Guinevere Barrett is desperate to reach her grandmother's home before Christmas. She's lost her post and stolen a cat, and now she's missed the last stagecoach of her journey, leaving her stranded at an inn—until a handsome army officer offers to take her with him in his carriage.

Captain Adrian Fitzhugh is also rushing home, recalled from the front lines of the war in Spain to his dying grandfather's bedside. Taking up a poor governess is the last thing he needs, but Gwen makes him smile and laugh, and even though her cat makes him sneeze, he finds her more entrancing with every mile... just as a snowstorm descends to maroon them far from home with only each other, making them both wish their journey together could be just beginning.
