Hollow Girl: Behemoth (Hollow Girl #8)

Young Ellie is running through the woods - running from the Forgotten People and the demon to which they intend to sacrifice her. Behemoth. And it doesn’t matter whether Behemoth is real or just a distortion of a local legend, the insane cult will kill her just as dead either way. But there is someone coming to save her, someone who’ll brave an army of cultists and a legion of demons - Ellie’s mother. The only problem is that she’s dead. Fortunately, there’s an unstoppable vigilante-medium on hand to give her soul a ride. - Hollow Girl.
