I read this as one of the picks for the Litsy (Team YA) Postal Book Club I am in, and am glad it was chosen, even though I often do not choose historical fiction much these days to read. Especially when I expect it to bring me to tears (or remind me how little I know about how the Soviets and Stalin played their dastardly part in WWII).
Given that this book is several years old now, has won countless awards, and it seems as though everyone else who reads YA has already read it, I barely need to say much about the premise.
Young Lina is deported by the Soviets from Lithuania, along with her brother and mother, but her father gets separated from them to elsewhere in Eastern Europe. The book tells of their long long train ride bringing them to outer Siberia and the horrific trials that her family and other deportees go through. They are emblematic of a past that has been covered up and forgotten among war stories, probably due to so many other horrors (particularly due to Hitler, the Nazis, and the Holocaust).
What Sepetys has written here though, is very relatable account, that I think many younger readers will be drawn to, and have been already; Lina develops a relationship with a teenage boy while deported, has the regular range of emotions you would expect from a teenager, and her love for her family, especially her missing Papa, is fierce.
And while I did not expect the full horrific descriptions I might see in an adult novel on this matter (for example, deaths, burials, etc.), there is enough here to make the reader feel angry, revolted, and incredibly heartbroken at many things that went on.
Since this novel is based on actual people and events (and Sepetys mentions the research and journeys she went on at the end), it is especially thought-provoking and meaningful. There were so very many people affected by the first and second world wars, particularly across Europe, I can hardly imagine how many individual stories like this exist. At least go and read one of them and remember what happened.
