But on the horizon is a new and even deadlier foe, a powerful prophet determined to help the Richters bring about the end of the world. And even worse, the prophet's daughter is someone painfully close to Daire...Dace's ex-girlfriend, Phyre. With the odds stacked against her and foes at every turn, will Daire survive long enough to create the future she desires with Dace, and will love truly be enough to conquer all?"
