Bridget Saunders, a devoted high priestess and worshipping disciple of Satan, frantically knocks on the front door of FBI agent Magdalena Aragon, the born-again daughter of her childhood friend, desperate to find redemption in Magdalena's God. After spending most of her life drinking from the golden chalice of sacrificial human blood, it is the beginning of her transformational journey from the depths of darkness into the glorious light.

In the midst of her own journey, God brings Agent Aragon into the path of a young woman who will unlock the truth of the cold case of Regina Delgado and her "Trust no man" hallmark tattoo. What she uncovers is the darkest rabbit hole she has ever fallen into--the underground world of black magic. The nefarious and egomaniacal depth of the cult kingdom, the criminal world entrusts, to secure themselves from the FBI's prosecution is now Agent Aragon's weakest link.
