Not all fairy tales end happily ever after in this Cinderella-inspired fantasy by the bestselling author of Daughter of the Moon Goddess--for fans of Renée Ahdieh, Tahereh Mafi, and Stephanie Garber.

Life in the Iron Mountains is harsh and unforgiving. After the death of her beloved uncle, Yining has survived by becoming a skilled thief and an even better liar. When she acquires an enchanted ring that holds the key to a new life, it is stolen by her grasping step-aunt, and Yining must venture into the imperial heart of the kingdom to seize it back.

Amid the grandeur of the palace, Yining catches the eye of the ruthless and ambitious prince, who tempts her with a world she's never imagined. But nothing is as it seems, for she's soon trapped in a tangle of power, treachery, and greed--her only ally the cunning advisor from a rival court who keeps dangerous secrets of his own. To break free, she must unravel the mystery of her past and fight for a future that both frightens and calls to her.

This sweeping fantasy romance inspired by Cinderella and a Chinese fairy tale is the first in a breathtaking new series by the acclaimed author of Daughter of the Moon Goddess.
