Grace Livingston Hill 
Astra 

Astra Everson, traveling alone on a gloomy train, could only wonder about her uncertain future. Can she make a new life for herself in the home she once shared with her father? What will her meddlesome cousins do when they find she has fled their control to find independence?
Suddenly Astra is called upon to aid a mysterious stranger, and kind Charles Cameron enters her life. Together they face danger—and find love unfolding—as they experience the miracle of Christmas.
