Not a book, but BBC's Death of Yugoslavia documentary is pretty good. It's mostly impartial and has interviews by most major players of that time. I promised a redditor my review something like two years ago and still didn't write it. Sorry guy.

Not a history, but I enjoyed reading My War Gone by, I Miss it so. An autobiography by a journalist about his time in the Balkans and his heroine addiction.

I am currently reading Madame Prosecutor: Confrontations with Humanity's Worst Criminals and the Culture of Impunity by Carla Del Ponte, Chief Prosecutor of the tribunal that was set up to try the war criminals of the Yugoslavian conflict (from 1999-2007). I would not recommend it as an introduction to the Balkans conflict at all, but I would nevertheless recommend reading it if you do have an interest in the Balkans conflict because it gives a fantastic insight into the politics of time, and through such a lot of information can be gained. International Justice in Rwanda and the Balkans (by Victor Peskin) and Stay the Hand of Vengeance (by Gary Jonathan Bass) also have a focus on the tribunal (and the political maneuverings of the US, NATO, Serbia, and Croatia) rather the conflict in general but if you do have an interest in the conflict from a political perspective you may find interest in them.

I apologise for not being able to give a book suggestion based more on the history of the conflict itself (as a law student my knowledge of the conflict comes from a legal and political perspective of the tribunal). However, though it did not receive many replies, a similar question was asked a year ago so the few book suggestions there may be useful. This thread also has the recommendation of the book Yugoslavia: A State That Withered Away.
