Declared Hostile

A treasonous plot. Clandestine actors. World order hanging in the balance.

Elite NCIS investigator Emmy "Punky" King, seasoned in global espionage, uncovers the edges of an intricate international conspiracy following the arrest of a U.S. Marine. Relying solely on her sharp intuition, she starts peeling back layers of a complex mystery that links the U.S. president to a clandestine corporation. As she navigates the corruption, Punky finds herself deep in an escalating game that threatens more than just national security.

Halfway across the world in Eastern Europe, Colt Bancroft and the Black Ponies are thrust into a high-stakes mission to prevent nuclear weapons from falling into the hands of rogue Russian operatives. But when their operation spirals into chaos following an ambush by an unexpected adversary, Colt finds himself navigating the deadly terrain of enemy territory, fighting for survival.

Although separated by continents, their missions are fatally intertwined. Colt must battle against overwhelming odds while Punky races against time to uncover the traitor behind it all—both unaware that if either fails, the world will plunge into chaos.

From Jack Stewart, former US Navy Top Gun instructor pilot, comes Declared Hostile, the intense fourth installment in the acclaimed Battle Born series. This riveting narrative is a must-read for fans of Tom Clancy and Dale Brown, packing high-stakes action and intricate conspiracy into every chapter.
