Tunnel Out of Death

In Jamil Nasir's Tunnel Out of Death, Heath Ransom, former police psychic turned machine-enhanced "endovoyant" private investigator, is hired to find the consciousness of the rich and comatose Margaret Biel and return it to her body. Tracking her through the etheric world, he comes upon a strange and terrifying object that appears to be a tear in the very fabric of reality. He falls into it-and into an astonishing metaphysical shadow-play.
