Wason authored 24 books after leaving CBS, mostly about one of her long time favorite hobbies, cooking, though her most successful book was her 1942 story of the Axis invasion of Greece,
Miracle in Hellas: The Greeks Fight On. She wrote that the book "was a resounding success. But the tough struggle to make it as a woman correspondent, ending with the cruel rebuff by CBS, cooled my desire for more overseas war reporting."
In 1998, at age 86, Wason wrote about macular degeneration, an affliction which stole most of her eyesight and rendered her legally blind.
Macular Degeneration: Living Positively with Vision Loss was written, in part, with a grant from the Washington State Department of Services for the Blind.
