Kvilhaug's book of The Goddess Iðunn uncovers her true associations and links through poetry and myths. Iðunn is often linked to concepts like youth and fertility, but why is this? Kvilhaug examines why she is so often linked to these concepts and offers to comparative view of the goddess to other myths that often depict similar goddess in the same light despite the fact that they do not share any actual source depicting them as such.
