The woman he could never forget... The killer he never knew existed... Artist Gwen Trueblood is shocked to discover her husband David's accidental death was actually premeditated murder. Almost as troubling is the revelation that he was in the Witness Protection Program, making Gwen question how well she knew her husband at all. Only one person can give her the information she needs, but he's the very last person on earth Gwen wants to speak to. U.S. Marshal Colin Mitchell was like a brother to David Beaumont when they were growing up, until Colin realized he and his friend's fiancé shared an almost cosmic connection. When Gwen has a spicy daydream and Colin experiences it right along with her, it's too much for him to resist. He makes a move that ultimately costs him both the woman he loves and his relationship with David. Colin was in charge of the investigation into David's death, and he can't believe he let the other man's killer get away. The case is reopened, bringing David's murderer out of hiding and putting Colin and Gwen directly in the path of evil itself. Together they must discover the truth of what happened to David, as they struggle to come to terms with the passionate attraction that's been smoldering between them since the fateful daydream years before.
