Darklands - Nancy Holzner

Boston's demons have been disappearing and Vicky's clients are cancelling left and right. While fewer demons might seem like a good thing, Vicky suspects foul play. A missing Celtic cauldron from Harvard's Peabody museum leads her to an unwelcome conclusion: Pryce, her half-cousin and bitter enemy, is trying to regain his full powers. But Pryce isn't alone. He's conjured another, darker villain from Vicky's past. To stop them from destroying everything she loves, she'll have to face her own worst fear in the realm of the dead itself.
