H.P. Lovecraft

Hey there /book/

I am really in the mood for a good horror novel this month, H.P Lovecraft in particular. Can you guys suggest what his best works are? You know, something that will really mess with my mind

I thought The Whisperer in Darkness was great. I heard it's being made into a silent movie at the moment by the same guys who did the Call of Cthulhu silent movie.
