Demons
A novella.
In a future uncomfortably close to today, the apocalypse has surpassed all expectation. Hideous demons roam the streets in an orgy of terror, drawing pleasure from torturing humans assadistically as possible. Ira, a young San Francisco artist, becomes involved with a strange group of scientists and philosophers trying desperately to end the siege. Ira and his allies believe these demons were summoned. But what if it isn't demons who possess men, but men who posses the demons?
John Shirley
John Patrick Shirley (born 1953) is an American science fiction and horror writer of novels, short stories, and television and film scripts.
John Shirley's most significant cyberpunk novels are City Come A-Walkin and the Eclipse (A Song Called Youth) trilogy. Avant-slipstream critic Larry McCaffrey called him "the post-modern Poe". Bruce Sterling has cited Shirley's early story collection Heatseeker as being a seminal cyberpunk work in itself. Indeed, several stories in Heatseeker were particularly seminal, including Sleepwalkers, which, in just one example, probably provided the inspiration for William Gibson's "meat puppets" in Neuromancer. Gibson acknowledged Shirley's influence and borrowing ideas from Shirley in his introduction to Shirley's City Come A-Walkin.
