When Amy is rescued from the orphanage by Dr. Wallace to manage his practice, she is convinced God has heard her prayers, permitting her pursuit of medicine. And after serving as a civilian contract surgeon in the Civil War and then landing a job with the Union Pacific, she knows the Lord is guiding her goals.
