Ravenna looks very interesting! I will get a copy.
I saw the reviews on Amazon. I must buy the book. RE: Carl Zimmer - A Planet Of Viruses.
Ravenna has been a good read - amazing how complicated the post-Roman Empire was when the Byzantine Empire flourish w/ Justinian - back in 1996, I was invited to speak at a medical meeting in Bologna; we had a day free, so wife and I took a train to Ravenna - was like entering another world, and the architecture, mosaics, etc. were just gorgeous. The book and pics within will likely stimulate some at least to want to visit.
A Planet of Viruses by Zimmer - read an early edition - the 3rd edition will be released April 1 so should have much on the COVID pandemic - will likely purchase a Kindle app edition for my iPad. In hardback, currently reading
The Plague Cycle, published this year which covers infectious disease in general, so far quite good. Dave
