Cristabelle Shannon is struggling to support her ailing mother as a laundress at Fort Clark. Pious and serious, Crissy safeguards a family secret. If her secret gets out, she could lose her position, the only decent job she can find. Crissy dreams of a day when she can put her shameful secret behind—a place where no man can trouble her.

Sergeant David Donovan is a fun-loving prankster, who has made the United States cavalry his home. He joined the Army for adventure and to guard the frontier. His outlandish jokes have cost him his stripes, several times, only to be won back by his bravery. Davie is an Army lifer, committed to his free-wheeling ways and with no thought of settling down.

When Davie meets Crissy, he’s drawn to her. The rules of the fort’s commander forbid their relationship. Not wanting to lose her job or encourage him, Crissy resists Davie’s attentions. But when he discovers a plot to steal the fort’s payroll and is plunged into danger, Crissy realizes how much she cares for him. Can she face the shameful secret in her past to embrace her future and be Davie’s Christmas bride?
