This book is really really good! Set in Victorian England, its vocabulary is wide - it would probably be handy for younger readers to have a dictionary nearby! The plot is great, a story about Sophronia Temminick, a unique heroine sent to a school for assassins. Gadgets, robots and the act of tucking your handkerchief in your corset, are all some of the things that make this book what it is - Simply Brilliant!!
