What I liked about this book was the way the author sits down with you and very honestly says: Look, here are the facts as well as we can possibly know, and the rest I made up. The story may not be exactly true, but something like this must have happened. Perhaps not Robert Harris's best book: it contains lenghty descriptions of actual battles on British soil. Also, I haven't counted the Puritan church services described, but it seems as if there were several Sundays a week in those days. The end, while long expected, seems written in a bit of haste. That said, even an average Robert Harris book is still a good book.
