Durham, 1874. In a world where anything can be written in or out of history, nothing is as it seems... When Caira Dobbin is handed a mysterious note by a stranger, it leads her to Tsundoku - the keeper of the books - and to a secret library set deep underground in the heart of the city. She hopes that somewhere, in amongst the vast collection of books and articles, she’ll be able to find clues that will lead her to The Book of Life - the only book that can erase The Paper Queen from history and restore order to the city. Caira and her uncle, Myrin Peacock, embark on a perilous voyage to The Isle of Lindisfarne to recover the book, but the lines between reality and paper start to blur, and Caira doesn’t know who she can trust...
