Detective Logan Ward is a man hollowed out by grief, a shadow moving through the neon-drenched, rain-slicked streets of Aethelburg. But when he is assigned to a string of impossible suicides, he discovers a horror that defies the three dimensions of human understanding.

Following the trail of the "Klein Manuscript," Logan is led to a house on Escher Street that shouldn't exist-a place where geometry is a weapon and the walls breathe with the echoes of the damned. As he peels back the fabric of reality, he realizes these victims didn't just end their lives; they were harvested by a predator from the 4th dimension. In this mind-bending cosmic horror, Logan must decide if he is chasing the truth or simply walking into the aperture of his own eternal torment.
