In The Virgin's Lover, Gregory moves us forward from Henry VIII's reign, past Edward's and Mary's, and into Elizabeth's. (If you want to read them "in order," The Queen's Fool comes prior to The Virgin's Lover.) The story is not told from the view point of Elizabeth, but one of her lovers, Robert Dudley, as well as his wife Amy. It's interesting to read from this perspective as one can see the abandoned wife and identify with her pain. It's also interesting to see Robert's guilt, yet how he still chooses to continue on with his affair. If you're into historical fiction, this novel gives an interesting insight into Elizabeth's life and is worth the read.
Now, Gregory enters into a little bit of speculation, since most folks, obviously, didn't document their own affairs. But Gregory is great at doing her own research and including an author's note to let your know where and why she made speculations or changes to history. It really makes me respect her as an author.
