Yutu lives in a remote, Arctic village with his elderly grandmother. Their traditional way of life is threatened by the changing snow and ice, which melts faster every year. Bea is trying to adapt to yet another new school. Worse still, her father's new job takes up any spare time, and his behaviour has become odd and secretive. On a trip she hopes will fix things, their fates take a drastic turn and Bea's life becomes entwined with Yutu's in a way she could never have imagined. Together, they become locked in a desperate race for survival.
