While still relatively unknown to the general public, early twentieth century American horror author H.P. Lovecraft left an indelible stamp upon popular culture. Images of tentacled horrors, forbidden tomes, and protagonists struggling against the insanity that comes with the revelation of the terrible truth of reality-Lovecraft pioneered all of these. Best known for his short story "The Call of Cthulhu," Lovecraft instantiated his philosophy of cosmicism into every one of his tales. This collection of fourteen essays is the first sustained academic engagement with horror author H.P. Lovecraft from a theological perspective. Covering the major themes of Lovecraft's work such as nihilism, xenophobia, dark cults, and unimaginable horrors beyond the stars, the book is divided into five sections corresponding to each of the divisions of theology: biblical, historical, systematic, practical, and comparative. With responses ranging from admiration to critique, the contributors explore the dark uncharted regions of Lovecraft's dark mythology in the service of theological truth.
