Mara Bennett only accepts the live-in nursing job because she desperately needs money for her younger brother’s cancer treatment. Her patient is Vincent DeLuca, one of Chicago’s most feared mafia bosses—a ruthless man left badly injured after an ambush and determined to drive away anyone who tries to help him. Six nurses have already quit. Mara becomes the seventh, but she refuses to be intimidated. As Vincent slowly begins to recover, Mara discovers that someone inside his own estate has been secretly keeping him weak. Worse, the danger soon reaches her brother. Trapped between betrayal, buried family secrets, and a growing attraction neither of them is willing to admit, Mara must decide how far she is willing to go to save a man who trusts no one. And Vincent must decide whether the woman who broke every rule he gave her might be the only person he can trust with his life—and his heart.
