I'm giving this 3.5 stars bc the style of writing is one I enjoy - a focus on the little details, philosophical musings, musings on the mundane. But the story itself gets perhaps at most a 2. The plot reads like a story written in a middle school english class in response to a prompt that asks something like "write a story where things aren't as they seem". The characters thoughts and conversations, though, are more of the meat of the book than the actual plot which made it more enjoyable to get through. 

I thought the story was going to grow into something completely different than it did when they were at the parent's house, and it was at that point that i was intrigued. However, the moment they leave the parents' house and go on to the school it was more like. oh. okay. I do however continue to wonder if the entire book was that found beside the janitor in the end, or if the book is his writing (what if i did give her my number and we got together, going even to my parents' house) + a narrator who is noticing the inconsistencies of the book she is written in. Is she noticing the amateur writer's failing to be consistent - the second band aid over the eye, the bandaid now over the toe nail, the painting in a basement without supplies, the indecision of who the narrator is - or is she written by him to be this way? Does this imply that the janitor himself was interested in psychological horror that then acted out the end of? Does it imply he doesn't know himself, having a psychotic break? Why then would he write it out in this way? This is the main thought that lingers.
