I just finished reading "Chernobyl Prayer" by Svetlana Alexievich It's a book made up of interviews with people who lived through Chernobyl and its aftermath. It's probably the most heartbreaking book I have ever read. I can't recommend it enough to anyone who wants to understand the human cost of Chernobyl on an intimate, deeply personal level.
Here you go!
I bought the kindle edition but it is available in paperback too :)
