I don't even know how to begin reviewing this book, so I'll just say that it's so good, so well written that I'm reading through the whole series. If you love stories of war, strong male warriors mixed with some humor then you'll like these books by Cornwell. I watched the BBC TV series before reading these books and of course the two don't line up my perfectly, but so what. They never do so don't expect it. It was good to watch it first to give you a good picture in your mind of the words in the book. As mentioned in other reviews, the violence is graphic. War is a very unpleasant thing.
The author is very clear on what parts of the book are based on his researched historical documents and what parts he took artistic liberty with.
