When Graham leads his convoy through the rusted gates of Hanford Nuclear Reservation, they aren't looking for hope. They're looking for walls thick enough to survive behind. What they find is something no one could have predicted — five men who never left, buried beneath the most dangerous ground in America, keeping a dying machine alive for fifteen years so that no one else would have to.
The Watchers don't speak much. They don't offer comfort. They communicate in protocols and radiation readings and the particular silence of people who have spent so long being necessary that they've forgotten how to be known. But they're still standing. And in the world Graham's people have crossed half a continent to escape, that counts for everything.
Meanwhile, beyond the perimeter, something is changing. The scattered remnants who have hunted Graham's people for years are no longer scattered. Someone is organizing them. Someone with resources, coordination, and a very specific interest in what Hanford is hiding.
The detectors glow green. For now.
