Witchcraft from the Inside.
This is a complete history of witchcraft, including its origins in prehistory, its decline in the dark ages and its rebirth in the 20th century, as collected by an insider rather than a detached observer. I found the book to be well researched and documented, which more than did justice to the subject matter. While I enjoyed the information accumulated in a cover-to-cover reading, Witchcraft from the Inside is also a valuable reference tool.
