There's a New Sin in Town — Tara Rose

HR director Vivian Tremaine spent ten years of her twelve-year marriage waiting for her ex-husband to be released from prison, only to have him ask her for a divorce. She finally gets together with Luke Henderson, her long-time friend next door, the same week she agrees to go out with Dr. Preston Benson, the new chief trauma surgeon at Sin Hospital that she hired. Luke's wife and infant son were killed by a drunk driver years ago, and he's been half in love with Vivian all his life. He waited too long after her divorce to ask her out, and now he might lose her to the new doc in town. Preston has a secret he hopes stays behind in Chicago. But Vivian knows it, and she goes out with him anyway. As he comes to realize if he wants her, he has to share her with Luke, his secret is uncovered and his job is threatened.
