Shadow of the Underground: An Empire of Lies: a psychological fiction novel published in late 2025 about an "invisible kingdom" of power, corruption, and manipulation beneath Paris. It is the third book in the Crowns of the Shadow series.

The story focuses on Stephen DuPont, the youngest of the lost triplets in the powerful DuPont dynasty. After his father's empire collapses, Stephen builds a new, invisible empire in the Parisian underground, ruling through blackmail and contraband. He is a master of manipulation, playing the elite against each other.

The plot intensifies when a precision leak threatens to expose crimes the family buried decades ago. Old enemies, including Russian cyber-blackmail queen Zoya Malkova and Triad mastermind Liu Xian, return, forcing Stephen to navigate dangerous alliances and internal betrayal. He follows a trail into the "Ghost Crown Network," a secret and deadly syndicate, all while deciding who to destroy, protect, and what the value of his soul is.
