International No.1 bestselling author Trudi Canavan returns with her most powerful and thrilling adventure yet. In a world where an industrial revolution is powered by magic, Tyen, a student of archaeology, unearths a sentient book called Vella. Once a young sorcerer-bookbinder, Vella was transformed into a useful tool 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 the dyer's daughter has been taught that to use magic is to steal from the Angels. Yet she knows she has a talent for it, and that there is a corrupter in the city willing to teach her how to use it - should she dare to risk the Angels' wrath.
