Polterheist: Book Five of Esther Diamond

In the days leading up to Christmas, struggling actress Esther Diamond is working as a singing-and-dancing elf at Fenster & Co, a major Manhattan department store. As if dealing with hordes of holiday shoppers isn't bad enough, Esther's ex-almost-boyfriend, Detective Connor Lopez, is on the scene investigating a series of mob-related truck hijackings of Fenster's merchandise. Semi-retired hitman Lucky Battistuzzi is also nosing around, since the mob resents being implicated in thefts they didn't commit. But when supernatural mishaps occur, Esther realizes this is more than the usual holiday insanity—it's time to call in her friend Max, Manhattan's resident mage. Esther and Max discover that Fenster's has become the staging ground for the rebirth of an ancient demon that's plotting to escape its mystical prison on the winter solstice.
