If you enjoy reading about a part of world history that you are very likely completely unfamiliar with, I definitely recommend this book. The story is of a teenage girl, who, along with her family, is rounded up from her home in Lithuania in the early days of World War II, and sent to concentration camps in Siberia. This is a time in history when Josef Stalin started taking over the Baltic States of Estonia, Latvia, and Lithuania, essentially erasing them from the map, not to emerge again until the break up of the Soviet Union in 1990-1991. It's a sad story, so keep some tissues handy, but ultimately a hopeful one.
The movie based on the book is coming out sometime this year, but its title is "Ashes in the Snow," likely to keep from being confused with that other "Shades of Grey" movie.
