Satan's Disciples is essentially a metaphysical thriller and a crime novel dealing with the nature of evil and the spiritual cost of revenge. The plot involves an Albuquerque Times investigative reporter named Michael O'Brien who is shot in at LAX by a young madman targeting TSA agents. He develops PTSD and spends his convalescence trying to understand why it happened. In his research of random shootings and murders of innocent people in incidents like the Son of Sam murders, the Navy Yard shootings, Sandy Hook, the Aurora Mall and others, he discovers that satanic influence links many of the mass murderers. As he recovers and is ready to return to work, he gets permission from his editor to expose the hidden Satanism going on in New Mexico. To do so, he infiltrates the Devils Disciples motorcycle gang. He witnesses a Black Mass and tries to prevent the ritual human sacrifice of a teenage girl which blows his cover and propels the reader on a fast paced, intense pursuit of the victim, the gang members and O'Brien himself. The fast-moving plot and colorful characters reveal the hidden pervasiveness of Satanic cults in America, the evil underbelly of outlaw motorcycle clubs, the ruthlessness of the cartels, the invisible black market for kidnapped babies, and the ineptitude of the FBI, the Border Patrol and local police in dealing with smart and ruthless criminals. On a psychological level, Michael O'Brien leads us through the suffering and post-traumatic stress of being an innocent shooting victim, his intellectual quest to know if God or the Devil really exist, his anxious attempt to prevent a murder by a satanic motorcycle gang, and the spiritual bankruptcy he experiences as he wades deeper into his mission of revenge against the miscreants who destroyed his life.
