I didn't finish it, but I readily admit that it compels one to keep reading. It simply seemed that descriptions and events were kept deliberately muted, to compel one to build hopes and expectation that conflict was impending. The descriptions of sniper preparations are are also done with entirely too much loving, technocratic detail.
Finally, the Balkans as a centre of conflict has a long, complex history. A genuine attempt to portray the complexity of those emotions, ethnically, etc., would have been a far deeper experience, even if it's a plot with no easy endings.
