Heathenry for the Absolute Beginner
Crossley-Holland, Kevin; The Norse Myths. A terrific, approachable introduction to the major myths of the Norse people.
McNallen, Stephen; Asatru: A Native European Spirituality. A great introduction to Asatru from a Folkish perspective.
Pollington, Stephen; The Mead Hall. The definitive book on the ritual of sumbel, or ritual drinking.
Thorsson, Edred; A Book of Troth. An equally great introduction to Asatru from a non-Folkish perspective. More practical in terms of rituals.
Ibid, Futhark: A Handbook of Rune Magic. Still remains the definitive introduction to the runes from a magical perspective.
