[Nephalim Slayer]

I was recently in my local Barnes & Noble's paranormal section when I came across a book called "A Field Guide To Demons, Fairies, Fallen Angels, And Other Subversive Spirits". From the few things I know about demons I can discard this book as a fake by reading the first few pages. However, the book did create a hunger inside me for more information on demons and fallen angels and things of that category. If anyone knows a reliable source of information for this I would be very grateful if you would tell me. Thank You.

pretty decent book he did a lot of research. Well known for angel literature.

Next thing I would ask is what tradition do you want to know more about. Par example: Judaism, Christianity, Islam, Zoroastrianism, etc... all have their own concepts of angels and different stories. Also pretty much all traditions have forms of demons. So to narrow your search you should look to what tradition you are most interested in. The book I recommended is mainly Western traditions so the above and Greco-Roman/ Classical civilizations.

Hope it helps a bit.
