Heroic in the face of certain death, the Gods of Asgard will not survive the final battle. Cathal and Lucy leave their own world to save the magic of the Runes. Cathal is not a usual boy. His father is an eco-warrior; his grandfather is in prison for protesting against war. On his fourteenth birthday, Cathal decides to seize the magic of the Runes. He does a ritual to begin his quest, but finds himself taken by Magician God Oðin to the Nine Worlds of Yggdrassil. Lucy thinks she is a very ordinary girl, but when Oðin takes her from under the eyes of her horrified classmates to join Cathal in Midgard, it turns out that Lucy has magical powers of her own. They discover the Nine Worlds are heading to destruction. Through love, courage and cunning, Cathal and Lucy try for themselves the magical tests where Oðin first won his great powers. Can the deep prophecy be invoked? Can the magic of the runes be preserved and a new world created?
