The Unladylike Adventures of Kat Stephenson: Book One, A Most Improper Magick by Stephanie Burgis (Published by Simon & Schuster, April 20, 2010)
In nineteenth-century England, twelve-year-old Kat Stephenson knows she was born to be a magical Guardian and protector of Society—if she can find true acceptance in the secret order that expelled her mother. 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.
This is another Tenners book, and I think it sounds great! I love the combination of history and magic. And I think the cover is just adorable!
