Cannibalism, Blood Drinking and High-Adept Satanism by Kerth Barker is a memoir and investigative work that details the author's alleged experiences as a survivor of Satanic Ritual Abuse (SRA) and his insights into a supposed global, underground network of Satanists. Written as a follow-up to his book Angelic Defenders & Demonic Abusers, it purports to provide insider information on the darkest, most extreme aspects of occult practices.
