Emma Carter has spent three years trying to prove that her missing brother did not murder Angela Romano, the late wife of New York crime boss Don Romano. When Emma spots a rifle aimed at Don during a charity gala, she tackles him and locks down his mansion—trapping the assassin inside with two hundred guests. The evidence left behind carries her brother’s name, forcing Emma into a dangerous alliance with the man who once hunted him. But Don has concealed a betrayal of his own: he hired Emma hoping she would draw her brother out of hiding. As Angela’s silent daughter begins revealing what she witnessed before her mother’s death, Emma and Don uncover a trafficking network operating beneath the Romano family’s legitimate empire. Someone has stolen Don’s command code, turned his own men against him, and marked his daughter as the next target. To save the child and expose the truth, Emma must decide whether she can trust a ruthless man learning to surrender control—and Don must choose between protecting his empire and becoming worthy of the woman who refuses to belong to him.
