October 31 is another frightening Halloween night, for it is Josie Bells's twenty-first birthday, the day her baby sister Angel Bells has been dreading. Josie's coming home from Safe Haven, a mental institution she's been in for the last eight years. She's coming home to start a new life in Jacksonville, Louisiana, with Grandpa and Grandma Baker. Angel is not at all happy with these arrangements. She fears for her and her grandparents' lives. After all, Josie has killed once and can kill again. Angel isn't going to let that happen. Angel has made a thirteenth-birthday vow of her own to save herself and her family from her sister Josie.
Jacksonville will be freed from the Bellses' deep dark secrets and their evilness once and for all.
