Diovanni Carelli almost lost his life on a mission gone to hell in Afghanistan. Home after an exhausting year of learning to talk, walk and stand up straight, he moves to a nice quiet neighborhood with his war dog, Caliber, and settles into normal civilian life as a securities expert, putting his Navy SEAL training to use. His new job is to protect Senator Donald Penn, a less than honorable man, whose high profile friends are being assassinated. There isn't much that surprises Dio. Except for his sexy new neighbor that comes home at all hours wearing outlandish outfits and carrying a black duffle bag.Layne Thomas is not completely unmoved by her neighbor's dark looks and piercing blue eyes. The better part of her would love to get to know him, however her past dictates that she can't get involved, for her safety and Dio's. Her career isn't leaving much room for a quiet life without chaos. Against her better judgment, she and Dio come to an arrangement; four steamy days and nights of no strings attached fun.Layne and Dio burn up the sheets, but when Senator Penn gets shot at an event that Diovanni was hired to do, pieces start falling into place. Like the shooter being a woman and looking very much like a blond with a body that won't quit. Someone he recognizes intimately.Dio wants to break down Layne's carefully constructed walls, walls he has no problem blasting apart, but could Layne be the one picking off unscrupulous CEOs and Senators? The hits feel personal and the thought of anyone turning his seemingly caring, sweet neighbor into a murderer, has him reevaluating his life and what he thought he was willing to do in the name of honor.
