Who goes on to flipping her life upside-down when he reveals her home town's weirdest secret: The town is a prison for supernatural beings who have committed awful crimes, and her high school is apparently full of crazy supernatural criminals.
And now that she knows the secret, Ophelia's life can never be the same.
Zariah Croft has never had a normal Halloween. She is not allowed to go Trick-or-Treating, not allowed to dress up, and can't even decorate the house. But when her mother and her move to the city of Crossing, they find a community that is obsessed with the candy holiday. And apparently, in Crossing, Zariah's decision to engage with the world's most fun holiday isn't a game... It's a decision that might just get her killed.
