“An unnerving and surreal meditation on the demons that haunt us and on the nature(s) of evil. Compelling and unsettling” (Brian Evenson, author of Song for the Unraveling of the World). Thomas hears voices, and the worst of these voices belongs to a demon called Dinn. In a series of increasingly horrific rants, the demon reframes Thomas’s declining mental health as a part of a secret training program, an occult procedure designed to cultivate the demons of tomorrow. In the distorted world depicted by Dinn, gateways to hell lie behind every door. Friends and family are the enemy. And the only way for Thomas to survive his training is to dedicate himself to the demon’s prescribed rituals of loneliness, ill health, and pain. Equal parts ferocious and seductive, Mutilation Song is a boundary-shattering horror novel that uses a hallucinatory narrator to explore the extremes of mental illness. “A fabulous nightmare of hypnotic logorrhea, strewn with visions worthy of a Clive Barker on acid.” —Nicolas Winter, Just a Word “Mutilation Song is without question a poison, but it is also a kind of scripture . . . You’re gonna love this one.” —Tony Burgess, author of Pontypool Changes Everything “Jason Hrivnak, who, with The Plight House, made a masterful entry into the literature of malaise, now gives us this new Song added to hell, this poetical call to damnation.” —Alain Nicolas, L’Humanité “Dazzling and suffocating, this violent plunge into the demonism of schizophrenia opens an entire world-in-a-book, a labyrinth of shifting voices, of truths to be deciphered . . . A truly great novel.” —La viduité
