Alexievich won with "Secondhand Time", which I absolutely loved. It is essentially a transcribed oral history, but composed in such a way so as to become literature. It is particularly admirable for the way in which it allows narratives which contradict each other to stand in adjacent chapters, which is jarring, but also very honest.
Please read it if you have the patience for hard reading and some deeply sad stories.
>Alexievich echoed Korolenko by claiming three homelands: her mother’s Ukraine, her father’s Belarus, and—“Russia’s great culture, without which I cannot imagine myself.” By culture she meant, above all, literature.
