A child marked. A bloodline exposed. A relentless evil refuses to let go. They thought Lucy was safe. But after a violent incident at school leaves another student traumatized, the truth is undeniable-Nora's daughter is anything but normal. Her moods shift without warning. Her eyes darken. And she whispers to the shadows in a voice not her own. As the thing inside of Lucy tightens its grip, Nora and Ally are forced to confront a horrifying realization-they never outran the evil. It was only waiting for the right moment. Desperate to save her child, Nora and Ally enlist the help of Father Tony to unravel their mother's buried past, uncovering a legacy of forbidden rituals, broken vows, and a debt that was never paid. What they discover is worse than possession. Lucy wasn't chosen at random. She was prepared. As Lucy slips away, the evil grows stronger. The attacks escalate. The line between protection and sacrifice begins to blur. Every attempt to save the child only draws the darkness closer, until Nora and Ally are faced with an impossible truth: Some doors cannot be closed. Some demons cannot be cast out. And some legacies demand blood. The Last Demon is Book 3 in the Dark Covenant series-a chilling occult gothic thriller packed where love becomes a liability, faith fractures, and saving a child may cost everything. Fans of Jennifer McMahon, Thomas Olde Heuvelt, Lee Mountford, J.R. Erickson and Nick Roberts will love this creeping supernatural nightmare.
