CIA paramilitary officer Danny Mercer has spent his career in the shadows, executing deniable missions as part of the Agency's elite Special Activities Division. But when the balance of global power begins to shift from Washington to Beijing, Mercer is drawn into a dangerous new conflict-one that pits him against enemies both foreign and domestic. Tasked with dismantling a covert alliance between the Black Orchestra-a secret network of U.S. intelligence and political elites-and a rogue Chinese faction led by the ambitious General Liu, Mercer is given access to The Langley Protocol, a cutting-edge AI system designed to defend democracy by taking the offensive. Armed with precise, lethal intelligence, Mercer begins targeting key operatives. But what begins as a surgical operation soon spirals into something far more complex. As international assassinations dominate headlines and global tensions reach a boiling point, Mercer realizes the most dangerous players aren't the ones on his target list-but the ones pulling strings from the shadows. From covert missions in Southeast Asia's narco-jungles to deadly ambushes in European capitals, and a power struggle brewing inside Beijing itself, Mercer is locked in a global chess match where every move could spark catastrophe. With support from MI6, DGSE, and allies of questionable loyalty, Mercer must navigate a world where betrayal is currency, and truth is buried beneath layers of deception. The Langley Protocol is a pulse-pounding espionage thriller that explores the thin line between national security and unchecked power-and what happens when one man is forced to confront both.
