I found this a most annoying book. It combines some fact with a lot of fabrication. While historical fiction necessarily employs imagination to develop dialogue, describe meetings etc. and while questions about Elizabeth's personal life and complex personality give ample opportunities for invention in describing her court and those surrounding her, this book sets forth implausible events as well as situations that are in direct contradiction to historical evidence. It also makes many unwarranted assertions about various people. In the process, it trivializes fascinating characters and tells a much less compelling story than what is on the record. If the reader is interested in Lettice Knollys and her family, he/she would be better off reading "The Lady Penelope" by Sally Varlow, which tells the real story, insofar as it can be ascertained, in a far more satisfactory manner. Above all, the reader of "Rival to the Queen" should not approach it as an accurate reflection of events or characters, but simply a novel.
