The Oxford Book of Scary Tales is a spine-tingling collection of strange and spooky stories. There are ghosts and ghouls of course, but there are also other eerie stories, about the nature of fear itself. An excellent range of authors includes Geraldine McCaughrean, Susan Price, Ian Serraillier, Ruskin Bond and Dennis Hamley.
These are English stories full of English slang and will require some explanation for most American kids. Not all of them are about supernatural things, either, but about the tricks your mind can play on you. But there were still a few with genuine haunts. In general these stories felt like adults taking down the stories children tell each other and dressing them up a bit so they were more presentable in print.
I read this to see if there were any stories I could use for library class at my kids' school. In the end I think there are at least a couple that will work. I particularly liked the poem "Miller's End" by Charles Causley, which, along with "The Slitherydee" by Robert Scott, will be good as an exercise in memorization.
