A cowgirl with a big heart. A single father with an autistic son. And a little boy who just wants Santa to bring him a mom for Christmas. Dianna Callahan is different than other people, but she never lets it get her down. She enjoys her horses, books, and family on their ranch in Copper Creek. When she agrees to help an autistic boy for Christmas, has she taken on more than she can handle? Tristan Wood brings his autistic son to the Equine Therapy Center in Copper Creek over Christmas. Maybe someone there can get 7-year-old Mathew to talk and act normally. Lord knows he’s tried everything else. Little Mathew Wood wants only one thing from Santa this Christmas—a mom. Maybe the pretty cowgirl helping him will make his wish come true. When Dianna and Tristan clash over how to help Mathew, will it result in broken hearts or a Christmas miracle?
