See here for methodology. My rule is to exclude books of which less than 50%, as far as I can tell, is actually set in the target country, but for Ukraine this is trickier than in some cases, so I may have made a couple of wrong calls here.

Title	Author	Goodreads raters	LibraryThing owners
Everything is Illuminated	Jonathan Safran Foer	181,991	14,539
The Mitten	Jan Brett	93,416	10,761
The Diamond Eye	Kate Quinn	170,157	1,425
Midnight in Chernobyl: The Untold Story of the World’s Greatest Nuclear Disaster	Adam Higginbotham	57,625	2,324
Death and the Penguin	Andrey Kurkov	20,056	2,116
The Last Green Valley	Mark T. Sullivan	65,498	431
The Fixer	Bernard Malamud	11,675	2,374
The White Guard	Mikhail Bulgakov	15,452	1,528

Shamefully, I have not read any of these. When I looked at this less systematically back in 2015, I got the same answer, Everything is Illuminated way out in front, followed by Jan Brett’s version of The Mitten.

I excluded The Master and Margarita, by Mikhail Bulgakov, which is definitely set in Russia; Dead Souls, by Nikolai Gogol, which is generally understood to be set in Russia; A Short History of Tractors in Ukrainian, by Marina Lewycka, which is set in England; Voices from Chernobyl, by Svetlana Alexievich, which is about the impact of Chernobyl in Belarus; and Bloodlands, by Timothy Snyder, which as far as I can tell concentrates on Poland.

I’m not 100% sure about The Last Green Valley, which is about Volksdeutsche fleeing Ukraine at the end of the Second World War, but it seems from online sources that it takes them a long time to get out, so I’ve counted it in.

The top Ukrainian writers on the list are Andrey Kurkov and Mikhail Bulgakov.

The Diamond Eye and The Last Green Valley both have strikingly impressive Goodreads ratings compared to their LibraryThing standing. Usually books have around ten times more readers on GR than LT, give or take; these two score over a hundred times higher on GR. My interpretation is that they (successfully) marketed themselves to Goodreads users.
