The Bookworld’s leading enforcement officer, Thursday Next, has been forced into a semiretirement following an assassination attempt, returning home to Swindon and her family to recuperate. But Thursday's children have problems that demand she become a mother of invention: Friday’s career struggles in the ChronoGuard, where he is relegated to a might-have-been; Tuesday’s trouble perfecting the Anti-Smote shield, needed in time to thwart an angry Deity’s promise to wipe Swindon off the face of the earth; and the issue of Thursday’s third child, Jenny, who doesn’t exist except as a confusing and disturbing memory.
