This is a popular history book in tone and content. More emphasis on drama, less concern with details, historical context, or accuracy. Sadly, this is the case for a lot of popular history books.
I listened to it as an audio book, and it was an easy way to kill a few hours, so I guess it works on that level. If you want something that is historically sound, I personally recommend actual scholars on the subject who are acquainted with the historical period, documentation, and current historiography. Or conversely, if you are looking for something fun about early modern England, I always recommend the Wolf Hall series.
