Jass O'Reilly doesn't trust ex-agent Tarik Kadir. A bedouin from an ancient tribe, the dark and brooding Tarik isn't who the lovely CIA agent wants by her side as she tracks down rogue nuclear weapons. Besides, the mysterious sheik is just too handsome for an agent—the passion burning in his eyes a little too hot. Tarik knows Jass doesn't want him by her side as they delve deeper into the sultry Rio nightlife. Well, tough. But before the Carnivale is over, he will have to question everything he thought he knew about his mission, his job and his family. His own heart, he just might find, is the traitor.
