USA Today bestseller and finalist for the Goodreads Choice Awards for best debut.

SOMETIMES, ONE MUST DO THE UNTHINKABLE...

For five centuries, a witch's curse has bound the trolls to their city beneath the ruins of Forsaken Mountain--time enough for their magic to fade from human memory and into myth. But a prophecy has spoken of a union that will set the trolls free, and when Cécile is stolen away to fulfill it, she enters a world that is both magical and deadly.

Cécile has only one goal after being bonded to the prince of the trolls: escape. Except while awaiting the perfect opportunity, she discovers there is more to the mysterious crown prince than anyone realizes.

As rebellion brews and the political games escalate, Cécile becomes more than a farmer's daughter. She becomes the hope of a people--someone who has the power to change Trollus forever.
