Although there is nothing wrong with this book, I didn't found the narrative compelling. With the so-called "historical novels", there are the ones that strive to focus more on the "factual" events and the ones that choose to favour the drama. This book wasn't historically very detailed but at the same time lacked a lot in drama. The events simply happened, almost from nowhere.
Although it is not a book I regret to have bought, the author does not seem to be at the level of Bernard Cornwell or Conn Iggulden.
