A covert mission A royal demand And a race against time The fourth title in Genevieve Cogman s witty and wonderful The Invisible Library series, The Lost Plot is an action-packed literary adventure! In a 1930s-esque Chicago, Prohibition is in force, fedoras, flapper dresses and tommyguns are in fashion, and intrigue is afoot. Intrepid Librarians Irene and Kai find themselves in a race against time (and dragons) to procure a rare book whose discovery could have serious political repercussions for Kai s people - and whose loss could have dire consequences for Irene s job. And, incidentally, for her life . . .
