In a 1930s-esque Chicago, Prohibition is in force, fedoras, flapper dresses and tommy guns are in fashion, and intrigue is afoot. Intrepid Librarians Irene and Kai find themselves caught in the middle of a dragon vs dragon contest. It seems a young librarian has become tangled in this conflict, and if they can't extricate him there could be serious political repercussions for the mysterious Library... Perfect for fans of Ben Aaronovitch, Jasper Fforde or Doctor Who!
