Humanity thought it was divided. The truth is far worse.

As the United Alliance and Coalition Forces set aside decades of hostility to face a ruthless alien enemy, a devastating secret comes to light—the invaders aren't acting alone. They've been using humans against their own kind.

Who can be trusted when the enemy might be one of us?

With every battle, the lines between ally and traitor blur. Loyalties will shatter. Sacrifices will be made. And the truth, when finally uncovered, will change the course of the war—and the future of Earth—forever.

Broken Lines, the explosive third installment in the Alien Invasion War series, is a high-stakes descent into betrayal, unity, and the terrifying reality that the war for humanity may already be lost from within.
