Widower Luke Driskell didn't expect to fall in love and marry again so quickly. But Ashley and her daughter, Joy, are special--a quality borne out when Ashley rushes into a burning day-care center to save the children. Immediately she's a social media sensation and hero. Then, just as suddenly, Ashley and Joy disappear into the bitterly cold night.

With no trace of their whereabouts, Luke begins a panicked investigation. Alarmingly, he can find no proof that the woman he loves even exists. Left behind: just a hidden stash of fake IDs. Different names. Different cities. Same haunted face. Now the devastated husband has only questions: Who did he marry? What is she hiding?

Luke's cross-country pursuit of the truth soon spins into something more dangerous than he imagined. Because Ashley's secrets run so deep and dark that finding her could threaten all their lives.
