In the shadows of Blackwood Estates, the truth is as viscous as the blood on the marble floor. Clara Vance is a masterpiece of high-society perfection, but her life is a carefully constructed cage. When she finds her husband, Julian, dead at the base of their grand staircase, the twenty-minute gap in her memory becomes a countdown to her ruin. The police see a grieving widow, but a single, fresh cherry-red lollipop left at the scene points to a history Clara has spent years burying. As a hidden conspiracy known as Project Mercury begins to breathe through the vents of her home, Clara realizes she isn't just a suspect—she's a prototype. In a world of silver echoes and fractured identities, Clara must decide: is she the victim of a global game, or the one who made the final move? If you can't trust your own memory, how do you know you aren't the monster you're running from?
