This has already been much-read and much-discussed; I delayed reading it because it sounded so sad. But lately I was, uh, in the mood to wallow around in some sadness, and this definitely fit the bill. It's also beautifully written and a window into a rarely-discussed (in the US anyway) historical tragedy; I had no idea that Lithuanian (and citizens of other nations) were kept by in Russian forced labor camps well past the end of WWII.

PS although this book is hella sad it does also end on a hopeful note due to the historical framing device, whew
