I just finished reading The Mammoth Book of Haunted House Stories, and I must say I have mixed feelings. It is, as the title suggests, a very large collection, and I came away with the impression that the quantity of ghost stories was favored above overall quality. I do not want to leave you with the impression that it was entirely rubbish; there were a handful of selections that made the whole thing worth it (Ghost Hunt and Napier Court, to name a couple). If, like me, you are in the business of expanding your library, then it may be worth your time. I would advise looking through your own ghost story collection to make sure you are not getting too many duplicates before buying this book.
