Per Petterson 
To Siberia [EPUB ebook] 

In the bitter cold of Danish Jutland, where the sea freezes over and the Nazis have yet to invade, a young girl dreams of one day going on a great journey to Siberia, while her beloved brother Jesper yearns for the warmer climes of Morocco. Their home, with a pious mother who sings hymns all day and a silent father, is as cold as their surroundings. But the unshakeable bond between brother and sister creates a vital warmth which glows in spite of the chill and the dark clouds that threaten to overtake their dreams.
