Two strangers find themselves connected by a vast and mysterious library containing many wonders and still more secrets, in this powerfully moving first book in a new series from the international bestselling author of Red Sister and Prince of Thorns. The boy has lived his whole life trapped within a book-choked chamber older than empires and larger than cities. The girl has spent hers in a tiny settlement out on the Dust, where nightmares stalk and no one goes. The world has never even noticed them. That´s about to change. Their stories spiral around each other, across worlds and time. This is a tale of truth and lies and hearts, and the blurring of one into another. A journey on which knowledge erodes certainty and on which, though the pen may be mightier than the sword, blood will be spilled and cities burned.
