The Goddess Idunn (also I?unn, Idun, Idunna) is commonly known as the Goddess of youth and custodian of the Apples of Immortality -?the apples that grant the Gods of the Norse pantheon continued renewal and eternal youth. Her best known, and only, myth details how she was abducted by a giant and how the Gods fought hard to retrieve her (and her much-needed apples). Beyond this, one must dig very deep to excavate any further information about her. This introductory book outlines everything we know about Idunn from historical sources, as well as what we -?her modern devotees -?have learnt from experiencing her in the modern day.
