Former Army Ranger Casey Weston had three rules he required all clients under his protection to follow: don’t go anywhere alone, do as he says, and don’t fall for him. Until Kate. She challenged his need for control the moment he stepped across the threshold of her Dallas townhome. One fateful night changed it all, when the cartel followed through on their threat and Casey took a life to save hers. If Casey makes Kate the exception to his rules, can he still protect her from the insistent threat, or will their growing attraction put more than his job on the line?
