This work investigates the historical evolution and dynastic survival of the Grimaldi family, the longest-reigning ruling house in the world. Anne Edwards, a biographer known for her studies of political and cinematic figures, utilizes a narrative approach to track the family's trajectory from its 12th-century origins to the modern era. The text prioritizes social dynamics, interpersonal relationships, and the internal scandals of the principality over rigorous economic or political analysis.

Critics note that while the work provides an accessible and engaging chronicle of the Grimaldi family, it often sacrifices historical depth for a focus on social intrigue and celebrity. The text is regarded as a popular history that serves as a readable introduction to the dynasty rather than a comprehensive academic study of Monaco's political evolution.
