Trick or Treat (фемслэш)

Kate Marsh: dutiful daughter, exemplary member of the Church. In a world of judgment, fear, and strictures, that's who she's allowed to be. Only one night a year does she allow a glimpse of her real self.
That changes when she attends Blackwell. Away from the people that would judge, constrain, and condemn her, she decides for the first time in her life to embrace who she is. Life will never be the same.
