Between Shades of Gray by Ruta Sepetys
In the blink of an eye, Lina finds her life forever changed when Soviet guards tear her family from their Lithuanian home during World War tensions. With no knowledge of her father's whereabouts, Lina, along with her mother and younger brother, struggle to survive through starvation, illness, exhaustion, and the harshest conditions.
Not for the faint of heart, this gripping story is based on a true (and often untold) history, which Author Ruta Sepetys has uncovered from her own family's past. Haunting!
