The book's narration comes from several shifting POV's (primarily Mary), as well as some third-person narrator comments. The narrator's are really what makes this book so special. They are absolutely hilarious, providing a 'so-here-is-the-scoop' tone. They are terrible gossips, but charmingly witty at the same time. They are that friend in college/high school that you always turned to when you wanted to hear about the latest scandals without going through the effort of snooping things out for yourself. Before the book even properly started I was cry-laughing at the dedication: "For the people who feel like they have to be perfect; and for France. We're sorry for what we're about to do to your history, but it was your turn."
On top of the comedy, the characters were so well developed. I truly felt for Mary and Francis, and even the side characters like Mary Livingston and Ari. Their actions and motivations felt real, and the stakes and betrayals in court were gutting. While of course this is a series of Marys, in a sense each book is also a stand alone, which I think is a boon to the work. Readers don't necessarily have to read The Lady Janies series to enjoy this latest work. Comedy and Historical Fiction blend together effortlessly in this gem of a book. Bonus points? Bonus points! On top of everything, I actually feel like I learned a lot reading this book. The plot was surprisingly historically accurate, if we overlook the whole fantasy shapeshifting element haha.
All in all, My Contrary Mary is a must-read, and I impatiently await the additions of Mary Shelley and Mary Read to the new Mary series!
