Rules are different outside the society. Chasing down an uncertain future, Cassia makes her way to the Outer Provinces in pursuit of Ky--taken by the society to his sure death--only to find that he has escaped into the majestic, but treacherous canyons. On this wild frontier are glimmers of a different life and the enthralling promise of rebellion. But even as Cassia sacrifices everything to reunite with Ky, ingenious surprises from Xander may change the game once again.
