Rhiannon Beaubien is an author and former intelligence professional whose work spans decision-making nonfiction and Cold War espionage fiction. She co-authored The Great Mental Models series with Shane Parrish, including Volume 1, a Wall Street Journal bestseller, and wrote the spy novels Alone Among Spies, The Wrong Kind of Spy, and A Rumor of Spies.
Rhiannon Beaubien is a Canadian writer whose career bridges intelligence work, editorial strategy, and fiction. Educated in Toronto before studying philosophy and drama at Queen’s University and later international communications at the University of Leeds, she developed an early habit of combining argument, structure, and imagination. She then spent more than a decade at a Canadian intelligence agency, an experience that became the decisive turning point in her writing life. The move from classified work to public authorship gave her both subject matter and a durable interest in systems, incentives, and human behavior.
