There is only one person in the whole world who remembers the famous prophet Astrid Glyn: the berserker Soren Bearstar. Ever since Astrid agreed to give up her life, her name, and even her prophetic dreams to become Idun the Young, the almost-goddess who protects the apples of immortality in a secret mountain orchard, she’s been forgotten by everyone. Everyone except Soren. For the last two years he’s faithfully visited her every three months. Then one day he doesn’t come. Though forbidden to leave the orchard, Astrid defies the gods by escaping with a bastard son of Thor to find Soren. But ancient creatures are moving in the mountains beneath the country. They are desperate to leave the shadows and Astrid’s quest might be the key they need. Not-quite-a-goddess, but no longer only a girl, Astrid must choose a path that will save herself and the people she loves without unraveling the ancient magic that holds the entire nine worlds together. Welcome to the final chapter of the United States of Asgard.
