In the glittering salons and shadowed corridors of Paris, Juliette Moreau is more than she seems. A courtesan by reputation, a spy by necessity, and a woman with a past buried so deep that even she dares not unearth it. But when a blood-red rose appears at the doorstep of the Saint-Clair estate—its petals a silent warning—Juliette knows that the past is no longer content to remain buried.

Gabriel de Saint-Clair is a man defined by restraint, by power wrapped in cold calculation. When his reckless younger brother is found dead at a masquerade, a rose clutched in his stiffening fingers, Gabriel has only one suspect—the woman who was last seen with him. But Juliette is no easy target, and as their paths intertwine, suspicion turns to something far more dangerous.

The rose is not merely a flower. It is a signature. A symbol of a past alliance, a warning of unfinished business, and a message from a ghost long thought dead. As Juliette and Gabriel chase the truth through the hidden underworld of Paris, secrets unravel—secrets that could bring down the most powerful families in the city, or consume them both in the process.

But trust is a blade with two edges, and as deception layers upon deception, one thing becomes clear:

The Blood Rose Pact was never meant to be broken.

And those who dare to try will pay in blood.
