When Ulla Tulin took her internship at the Mimirin, the only mystery she thought she'd have to solve was that of her birth parents. After a girl named Eliana gets kidnapped while in her care, Ulla knows she has to find out the truth of who Eliana really is--and the only way to do that means traveling to the Omte capital, the place she suspects her mother is from. Ulla didn't expect that when she arrived she would discover the identity of a Skojare man who crossed paths with her mother--a man who could very well be her father. When the head of the Mimirin learns Ulla's father is connected to the Älvolk, a secret society who believes they were tasked with protecting the First City and the only ones who know its location, he sends Ulla and Pan to Sweden where they find him living among the Älvolk. But all is not what it seems with the Älvolk and their urgent quest to find the Lost Bridge to the First City leaves Ulla feeling uneasy--and possibly in danger.
