When strange disappearances begin spreading across Columbus, Marcus Webb thinks he has found the story that could make his name. A piece of footage captured deep in a drainage tunnel shows something impossible-something tall, scaled, and inhuman moving through the dark.
What starts as an investigation quickly turns into a nightmare.
Beneath the city, a hidden species is hunting. Above it, something else is watching.
As more people vanish and the evidence grows harder to deny, Marcus and a small group of survivors uncover a terrifying truth: humanity is caught between two separate non-human threats. One comes from below, stalking the tunnels, sewers, and forgotten spaces beneath American cities. The other descends from the sky, taking victims and returning some of them changed.
With society refusing to see the danger until it is too late, Marcus and his team are forced into a desperate fight for survival. Armed with stolen data, underground maps, and fading hope, they must uncover what these creatures want before the war reaches the surface in full.
Because this is no longer a mystery.
It is an invasion from above and below.
