Bone Adams is a legend, the best mortician in the Spires, and a man without modification in a world where body mods define humanity. When a new killer begins leaving bodies stripped of mods but twisted and bent into grotesque pieces of art, City Officer Stark tasks Bone to unravel the clues, few though they may be.

As more victims are discovered, Bone and Stark get drawn deeper into a world where pain and personal statement blend and blur, and finally end up hunting for a semi-mythical, man-machine named Burneo deep within the labyrinth of the sewers.

But things aren’t what they seem, and while searching for Burneo, Bone and Stark discover a hidden lab full of evidence of horrific abuses of science and experimentation. Meanwhile, the killer is still on the loose, and, as Stark becomes more and more obsessed with the case, Bone is forced to a shattering realization. Everything is connected, the killings, the gang activity, the labs, and his own past, and unless he can figure out how, he’s not going to survive.

Ren Warom weaves a tale laced with gang crime, underground body mod shops, Transmog labs, and shocking murders, and ties it all together with a protagonist desperate to shed his father’s reputation and become his own man. But at what cost?
