The protagonist in the story is Nell, a thete (or person without a tribe; equivalent to the lowest working class) living in the Leased Territories, a lowland slum belt on the artificial, diamondoid island of New Chusan, located offshore from the mouth of the Yangtze River, northwest of Shanghai. At the age of four, Nell receives a stolen copy of an interactive book, Young Lady's Illustrated Primer: a Propædeutic Enchiridion, in which is told the tale of Princess Nell and her various friends, kin, associates, &c., originally intended for the wealthy Neo-Victorian "Equity Lord" Chung-Sik Finkle-McGraw's granddaughter. The story follows Nell's development under the tutelage of the Primer, and to a lesser degree, the lives of Elizabeth and Fiona, girls who receive similar books. The Primer is intended to steer its reader intellectually toward a more interesting life, as defined by "Equity Lord" Alexander Chung-Sik Finkle-McGraw, and growing up to be an effective member of society. The most important quality to achieving an "interesting life" is deemed to be a subversive attitude towards the status quo. The Primer is designed to react to its owners' environment and teach them what they need to know to survive and develop.
