This book is a terrific ending to the Constantinople arc. Cannot recommend it strongly enough to all who like the company of archers series. Consulting online maps and pictures helped me appreciate some elements of the story.
I couldn't put it down, read it all the way through in one day. It's a great book with a surprise ending. I think they ought to make this into a television series. Now I am going to go back and re-read the entire series from the beginning!
