brutal murder. Three years of insomnia haven’t dulled the pain. Now a sadistic killer carves a path through the city, forcing Jaime to plunge into the abyss she’s fought desperately to avoid. The investigation slams her against Lady A, a dominatrix whose
razor-sharp gaze ignites a hunger Jaime believed died with her fiancée. As Lady A’s world consumes her, Jaime can’t distinguish between predator and prey.
Beneath Lady A’s iron control writhes Anastasia Grant, a woman shattered by betrayal four years ago. She exists in shadows with her cat Derek—until her clients begin appearing in morgues and a devastatingly magnetic detective crashes through her carefully constructed walls.

With death circling closer, Jaime and Anya must rip open old wounds and surrender to their most terrifying desires or become the killer’s next masterpiece.
