The White Queen
I first listened to this novel (about Elizabeth Woodville, queen consort of Edward IV) as an abridged audiobook early in the year and was disappointed. The abridged version showed little of the York court, concentrating on Elizabeth's times in sanctuary during the wars and Lancastrian restoration. It also expunged references to Edward's unfaithfulness, a thing that would have doubtless been sometimes on Elizabeth's mind, even if she tolerated it. However, skimming through the hardback book, I found that these elements were indeed there. I still wouldn't call it a favorite; I didn't connect with the portrayal of Elizabeth's personality. That said, Gregory should be commended for writing a decently sympathetic portrait of the woman who was - and in historical fiction (such as The Sunne in Splendour) still seems to be - the reviled Wallis Simpson of her age. As with her novel about Elizabeth's mother, Jacquetta of Luxembourg, Gregory portrays women as using forbidden herbalism and magic to gain their own form of power in a man's world.
The Red Queen
The Kingmaker's Daughter
This novel - centering on the life of Anne Neville, queen consort of Richard III - was rather uneven. It had some wonderful moments showing the absolute horror and danger of childbirth in late Medieval times. Anne's relationship with her sister Isabel was depicted as close and complex. However, I never really felt like Anne's character was well defined. Especially confusing was how quickly she became loyal to her formerly-feared mother-in-law, Margaret d'Angou. Richard (yes, of course that's who we're really interested in) is quite well-drawn. Gregory doesn't come across as a raving Ricardian or a Shakespearean hater. Her Richard can be kind or ruthless, simultaneously charismatic and calculating.
While Gregory isn't a very highbrow author, I probably will pick up the other books in the series when I see them at the library. Of course I'm already raising my eyebrows at the premise of her new book on Princess Elizabeth of York. SPOILERS FOLLOW which appears to be that Elizabeth and Richard III were lovers. It is, of course, not an unprecedented idea and it's hardly surprising that it was the route Gregory chose to take. She is certainly never one to miss out on the most sensational interpretation.
