H.P. Lovecraft was the inventor of cosmic horror, of weird fiction and the Cthulhu mythology. His stories, incubated by a lonely and febrile childhood, found purchase in the fertile earth of pulp fiction where he inspired many other writers, from Robert E. Howard, to Robert Bloch and Clark Ashton Smith, many of whom also collaborated on the several short stories, some of which are also included here, in this special deluxe edition.
