The Chaperone by Laura Moriarty. I read the book in one sitting, staying up until 4am when I really needed my sleep! It is the fictional story of a woman who chaperones a 15 year old Louise Brooks to New York in 1922, and how it alters the course of her life. I found the narrative compelling, and would recommend it to anyone who enjoys a good story set within the context of real events. The book also made me interested in learning more about Louise Brooks, a complex and difficult silent film star who became a film writer in later life. I highly recommend giving this one a try!
