The King in Yellow by Robert W. Chambers.

I was re-reading this book the other day, and I had forgotten just how good it is; particularly the first story “The Repairer of Reputations.” I first came across it about a year ago while reading about H.P. Lovecraft, and I must admit that, while Lovecraft’s ideas are more carefully thought out, Chambers’ writing is actually superior to Lovecraft’s, and his overall technique makes for some of the best weird fiction I have ever read, period.

If you happen to like that sort of thing, check it out.
