Twenty-two-year-old Aern is done watching his brother destroy the only thing that matters. He never wanted to take Morgan’s place among council, never wanted to rule their hidden world. But when the key to the prophecy is found, a young girl named Brianna whom Morgan will destroy, Aern knows he has to take action. What he really wants, is for things to go back to normal. But now he’s kidnapped a girl, and his brother’s men are after him. His only hope is to join with the Division, but they have plans of their own, and it’s the last thing Aern is willing to do. Emily just wants her sister back. She doesn't care about the prophecy, or realize what’s at stake. But when she goes after Aern, the truth of the matter uncoils, and Brianna isn't the only one who’s in danger. Suddenly, they’re at the center of a secret war, and unless they can work together, they’ll both have a sacrifice too big to make.

According to prophecy, Brianna Drake was born to save the world. The trouble is, she doesn't have the slightest idea how. Her visions should have given her the answer, but they’re beginning to shift, making the danger too unpredictable, even for a prophet. If she can just help her sister restore their hidden powers, she might be able to stop what’s coming. But an old enemy returns, and he’s got plans for Brianna and her visions. What neither of them knows is that fate has given a stranger one chance to find her. He was trained to protect the chosen—but if he fails, the future will crumble.

Brianna can see her future, but it's the past that haunts her. Plans laid in place centuries ago are threatening not only her and her sister, but all of the Seven Lines. As the shadows plot their way to old rule, the visions shift again. Her power has led to some hard choices—and the occasional stab wound—but this set of futures holds nothing but darkness. Unable to bear the idea of losing the footing they've so recently gained, she turns the soldiers of the Seven. But with shadows hidden among the ranks, can she overcome the path they've set in place, or is she blindly following their lead?
