This historical novel will take you back to the late 1930s and the hill people of Kentucky as I learned about the blue people that lived in the area. Cussy Mary Carter believed to the last one alive. They were considered people of color. She is 19 and has WPA job carrying books and other information to the hill people. You feel for each one as they struggle to live. There is jealous, racial injustice and very little food. Making malnutrition a main cause of death. Cussy Mary’s father work in the coal mines of Kentucky. Roosevelt’s Kentucky Pack Horse Library Project is explained in full showing the value of books. I HIGHLY RECOMMEND THIS BOOK. Disclosure: Thanks to Sourcebooks/Landmark for a copy through NetGalley.
