In my latest "What We're Reading" column for NoveList, a readers' advisory database for public and school libraries, one of the novels I highlighted was Fiona Avery's The Crown Rose. It's a historical fantasy novel about Isabelle, Princess of France, the younger sister of Louis IX who was later canonized (as was he). I won't give a formal review here since the column won't be out until June, other than to say that for "What We're Reading," I only cover novels that I enjoy. But you can read the description and reviews on Amazon.
You can also read more about St. Isabelle at the public domain Catholic Encyclopedia, although since Crown Rose is a historical fantasy, the novel diverges from her actual life story in unique ways.
The dust jacket copy begins as follows: "The Crown Rose tells the story of Isabelle of France, born heir to the throne: her life from childhood to her later years; a life of turmoil and strife and longing...."
Right away, I wondered if whoever wrote this blurb read the book, or even showed the blurb to the author in advance of publication, because it makes you wonder if the author knows anything about French history. Isabelle was not born heir to the throne; in 1240, when the novel begins, she not only has two older brothers, Robert and Alphonse, in addition to King Louis, but she also has a younger brother, Charles. And if I'm not mistaken, the Salic law was operating during that time, as it did for most of French history, so women could not inherit at all.
Anyway, it's not the author's mistake, and this is clear after you read the book. But nonetheless, on Amazon you'll find reviews in Publishers Weekly, the Midwest Book Review, and from Klausner repeating the same "heir to the throne" bit. Curious.
