USA Today bestseller For five centuries, a witch’s curse has bound the trolls to their city beneath the ruins of Forsaken Mountain—time enough for their nefarious 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 de Troyes is taken beneath the mountain, she learns there is far more to the myth than she could have imagined. Cécile has only one thing on her mind after she is brought to Trollus: escape. But if she is to succeed, she must bide her time and find a way to outsmart the clever, fast, and inhumanly strong trolls that hold her captive. But while awaiting the perfect opportunity, Cécile unexpectedly falls for the enigmatic troll prince to whom she has been bonded and married. Their love gradually changes her perspective, opening her heart to new friends and opening her eyes to the hardships of the enslaved half-troll, half-human creatures of Trollus. As rebellion brews and the political games of Trollus escalate, Cécile becomes more than a trapped father’s daughter. She becomes a princess, a witch, and the hope of a people—someone who has the power to change Trollus forever.
