In between shades of gray who is the main character

 a New York Times Bestseller, is the debut novel of American novelist Ruta Sepetys. It follows the Stalinist repressions of the mid-20th century and follows the life of Lina as she is deported from her native Lithuania with her mother and younger brother and the journey they take to a labor-camp in Siberia.

She befriends many people and works hard alongside her mother and brother for food and survival.
