This is a book that has been a long time coming. The atrocities of Nazi Germany are well known, mostly because they are so well-covered in popular culture. I have found that few people actually know much of anything about what Stalin wrought in his own country and the neighboring ones gobble up to be a part of the USSR. Sepetys' may be the first to cover this topic for a teenage audience. Hopefully more will follow.
The story certainly calls to mind the Holocaust stories that preceded it, but Sepetys does a good job of pointing out the differences between the enslavement/incarceration in Germany and in the Soviet Union. Between Shades of Gray is not an uplifting book, although it is intended to inspire its reader to consider the nature of good and evil. The epilogue, which I am of two minds about, clearly states the author's mission for the book, which is a good one, but is perhaps a bit too forceful when stated directly.
My only concern is whether Between Shades of Gray is dark enough. I read Solzhenitsyn's The Gulag Archipelago in its entirety, so I have a decent understanding of the Soviet prisons. However, Lina is not in one of the prisons and I know less about the camps like she lives in. Lina's family seems overall to be spectacularly lucky. One illustration of this: Lina, in a very stupid move, draws pictures of pretty much everything that happens to her family and hides them, and not very cleverly. Somehow, though, she does not get caught. I kept expecting her to, as so many people went down for such things in the Soviet Union.
I do not intend this as a definitive criticism, solely as a question to consider, and I would be interested in hearing the opinions of others. My only real basis for comparison is Solzhenitsyn, who was writing for adults and to show the Soviet system at its worst. Whether it is a bit lighter than reality or not, Sepetys has written a wonderful and crucial book for teens.
Look for Between Shades of Gray in stores this March! This is one you shouldn't miss.
