She's ready to upend the rigid Order of the Guardians, whether the older members like it or not. And in a Society where magic is the greatest scandal of all, Kat is determined to use her powers to help her two older sisters find their own true loves, even if she has to turn highwayman, battle wild magic, and confront real ghosts along the way! History seamlessly merges with fantasy in this humorous and lively novel.
