Unfortunately, there are very few good books out there on demonology, and this one was definitely not one of them. The entire thing (consisting of about 100 or so pages) is written in a HUGE font which very well could filled up 50 pages in a normal book. However, the most irritating part about it was the fact that it's entirely based on the bible (or "the Word" and Mr. Lester Sumrall puts it). This was not at all what i was hoping for, and will never again make the mistake of purchasing something written by him again. If you are still looking for a good read on demons etc., try "A Field Guide to Demons, Fairies, Fallen Angels, and Other Subversive Spirits" by Dinah and Carol K. Mack. It is the most helpful and informative one I have found so far.
