Meanwhile in Sweden Klara Walldéen returns to the Stockholm archipelago to bury her beloved grandfather, her best friend Gabriella by her side. What should be a trip of mourning and solitude quickly turns perilous, however, when Gabi is arrested under suspicion of terrorist activity. After finding notes in Gabi’s purse about a clandestine meeting with a young Swedish diplomat, Klara springs into action, determined to clear her friend’s name.

Following Gabi’s trail, Klara comes face-to-face with Jacob, as well as with George Lööw, a suave lobbyist from her past to whom she finds herself inexorably drawn. Now Klara, George, and Jacob set off on a race across Europe to stop a pending terrorist attack—and get to the bottom of Yassim’s true identity.
