The war isn't over. The dead aren't done. And this time, survival means choosing sides.

Master Sergeant Yaël Sion has finally earned her place among the last elite special operators on Earth. After the fall of nations and a brutal proving ground of fire and blood, she's found something she never expected to have again—a team. A home. And brothers she would die for.

But when they're called deep into the remote killing heights of the Hindu Kush, Yaël and Alpha team drop into a nightmare of ambushes, relentless enemies, and a battlefield that devours the unprepared. They're not just fighting the dead—but facing hardened survivors of the last war, ruthless, bloodied, and desperate enough to kill anyone who dares violate their home ground… including beleaguered Ranger and Marine Raider brothers sharing the same lethal battlespace.

When the operation spirals out of control, the team barely escapes with their lives—and the consequences follow them home.

As USOC launches increasingly desperate missions to claw back humanity's future, Yaël is forced into battles that test more than her skill with a rifle. A brutal operation in Ireland pits Alpha against fanatical holdouts who refuse to surrender anything—least of all their power. At the same time, ghosts from Yaël's past resurface, threatening to tear her from the only family she has left… or destroy it entirely.

Loyalty will be tested.

Trust will be broken.

And survival will demand a price none of them are ready to pay.
