The town of Promise, Texas, is a good place to live, to raise a family, to spend the rest of your days with the person you love.

Cal Patterson and his wife, Jane--also known as Dr. Texas--certainly think so. The last thing they expect is a threat to their marriage. But in September, disagreements begin to escalate--with the "help" of an attractive young woman who's got her eye on Cal.

After months of emotional upheaval brought on by doubts about their marriage, the two separate, and Jane returns to her childhood home in California, taking their children. Cal, now 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?
