The premise, in the publisher's words

The war ended in a blinding flash. Now, the earth is hollow, a fractured shell hiding the remnants of humanity. A new era of evolution is about to begin. Survivors fled underground, but salvation was a lie. A sickness spread, warping minds, twisting bodies. No one is being spared. You are a child, taken to a hidden facility deep below the surface. You don’t know why. Only that you’re sick. That everyone is. And something is wrong. You have to escape. Crawl through the vents. Follow the echoes to get to the surface. Your mother is waiting for you.
