I'm currently reading an excellent and engaging book called Murder in Matera by Helene Stapinski. I stumbled upon this book in the midst of my research, when I discovered an article she wrote in the New York Times entitled "When America Barred Italians".
Check out the article; if you find it as intriguing as did, I recommend her book as well.
UPDATE: I ended up listening to this book via audio while I was driving the long road from Naples to Palermo just a few weeks later. So inspiring! I learned a great deal and still highly recommend the book!
