It's the holidays in New Orleans! It's eerily cold and dark and snowflakes are falling. Mrs. Hart is getting ready for their big New Year's Eve party and pushes Bernice to be more sociable. In the process tales of legends in New Orleans are spun from Bernice's neighbor, Nona Devereaux, to her and her new trouble-making friend, Ellie.
After sneaking off into a white covered St. Louis Cemetery No. 1, Bernice makes her way home feeling goosebumps and falls asleep into the realm of Shadow Witches where she finds chaos, mischief and whispers in the dark. Guided by her Keeper, Gracie, they discover what persuades children into broken dreams and come face to face with a family secret and, more importantly... a key to rescuing a loved one lost long ago.
