Gerard de Marigny

Gerard de Marigny is an Amazon bestselling author and the creator of the Cris De Niro series—high-stakes techno-thrillers that blend global conflict, intelligence warfare, and deeply personal consequences.

His novels explore a world where the next war doesn’t begin on a battlefield, but in the shadows—through covert operations, political deception, and unseen enemies already in motion.

At the center of the series is Cris De Niro, a man forced into action when the systems designed to protect us fail—again and again.

de Marigny’s work is driven by a passion for cinematic storytelling that combines grounded realism with relentless tension, drawing readers into stories where every decision carries weight and every mistake has consequences.

From The Watchman of Ephraim to Signs of War and beyond, the Cris De Niro series unfolds as an escalating narrative of modern conflict.

He is also the author of Joshua’s Country, a modern war western, and is currently developing the epic faith-based fantasy series The Nazir.

In addition to his novels, de Marigny writes for film and television with his producing partner Michael Greenburg (MacGyver, Stargate SG-1, among others).
