A psychic tells your heroine to stay home on New Year’s Eve. (Why was your heroine talking to a psychic? What brought her there and does she believe in psychics?)
As luck would have it, your heroine does end up staying home on New Year’s Eve. (Did she intend to or did her plans fall apart? If they fell apart, what happened?)
A loud knock on the door at 11:55pm wakes her up. She’s on the couch and unsure whether she should answer the door or not. The knocking continues and her instincts are at war with one another. Curiosity wins out and she answers the door. Who is there? What happens?
