Seventeen-year-old Soren Bearskin fears both the past and the future. His father, a famed berserker warrior, went to prison after killing thirteen innocent people during a mindless battle-frenzy. Berserking is in Soren's blood, too: constant fevers and insomnia promise the power will explode in him any day. He's terrified of himself. When Baldur - Odin's son and the god of light - vanishes, Odin offers a boon to any who bring him news of his son. Soren sees his chance to change his fate: with that boon, he could ask Odin to strip berserking out of him forever. Along with Astrid Glyn, a teen prophet who's dreamed of Baldur's location, Soren takes off on a road trip across the United States of Asgard in search of the lost god and a new future.
