To be the Goddess of Eternal Youth is to be the most important among the Aesir. But it can sometimes be a tedious existence. Enticed by her friend, the Trickster-God Loki, Iduna dares to leave the Realm of Asgard and descends to Midgard, where only mortals dwell. She arrives amidst preparations of a spectacular feast and is drawn into the merriment.
Then, she meets the mysterious and charming Thomas. He is unlike anyone she has ever met before, and is overwhelmed by him. Yet, as the last stroke of midnight nears, she realizes that Thomas may not at all be as he appears.
