Allyson Braithwaite Condie
Matched trilogy volume 3
In search of a better life, Cassia joins a widespread rebellion against the Society, where she is tasked with finding a cure to the threat of survival and must choose between Xander and Ky.
Chasing down an uncertain future, Cassia makes her way to the Outer Provinces in pursuit of Ky--taken by the Society to his certain 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.
