An ecological detective story told amid a backdrop of fantasy and science-fiction.

When a mysterious giant of a man arrives in a vast steampunk megalopolis, death walks beside him, leaving a trail of corpses in their wake. It's up to a dysfunctional yet dogged police investigator to find the strange colossus and stop him before the bodies pile even higher. Soon the truth is discovered that this case is far more complicated than the detective could've possibly conceived: a veritable battle between nature and city is unfolding, whose very outcome could forever change the face of the earth.
