Query: Captivating

Here is a book I thoroughly enjoyed from beginning to end. It was like living around the year 1000 and being taken on a tour around so you could see how different things were at that time. For example, I learned why the postal system in Europe uses the posthorn as its symbol. I learned where cruelty to children stems from. I learned why caravans were popular. I came to realize more fully why decent women prostituted themselves. And I learned much, much more from being carried back into that time about 1000 years ago. I wished the book just went on and on.
