I had not read much at all about the siege of Sarajevo that occurred from 1992-1996 which was part of the Bosnian War.  I got a small glimpse of what that time period was like in Sarajevo through Zora, a Bosnian Serb artist living in Sarajevo at the time.  The book started out slow for me but then picked up until the very end. For me, I think once I read the reference to what black butterflies were, I just got swept into the story.  There aren't chapters - more like 5 sections which makes it challenging to go between audiobook and physical reading. I'd recommend this one in print.
