"As compelling and smoothly chilling a tale as you'll find this year. The Demonologist shows an enormously gifted writer at the top of his game, producing a novel of eerie menace and unique depth. Those of us who write supernatural stories do not throw the names Ira Levin, William Peter Blatty, and Peter Straub around lightly. You'll be hearing all three associated with Mr. Pyper soon, and all such comparisons are warranted, the highest praise I can offer."
