Book: Teutonic Magic The Magical And Spiritual Practices Of The Germanic Peoples by Kveldulf Gundarsson

This is not a dry academic book. Gundarssons' writing flows like the sagas themselves, covering subjects such as norse deities and rituals. It describes the structure of the spiritual realms in which the Norse magician would walk. It is no wonder that this book is considered the classic text book of anyone who would study runes or the northern tradition.
