This being Halloween it is pretty important to be on guard for strange happenings and creatures. Sure you can learn a lot from watching all of the episodes of Buffy, back-to-back as friends of our have, but that can only take you so far as the cast of characters is always the same over a hell-mouth. Demons lurk everywhere. You might encounter; a Tommy-Knocker or a Windigo while hiking, a Kelpie near the shore, Kitchen Faeries making a mess in your house, or even your Id causing trouble enough harm drive you to therapy. A Field Guide to Demons, Fairies, Fallen Angels and Other Subversive Spirits arms you with information to identify, and defeat them all.
