Buffalo Valley: The town of Buffalo Valley, North Dakota--a community in farm country--is undergoing a revival. Vaughn Kyle, who's just out of the army, is looking for a place to live, a life to live. While he's waiting for his ambitious fiancee to make up her mind, he visits Buffalo Valley one snowy day and meets a young woman named Carrie Hendrickson. As they grow close, Vaughn has to question his feelings for the woman he thought he loved. He knows then that he wants to stay in Buffalo Valley, where life is about family and friends--not money and social standing. And not just at Christmas, but every day of the year...

Return to Promise: Rancher Cal Patterson and his wife, Jane--known as Dr. Texas--have recently separated, with Jane going back to her childhood home in California with their children. Now Cal, alone on his ranch, is forced to confront what he really wants in his life, what he needs. Jane is confronting the same questions. How seriously does Cal take his marriage vows? And how important is Promise to Jane? Is there hope for a reconciliation--in time for Christmas?
