Query: Informative & historical, but not very enjoyable to read.

I read the book because I had seen the miniseries on TV and was interested in more information. It included a lot of facts and was interesting from an historical perspective. However, I didn't think it was particularly well written from a literary perspective. It was also hard to follow because it jumped around. It included a lot of information that was interesting, but not directly related to the subject. Sometimes it seemed like it went off on tangents. Overall I would rate it average, it was informative, but not very enjoyable to read.
