My first criticism of this book is the strong bias against Anne, who is definitely treated as the villainess of the Glorious Revolution. Another major problem is that sometimes the author gives her opinion as historical fact. A prime example is whether William of Orange always intended to make himself king. The Dutch historian Wout Troost in "William III, the Stadholder-King" acknowledges that historians are divided on the issue before giving his opinion that what William wanted was "to neutralize James II as a potential ally of France, but it was by no means necessary to depose him to achieve this." Ms Waller, however, makes no reference to the fact that there are differing views and presents her opinion as fact.
Finally, when I read this sentence I had to laugh aloud: "The fact that Mary never ceased to hope for a child, as she confided in her journal, might be attributed to her ignorance and innocence." It was of critical importance that Mary produce Protestant heirs to the throne so the idea that no one would've told her how to go about it and she was too innocent or too ignorant to know that she and William had to do more than sleep in the same bed to conceive a child is the silliest theory I've ever read. I personally favor the suggestion of historian and medical doctor, Frederick Holmes, in "The Sickly Stuarts" that either William or Mary or both had relatively low fertility. The fact that they were first cousins increased the chance of genetic abnormality resulting in a miscarriage. Mary definitely had a miscarriage five months after she and William married.
Because the bias against Anne is so extreme and because the author confuses opinion with fact, I hesitate to recommend this book.
