The girls were super excited for the slumber party on Friday. One of them brought a book for them to read horror stories, and that was the most anticipated part of the night.

A ritual, as the book indicates, is what they end up getting into, and it most definitely isn't harmless. Shrouded in mystery and suspense, the morning comes... and all the horror of that night was just the beginning.
