Do you just want reading recommendations or are you looking for someone here to give an explanation?

For the moment, I'll just answer the former, though I'll happily give an overview myself if you want, just let me know!

• Steven Burg and Paul Shoup, The War in Bosnia-Herzegovina - in my opinion, the best general overview of the conflict.
• Valere Gagnon, The Myth of Ethnic War - seeks to destroy the idea that the war was brought about by intractable ethnic tensions, though probably requires a basic level of familiarity with the events to fully understand and appreciate.
• Susan Woodward, Balkan Tragedy - Decent overview focusing on the international and geopolitical dimensions, but with a pro-Serb bias. Some have gone as far as accusing Woodward of being an apologist for Serb nationalist war crimes, but in my opinion that's quite unfair on her.
• Sabrina Ramet, Balkan Babel - the opposite problem to Woodward. Gives an overview of events, but is too normatively anti-Serb to provide much good analysis.
• Gerald Toal and Carl Dahlman, Bosnia Remade - focuses on the infamous ethnic cleansing in the wars.
• BBC, The Death of Yugoslavia documentary - excellent overview of events, something I would definitely recommend as an introduction to the conflict, though it was made in 1995, and so lacks a lot of the information that has come out in the two decades since, most notably the trials.
