Books about Italy

I am going to Italy next week and I’m looking for a book about Italy. When I travel I like to read about where I’m going. For example I read the count of monte Christo when I went to Paris years ago. I’d rather a non fiction book. I have read Dante’s inferno, and a biography about da vinci but need another one.

I'd prefer books on Rome, Venice, Florence, or the Amalfi coast, but I'll look into all the suggestions. Thanks
