I'm a big fan of H.P. Lovecraft fiction. The King in Yellow was interesting for me as it is well known that the great Master took some inspiration out of Chambers work.
Not all stories are the same quality but most are very good and some of them are really small masterpieces.
The Yellow sign or the King in Yellow itself appear in nearly every story, and those who don't contain this subjects are linked to the others that do by small, casual connections.
People reading Poe, Lovecraft and similar authors should like this small book very much.
