This is one of my favorite demonology books. It's a great first book for anyone looking to get into demonology. The stories are very short, yes. And true, they don't cover ALL of the demons. But this is a FIELD GUIDE. As in, a guide you take with you into the field. Therefore making it an easy go-to book when looking for information quickly. The pictures are wonderful, and the organization is crisp. My fiance and I just had to buy a second copy, as our original is quite beat up from use. Definitely worth the money!
