The latest novel from Matt Casamassina, author of Sophistication, which Kirkus Reviews called "Ambitious. Well-paced. Riveting. [Casamassina] occasionally reaches moments of lyricism.”

Mason Kowalski, a twenty-four year-old copywriter for a San Mateo startup, is on the verge of a nervous breakdown when he inexplicably suffers widespread vision loss in one eye. The doctors say it’s macular degeneration triggered by overwhelming stress, but he wonders if it’s something more, especially when the shadows in his peripheral vision begin to take shape and whisper wonderful and horrible things to him. Is it madness or destiny? The answer could destroy everything and everyone he holds dear.

Journey into the absurd beating heart of Silicon Valley as Mason and his lovable friends scramble to stop a demented serial killer from murdering more children. Degenerate mashes horror and sci-fi into a twisted, dark, violent and funny pulp drowned in tentacled nightmares. Featuring infamous hijacker DB Cooper and more twists than you can imagine, the genre-breaking story is designed for fans of Stephen King, Blake Crouch, Peter Clines, Keith Rosson, Chuck Wendig and John Scalzi.
