Friday the 13th

Alexandria wakes on one cold depressing Friday morning. Little did she know that it wasn't any normal Friday. When she awakes she finds that her parents are missing and something terrible has happened to her grandmother. Someone, well more like something, gives her a hint of where to go. As she readies for her adventure more horrifying things are found. Some even in her own home. Will she figure out whats going on? Will she find her parents?
