Paul Loup Karl Sulitzer was a French financier and author. Before he turned seventeen, he was already a self-made millionaire. Sulitzer used his financial experience and knowledge in his books, which often related to the business world. Many of his books were ghost-written by Loup Durand.
Both Hannah and L’Imperatrice were amazing. Their portrayal of the lead character was subtle and powerful at the same time. It personally inspired me at a young age (I read them as a teenager) to always do my best in everything I embarked on.
