Vitreous

In the workshop of Isidore Krell, the eyes don't just mimic sight. They steal it. Arthur Penhaligon is a desperate man seeking a trade in the fog-choked district of Needle Street. When he is hired as an apprentice to Isidore Krell, the last master ocularist in London, he believes he has found salvation. Krell is famous for creating "bespoke visual organs" for the wealthy and the scarred-glass eyes so realistic they seem to hold a spark of life.
But the workshop is a place of cold furnaces and staring silence. Thousands of eyes line the shelves, tracking movement in the gloom. The "glass" Krell uses isn't silica, but fulgurite harvested from sites of ancient massacres, ground down to capture a psychic charge. And the clients don't come to look normal; they come to see the Ether, a spectral layer of reality populated by the dead. As Arthur tends the kiln, he realizes the eyes are addictive.
Once inserted, they bond with the nerve, refusing to be removed. And they are not just prosthetics-they are cameras. Krell is building a living surveillance network across the city, and he is missing one final component. Arthur tries to flee, but the fog of Needle Street is thick, and the truth is already staring him in the face. He wasn't hired to be an apprentice. He was hired to be a donor.
