If you want his big-picture strategy book: The New Rules of War → Goliath
If you want a practical case study from the field: Building Better Armies

Sean McFate did not start out as the kind of writer people expect when they hear "war novelist." He spent part of his childhood in Ridgefield, Connecticut, then left for Saint Thomas Choir School in New York City, where music was a serious part of daily life. He has said he was a violinist first, and for a while imagined a future much closer to concert halls than battlefields.

Music came first.

At Brown University, he studied history and religious studies and went through ROTC. After college, he served as a paratrooper and officer in the U.S. Army's 82nd Airborne Division. He later described those years as the start of everything that followed. They took him into elite training programs, into real military command, and into the practical side of how power works when the stakes are life and death.

After the Army, McFate moved into the private military world, a shift that would define both his scholarship and his fiction. He worked as a contractor and political risk professional, spent years in Africa, dealt with warlords, rode with armed groups in the Sahara, and helped build Liberia's postwar army. That experience sits behind Building Better Armies and also behind much of the moral tension in his later novels. His work has always been close to the ground, not just theoretical.

He then went deep into academic study, earning degrees from Brown and the Harvard Kennedy School before completing a PhD in international relations at the London School of Economics. He has taught strategy at Georgetown University, Syracuse University, and the National Defense University, and he has also worked with policy institutions in Washington and Oxford. That mix, soldier, contractor, scholar, is what makes his books feel unusually lived-in.

McFate's nonfiction came first. In The Modern Mercenary, he explains how private armies fit into modern conflict and why they matter more than many governments want to admit. In The New Rules of War, and its UK edition Goliath, he argues that powerful states keep preparing for the wrong fights. Readers who like those books tend to come for the blunt, clear way he lays out big ideas: why technology does not solve everything, why deniable conflict matters, and why weaker actors often outplay stronger ones.

His move into fiction happened by accident. What became Shadow War started as a memoir, but he has said fiction gave him room to tell truths he could not easily put on the page in straight nonfiction. That book introduced Tom Locke, followed by Deep Black and High Treason, a mercenary protagonist shaped in part by McFate's own background. Readers usually come for the action, but stay for the mix of geopolitics, field detail, and hard questions about loyalty, money, and war.

He writes like someone who knows that strategy is personal.

McFate lives in Washington, DC, and still works at the intersection of ideas and real-world conflict. He teaches, comments on current wars, and keeps returning to the subjects that run through all his books: private power, hidden influence, and what people do when formal rules stop working. He has also kept up a long-running interest in opera and classical music, which feels fitting. His career has never moved in just one direction.
