I am half way through that (Henry VIII). I love that series and have been picking my way through it for years now. When I bought them, I thought I would read one a year. With all my other reading, it takes about two to get through a volume. They are wonderful though. There is truly nothing new under the sun!
The Henry VIII was my fave chapter, along with the science in the time of Copernicus chapter. I usually average a book a week; this one took me two months. I thought I was well-versed in history until I read it! :) Now I'm hooked and need to pick up the other volumes.
