An engineer awakens in a gilded Parisian nursery in 1811—reincarnated as Napoleon II, the young prince destined to live in his father's overwhelming shadow. Napoleon Bonaparte conquered empires and reshaped the continent, but his son inherited only confinement within royal walls, diplomatic scrutiny, and a historical fate of profound irrelevance. While the father became emperor, the son was written off as mere footnote. This reincarnated engineer, however, carries a crucial advantage: knowledge of the bleak historical trajectory awaiting him. But instead of accepting this predetermined path, he draws upon his modern expertise in history, politics, and science to forge an entirely different future. Positioned uniquely at the heart of Parisian power in 1811, he schemes to transform not just his own destiny, but the very course of European history itself. The son of the man who redrew the map of Europe now possesses something his father never could: foresight into tomorrow's mistakes. And he intends to change everything.
