He's a ruthless guardian devoted to a life without personal entanglements. She’s a feisty Scottish heiress suffering vicious threats to her life. Forced together, the fiery attraction between them could be their undoing, or their true salvation. One small abduction and her world falls apart. Nemity Wheldon was abducted, yes, but she got away. Unharmed. It certainly doesn’t warrant hiring a guard looking to stifle her every move. Alas, her overbearing cousin demands it, delivering Callum to her door. He’s a guard. A big, burly, stubborn one. An unnervingly handsome man, yes, but the last thing she needs is him digging into her life. There are only two routes to take in this situation—annoy him or avoid him—whichever will make him quit the job. A guardian to his bones. Callum Lonstrick has never quit a mission, and he isn’t about to start with one headstrong spinster. He’s been a guardian for far too long—more than half of his life. And he isn’t about to let a feisty Scottish heiress best him. He’s there to protect her, and that’s exactly what he’s going to do. Never mind that he’s instantly attracted to the maddening hoyden that is determined to vex him at every turn—one never touches a client. Forced together, a game of cat and mouse is afoot. Nemity doesn’t want him to discover any of her secrets, while Callum is determined to unravel each and every one, for it is the only way to properly protect her. Yet with each secret he discovers, the danger only grows. Save her? That’s a given—he’s a guardian, after all. Save his heart? That may just be an insurmountable feat.
