Book excerpt: Waking up in Mictlan, the underworld entrance of the North, nearly dead from an evil witch's attack—this is where James Endredy's gripping true account of his experience with the witches of Veracruz begins. As the apprentice of a powerful curandero, or healer, Endredy learns the dangerous magic and mystical arts of brujería, a nearly extinct form of Aztec witchcraft, and his perilous training is fraught with spiritual trials and tests. Taught how to invoke spirits of the underworld for assistance and use dream trance to "fly," Endredy is subjected to the black magic of a brujo negro and left alone in the graveyard of the brujo masters to fight for his life. He is also called upon to do battle with the most sinister of all witches—el Brujo de Muerte, the Witch of Death. Upon becoming a curandero himself, Endredy takes on harrowing real-life cases: healing a young man possessed by the spirit of an Aztec warrior, rescuing a teenage girl from a Mexican drug cartel, and hunting down a vampire witch terrorizing a small community.
