This is one of the very few books about runes, written from an esoteric perspective, that shows respect for the history and traditions of the North. The majority of rune manuals merely use the symbols as a vehicle to carry an author's New-Age message, without any research into the historical facts.
Pennick is a bright exception. His many years as an active Pagan has given him a real respect for Pagan and Heathen traditions. His scientific background has given him an eye for detail, and an ability to dig up the facts.
Although it does contain sections on the "rune yoga" daftness, and some other New-Agey stuff, these can be ignored without diminishing the quality of the book.
The quality of this glossy tour of runic lore is unique. I would recommend it as one of the best introductions for those interested in the runes, whether for divination, or as part of their heritage.
