Apparently the longest of the "Concise History" series, "A Concise History of Serbia" is also one of the best book in the series (in part because of it being the longest!). It covers the medieval and early modern/modern periods more evenly than other books in the series, which is particularly important given how dynamic the history of medieval Serbia really was (sadly, I'm having a hard time finding a book that does medieval Bulgaria justice) and how important older history is to understanding more recent events.
Mildly pro-Serbian but not excessively so, Djokić covers the history of Serbia in relationship to its neighbors, including the Byzantines, the Ottomans, the Croats, and the Bosnians. It also touches on cultural aspects (especially in the more modern history). Importantly, the book helps to explains how, in spite of the 1990s wars, Serbians see themselves as victims - because, for much of their history, they actually were - from the Ottoman period, the 1800 uprisings against the Ottomans, the World War II Ustaše atrocities, etc.
I've recently read three books about three of the former Yugoslav countries - Croatia, Bosnia, and Serbia - and this was the best of them all (though, best of all was really reading all three books together). One of the things I appreciated about this book was how it made Yugoslavism (South Slavism) make more sense. As the author explains it, the Germans and the Italians both united into one nation, so it wasn't a stretch to think that the Serbs, Croats, and Bosnians (who all speak more or less the same language, though they might not all see it that way) could do so too. And indeed they did.
The one aspect of Serbian and Yugoslav history I would have wished for better coverage of was the reasons why Yugoslavia fell apart. There is no real analysis of this other than the history of the events, the author instead referring to the literature on this question in a footnote on page 478. Obviously, one can come away with some tentative conclusions based on the history provided, but it would have been nice to have had more analysis on this question. How exactly did the confluence of different factors - the contest between elites within a federal system, the historical memory of atrocities, the evolution of constitutional structures, the importance of ethnic and religious identities, the weaknesses of communism, the ideology of nationalism, the international and European state system, and perhaps other factors not mentioned here - lead to Yugoslavism being unsuccessful rather than something that endured? Perhaps it was the more multinational (contra unitary) nature of Yugoslavism in an age of nation-states that made its breakup most possible, but that is a partial and tentative conclusion only and one that I would like to revisit in the future.
(P.S. Or maybe the question should be flipped - instead of, why did Yugoslavia disintegrate, what was it about the origins of Yugoslavism that made it different from the origins of German and Italian nationalisms? And did that difference/those differences make the disintegration of Yugoslavia more likely? Yugoslavia was, after all, created by different peoples more voluntarily than Germany or Italy were. Perhaps unification by domination + less ethnic and religious diversity + more unitary governance vs. more voluntary federalism by different actors made the difference...).
