International No. 1 bestselling author Trudi Canavan returns with her most powerful and thrilling adventure yet. In a world where magic powers an industrial revolution, Tyen, a student of archaeology, unearths a sentient book called Vella. Once a young sorcerer-bookbinder, Vella was transformed by one of the greatest sorcerers of history. Since then she has been collecting information, including a vital clue to the disaster Tyen's world faces. Elsewhere, in a land ruled by the priests, Rielle has been taught that to use magic is to steal from the Angels. Yet she knows she has a talent for it, and that a corrupter is willing to teach her - should she dare to risk the Angels' wrath. But not everything is as Tyen and Rielle have been raised to believe. Not the nature of magic - and not even the people they trust. Escape to a new world. Discover the magic of Trudi Canavan.
