Eve Levine, a half-demon, black witch, and devoted mother, stuck in the afterlife for three years, yearning to connect with her daughter, Savannah, now raised by Paige Winterbourne and Lucas Cortez.

Eve is tasked with capturing the Nix, a powerful demi-demon who escaped from hell, capable of amplifying dark desires and pushing people to commit murder.

Eve, using her unique connection to the mortal world, enlists the help of Jaime Vegas, a gifted witch and friend of Paige, to investigate the Nix's past victims and uncover a pattern.

Eve fears that Savannah, grappling with the loss of her mother and the complexities of her heritage, might be a potential target, forcing her to confront the possibility of losing her daughter forever.

As Eve nears the Nix, she uncovers a devastating truth: the demon’s escape from hell was orchestrated by a powerful, unknown entity seeking to sow chaos in both the mortal and supernatural realms.

Kristof, heartbroken but understanding, continues his work in the afterlife, finding solace in their shared memories and the knowledge that their sacrifice saved the world.
