 "The Encyclopædia Britannica" describes her as a "Canadian poet who revealed the progress of an interior spiritual journey in her three successive volumes of poetry," referring to her first three books, "Winter Sun", "The Dumbfounding", and "sunblue".With "Winter Sun", "Avison established herself as a difficult and introspective poet given to private images and subtle shadings of emotion that challenge and frustrate the reader" (says "The Canadian Encyclopedia)".
