Mila and her sisters live with their brother Oskar in a small forest cabin in the snow. One night, a fur-clad stranger arrives seeking shelter for himself and his men. But by the next morning, they’ve gone – taking Oskar with them. Fearful for his safety, Mila and her sisters set out to bring Oskar back – even it means going north, crossing frozen wild-lands to find a way past an eternal winter. The gorgeous new novel from the bestselling author of the Waterstones Children’s Book Prize-winning The Girl of Ink & Stars and the Costa and Blue Peter Award-shortlisted The Island at the End of Everything.
