The juxtaposition between the maternal love Cussy remembers while cuddling her pillow and the harsh reality of her life, where she faces a lot of hateful discrimination, highlights the challenges Cussy faces as a Blue. But it was her mother who taught her to read, too, and so the contrast reminds readers that books have the power to overcome discrimination and hatred and bring people together. Cussy Mary’s encounters with her patrons, who waited months for her return, show the power of books. Everyone is relieved and happy to see her, even patrons like Mr. Prine who are more stand-offish because of her blue skin.
