"Ariel Pryce wakes up in Lisbon, alone. Her husband is gone--no warning, no note, not answering his phone. Something is wrong. She starts with hotel security, then the police, then the American embassy, at each confronting questions she can't fully answer: What exactly is John doing in Lisbon? Why would he drag her along on his business trip? Who would want to harm him? And why does Ariel know so little about her new--much younger--husband? The clock...

On a mission of revenge, and in the guise of English businessman Sebastian Foxx, exiled Sebastião Raposa returns to Lisbon, stalking the ruthless Inquisitor priest Pedro Azinheiro who imprisoned his parents ten years earlier. When a twist of fate turns his carefully laid plans to chaos, he will be forced to choose between surrendering to bloodlust or serving the cause of mercy.
