When CIA operative Lena Vasquez boards a luxury cruise through the Strait of Hormuz to extract a defecting Iranian general, she never expects the ship to become a floating prison. A deadly hantavirus outbreak locks down the vessel while an arms cartel—led by the most ruthless mafia don in the Persian Gulf—hunts the general for the launch codes tattooed on his body. Trapped between a biological nightmare and cold-blooded killers, Lena must forge an impossible alliance with Dominic Ferretti, the exiled Italian mafioso she was sent to assassinate. In a world where governments lie, viruses mutate, and loyalty is worth less than the bullets in your chamber, the only currency that matters is survival. And Ferretti always collects his debts.
