I think this book is great story for people who like mystery, magic, and fanasty. This book takes place in the1800's, in a neighborhood in London. In the story you might read of the Order, Keepers, Greymalkins and more. All of them have magical powers. Some use them for good, some don't. I liked this book because it has magic, adventure, and lots of excitement.
