Yasmine Ajam has fled her past in the rough Stockholm borough of Bergort, reinventing herself as a trendspotter in New York City. One day she receives a startling message: there are riots erupting on the streets of Stockholm, and they appear to be connected to the disappearance of her brother, Fadi. Following rumors that Fadi was radicalized and died fighting for ISIS in Syria, Yasmine returns to Stockholm to discover what really happened to her brother. There she becomes entangled in a dangerous web of allegiances and violence that stretches far beyond the gangs on her childhood streets.

Meanwhile, in London, Klara Walldéen has landed a job at a human rights research institute working on a report to predict the effects of privatizing police forces. When Klara travels to Stockholm to present her findings to European Union policymakers, her laptop is stolen and one of her colleagues is pushed in front of an oncoming subway train. As her path collides with Yasmine’s, Klara begins to realize that she may unwittingly be contributing to the sinister agendas of powerful interests who will stop at nothing to attain their goals.
