As the time draws near for the twice-yearly cattle drive, Mr. Carson is feeling his age. He wants to be there when his grandkids - all nine of them - experience the magic and the history of the drive for the first time. Emma Carson enlists her best friend to come from Houston to help wrangle the kids while their parents wrangle the herd.
But from the moment Dee steps off the bus and comes face to face with a vision from her dark past, trouble begins. Can she and Hawk patch up their differences long enough to save the kids from revenge gone wrong, and is the past ever truly behind them?
