Master Key

The electrical fairy materialized in Rob's Chicago workshop on a winter evening in 1901, and everything changed. This wildly inventive predecessor to The Wizard of Oz imagines a world where electricity has unlocked the secrets of flight, invisibility, and distant seeing, technologies so advanced they border on magic. Young Rob, an curious inventor, is suddenly equipped with devices that would not seem out of place in a science fiction film: a flying chair, a stunning weapon, and a viewing screen that shows the world in real time. He travels the globe assisting kings and presidents, outwitting pirates and evil scientists, narrowly escaping disaster at every turn. The adventure crackles with Baum's characteristic ingenuity and optimism, a boy using cleverness and courage to reshape the world. The book carries the dated racial assumptions of its era, particularly in its portrayals of non-European peoples, elements that modern readers must approach with historical awareness.
