The Way Past Winter | Kiran Millwood Hargrave
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.
