The Haunted School (Goosebumps, #59) - R.L. Stine One of the more frightening goosebumps books by far. I read this at an age where I was slightly past the acceptable age for reading goosebumps books (maybe 14?) and it still managed to scare me. I think R.L.Stine often tells stories that are a bit too weird to be appreciated in the horror genre, but his Nightmare Hour and Point Horror collections are far better in general than the goosebumps. He tends to build up very scary tension and keep you on the edge of your seat... and then it all comes out that it's part of a project, or a dream, or everyone is really from another planet. It just crosses the boundaries of weird and makes what could be a clever horror ending into a bit of a joke.
The point of me saying this is to emphasise how I think this book manages to stay outside of this and delivers a good shot of the horror we love. I liked it.
