Noelle and her friend Alfred work nights at the Boy Meets Girl Inn--a hotel with a colorful history, as long as the color is mostly blood-red. Noelle's been keeping a diary of the weird events she's experienced: the bathroom door slowly swinging shut as if pushed, a lampshade spinning around, odd noises in the basement and other parts of the inn. There are other entries in her journal, too: things she doesn't remember writing, things that she may or may not have done, and Alf confronts her about some of her nighttime behaviors. 
 After the massacre, the diary is found, and has now been passed along to us, the reader, with annotations from the original detective on the case and from a movie exec who's been developing the source material into a script. The movie guy's annotations aren't that interesting (though it's disheartening how many times he notes that the main character has to be sexy), but the notes from the detective give some background and fact-checking on the case. 
 The end doesn't come together in any satisfying way--there are too many pieces in it that we're supposed to write off as (view spoiler)[OOH SPOOKY GHOSTS AND POSSESSION (hide spoiler)] but they don't gel together quite right. 
 For high school collections (lots of swearing, primarily).
