Gaslight. Demetri Risk

Dauphine Gautier came home to New Orleans hoping to disappear. Instead, she found herself hunted. When a dangerous spirit from her past resurfaces, Dauphine is forced to confront the consequences of a killing she made in self-defense-and a powerful enemy who wants far more than her life. As the boundary between the living and the dead begins to fracture, Dauphine turns to old allies, ancient magic, and a gris-gris charm that may not be strong enough to save her.
Set in the shadowed streets of the French Quarter, Gaslight is a dark urban fantasy steeped in voodoo lore, coven politics, and supernatural menace. With witches, vampires, and restless spirits colliding, Dauphine must decide what she's willing to sacrifice to finally be free. Gaslight is a Demetri Risk-adjacent story, expanding the world beyond the case files into the dangerous magic lurking just beneath the surface of New Orleans.
Some ghosts don't stay buried. And some magic always comes at a cost.
