Failed reporter Thea lives a quiet life in the small city of Paisley, Scotland. Eking out a living at the local bookstore, she secretly yearns for adventure. Elsewhere in the Nine Realms, Odin, the All-Father of Norse myth, learns of a young woman destined to carry the weight of all existence on her shoulders. Worlds collide as Loki, the Trickster, escapes from his prison and is sent to locate this woman. Finding Thea among dusty books, he is strangely drawn to her, a connection that pulls them both into world-shaking events and devastating confrontations. The Aesir rally to battle an enemy that aims to destroy the entire Nine Realms, but they may need to rely on a frail human to deal the killing blow.
