Seventeen-year-old Lumikki Andersson is hardly your average teenager. She lives by herself in the city of Tampere, Finland, and has a firm rule to mind nobody’s business but her own. But that rule is put to the test once Lumikki realises who owns them. Caught in an increasingly tangled web of deception, corruption and danger, Lumikki finds herself navigating Tampere’s dark underbelly in her quest to expose its shocking connection to the international drugs trade. Lumikki is smart, but is she smarter than a master criminal? Can she bring down the infamous ‘Polar Bear’ - or will she become another one of his victims?
