Just David - Eleanor H. Porter

David and his father set out from their idyllic mountain home to go to meet family, but enroute, David's father, who is sick dies, and David is left stranded in a little farming town. No one can read his father's handwriting, and David doesn't know his last name. A stern farmer and his wife take David in, and learn more from him than they realize! David, who counts only the sunny hours of his life, soon touches all the people's lives he meets in his new life with his beautiful violin music and sunny disposition. Written by Mary Anderson
