Time to again plug Eric H. Cline’s “1177 BC, The Year Civilization Collapsed”
He analyzes a lot of theories linking the Sea Peoples to various destruction sites, though mostly shows how we lack evidence for who caused said destruction in almost every case. I’m still reading it, but quite like it.
Great book! It doesn't offer any easy answers, but it does a great job of showing how complex the situation was. It's also a great look at how interconnected the bronze age was.
