There are some books that really help those on a spiritual journey to find the path they seek. Then there are books that are obviously written to cash in on a trend. This is one of those books. Be wary of authors who write about a variety of subjects without focusing on a single discipline. It is more than likely that they are in it for money. If you want expert advice, find a true follower of that religion or a scholar of that subject and avoid authors who write a different "expert" book every other month on an entirely different subject. There's nothing of Odin in this book. I won't even go into what's wrong with the phrase "Teutonic Magick".
In this book the author takes Wiccan Rites and places the Norse gods into them. This book is not appropriate for those looking for authentic Norse Rites. If, however, one is just wanting to work with these gods in ones own rites this may be worth a look.
For those who are wanting to learn about this culture or way of life directly, I suggest reading the Eddas and legends of this culture.
