A basic primer on Germanic magic covering galdor, rune magic, spá or divination, seiðr, and a variety of other magical practices not readily identified.
I love Swain Wodening's thought process on explaining his sources, some of his books can use an extra run through spell check by the editor. Often words are crammed together without a space in between, or the table of contentents may not line up with the pages. But these things aside, his books are among my favourites.
