The year is 1942, and Norway is under Nazi occupation. Twelve-year-old Marit has decided to take action, despite her grandfather's warnings. But will her plan work? Can she really complete her part of this secret code? And even if she can, would it make any difference to the Resistance?

As this novel reveals what Norwegian people did to preserve their dignity and freedoms, it uncovers a startling statistic: the German secret police systematically rounded up one teacher in ten and sent them to concentration camps for their refusal to teach Nazi propaganda to Norwegian schoolchildren. Set on an island of sturdy fishing trawlers and brightly painted homes, with smells of kelp and salt water, here is a riveting novel about risks taken, secrets kept, and, always, questions about whom to trust.
