I went back and forth on whether this was a two or three star rating for me. The beginning of the book is nicely written drawing the reader into the story as seen through the eyes of a very young Juana. The middle however started to become much too modernized for my personal taste. I felt like the author's writing was too forced and just didn't flow well. Some of the thoughts attributed to Juana were just too contrived and what I felt would have been unrealistic for a Queen of that time period.
At the end of the book I once again was engaged in the story as Juana was viciously manipulated by her husband, her mother's advisors and finally by her father. The tragic end was heartbreaking. I also enjoyed the author's commentary as to what was true regarding Juana and what he had created.
