I was hoping to look more into the period and was wondering if someone could recommend a good book or two that would provide a good overview of the subject.
1177 BC: The Year Civilization Collapsed by Eric H Kline
The graduate seminar I took on this used Drews, The End of the Bronze Age. Drews presents and evaluates the evidence for a number of different theories (12?) ranging from systems collapse to earthquakes to climate change to invasion. In the end he settles on technological innovations that allowed mass infantry to successfully confront chariot armies.
I'm not entirely convinced, but it's a good argument.
