wo strangers find themselves connected by a mysterious and vast library, which contains many wonders and even more secrets, in the powerfully moving first book in a new series from the international bestselling author of Red Sister and Prince of Thorns, now in trade paperback.

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.
