I'm just reading a review of a new book of Shirley Jackson's letters, which in turn made me want to re-read her short story "The Lottery" again. Most people who've read it seem to have read it when young, probably because the language is simple, but it seems to me that it stays with you, no matter what. When it was originally published, it triggered more reader mail than any other fiction piece, ever, to date.
If you haven't read it:
