It's set to be a white Christmas in Hart County, and Grace King is pet-sitting in a beautiful home with only a difficult dachshund for company. Just as she starts to miss the bustle of her large Amish family, Grace runs into a familiar face. Living right next door is John Michael Miller. He's a fireman now, but five years ago, he had courted her older sister, then broke her heart. Seeing him again stirs Grace's anger, but also reminds her of deeper feelings she's done her best to deny.
