Long after his death, H. P. Lovecraft continues to enthrall readers with his gripping tales of madness and cosmic terror, and his effect on modern horror fiction continues to be felt-- Stephen King, Anne Rice, and Clive Barker have acknowledged his influence. His unique contribution to American literature was a melding of Poe's traditional supernaturalism with the emerging genre of science fiction. Originally appearing in pulp magazines like Weird Tales in the 1920s and 1930s, Lovecraft's work is now being regarded as the most important supernatural fiction of the twentieth century.
