No murder. Nothing underage. No sex without consent. Everything else is for sale aboard the Dionysia.

The most exclusive cruise ship in the world is a floating playground for the ultra-rich, where any fantasy has a price and the Concierge makes sure it's paid. Madalena Santos knows every guest's secrets. She grants every indulgence. And she guards the only three rules that can never be broken: no murder, no one underage, no one without consent.

Then a billionaire charters the whole ship to choose an heir, and packs it with his fractured family and his richest rivals. But Madalena is playing her own game. For thirteen years she's hunted the man who destroyed her. Tonight, she has reason to believe he's aboard.

Then a guest breaks the first rule.

The farther the Dionysia sails from shore, the clearer it becomes: this voyage was never about a will. Someone has been waiting for her. And the reckoning she's chased across half her life is coming early.

Luxury always has a price. Someone's about to pay it.
