Heart "Mac" MacKenzie is a tough police lieutenant in the rough streets of Brooklyn, New York. She's a strong leader who doesn't mind getting in the trenches with the men and women she leads at the seventy-four precinct. Her house, her people, and her family-both blue and blood-are the only things that matter. She would live and die for the blue wall that shields her from a traumatic past. When her captain assigns her a high-profile kidnapping case that she doesn't want, and insists she allows the missing girl's irritatingly sexy uncle to tag along during the investigation, her blood boils. Mac has no choice but to do what she always does when things get out of control, lay down the law-her law. Kenneth Searlington is a rich playboy from the Upper East Side of Manhattan. With stunning looks and an unlimited source of wealth, he's used to being the center of everyone's attention, especially the women that he comes in contact with. His life is fun and carefree until his niece, Merridith is kidnapped, and he's forced to seek out the help of his godfather an NYPD police captain, David Porter. Afraid and frustrated, Kenneth defers to his uncle's expertise and his promise that he's putting his best cop on the case, Lieutenant MacKenzie. When Kenneth discovers "Mac" is actually a sexy as sin lady cop with a fiery temper to match, he decides mixing a little business with pleasure might be just the thing he needs to distract him from long-standing family issues that are trying to crawl their way back into the forefront of his life. Each used to having their own way, can these two work together long enough to bring an innocent child home? Or will they settle their differences and unyielding attraction in a more carnal way and get right down to the heart of the matter?
