Slim pickings here, I'm afraid. The top books on both LibraryThing and GoodReads which are set are two different non-fiction accounts of the same set of events, an organisation of Jewish partisans who fought against the Nazis from the Naboliki forest. One of the books was adapted for the cinema, the film starring Daniel Craig. The two books are:
Defiance (1993) by Nechama Tec (top on LT, film released in 2009), and
The Bielski Brothers (2004), by Peter Duffy (top on GR)
Some way behind is a novel about the Stalinist occupation of a village in the Pinsk marshes, published in :
Wave of Terror, by Theodore Odrach
The top novel by a Belarusian writer writing in Belarusian is a tale of a folkorist visitng an isolated castle, confronted with an ancient family curse. It is:
King Stakh's Wild hunt / Дзікае паляванне караля Стаха, by Uladzimir Karatkevich
Also worthy of note, on LibraryThing a collection of poetry by a Belarusian resident in America has attracted some attention, published in a bilingual English/Belarusin edition in 2008. It is:
Factory of Tears / Фабрыка слёз, by Valzhyna Mort.
