"Abdul Alhazred" (numerous editions by various authors)
Review:
Marketed as real but utterly fake, the Necronomicon (“Book of Dead Names”) existed only in H.P. Lovecraft’s horror fiction, and even there only by allusion to its eldritch-sounding title. But if you’re a Lovecraft fan like *Diuvei, you’ll want to have it on your bookshelf just for its own sake — and to observe who does or doesn’t recognize it for what it is.
