Fiddler's Green Peculiar Parish Magazine has been producing a wonderfully elegant, downright enchanting series of zines, of which The Ring of Truth is the most recent.
Yes, this "zine" is not your common photostatted punk zine. Far from it, in fact. This really is a piece of art - and it is beautifully illustrated by Alice Cao's fine linework.
The text itself is composed of a wistful literary reminiscence, extremely well-written, about Marsh's first childhood brush with the magic world and his later (succesful) attempt to invoke a window to that world by means of a magic circle. Following this is a practical guide to creating a sacred space AKA a magic circle (which really need not be a physical space at all). A "Further Reading" section provides a brief, but focused bibliography on the subject matter at hand.
Saying much more than this would spoil your enjoyment of the book and some of the little discoveries to be made therein. The magic is there, but you need to find it yourself. I suggest drinking some Ginger Beer out of one of Trevor Foster's wonderful skull mugs as the perfect, almost magical, complement.
