Invasion: The Battle for Seoul: "Invasion turned him from outsider to Seoul's fiercest defender."

In the heart of a city he never expected to call home, former US Special Forces operator Jack Harper thought he had left war behind. But when North Korean forces, backed by Russia and Iran, launch a surprise attack on Seoul, Jack finds himself thrust into a conflict that will determine the fate of nations.

As missiles rain down and foreign troops flood the streets, Jack becomes the unlikely linchpin in a desperate resistance movement. Teaming up with Kim Joon-ho, a skilled South Korean Navy SEAL, Jack must navigate a treacherous landscape of urban warfare, international espionage, and shifting loyalties.
