By Douglas Hill & Pat Williams.
Where do we start with how awesome this book is? It is THE bible on the occult and covers everything from satanists, witches and voodoo to orgiastic rituals and cults. And beyond to supernatural occurrences like poltergeists and apparitions. The best part (besides the cover) are the photos! Bring on the campy 60s horror film style nightmares!
