This took a little effort, sometimes, but it was good. I'm always fascinated by the major historical turns that happen (or don't) just based on this or that individual's choices, or health, or what have you. I'll also never consider the differences between the Catholic church (that my wife was raised in) and Protestantism (that I was raised in, and she switched to) quite the same way again. We've each had some slightly awkward church services, but never been worried about being hanged, drawn, and quartered over it. Speaking of which, the breathtaking brutality of the age was shocking, too.
The author has a clear distillation of Elizabeth that he drums in more and more, right to the end (spoiler? nah): that she was indecisive to a fault. And maybe she was, but I finished this book thinking that it would be interesting to see if other biographers homed in on that point so relentlessly. That said, to be honest, I'm not sure I'll have the energy to wade through all these names, dates, battles, etc. again any time too soon.
So, it wasn't a page-turner, but what nonfiction biography of a 16th-century ruler would be? It was well-written, and had enough of a dose of an editorial point to not be too dry; I recommend it, if you're interested in the subject.
