Fans of the blockbuster television phenomenon can rejoice! A one-of-a-kind compilation of all of Sam and Dean's demon-busting knowledge, The Supernatural Book of Monsters, Spirits, Demons, and Ghouls contains illustrations and detailed descriptions that catalogue the more than two dozen otherworldly enemies that most people believe exist only in folklore, superstition, and nightmares:vampires, ghosts, revenants, reapers, and even bloody clowns. You'll find within these pages Sam and Dean's notes, observations, and memories interwoven with sections of John Winchester's invaluable journal, making this book the perfect companion to every thrilling episode—and an essential weapon in the secret war against the hidden creatures of the darkness!
