Conclusion to the New York Times bestselling Matched trilogy! Cassia's journey began with an error, a momentary glitch in the otherwise perfect façade of the Society. After crossing canyons to break free, she waits, silk and paper smuggled against her skin, ready for the final chapter. The wait is over. One young woman has raged against those who threaten to keep away what matters most—family, love, choice. Her quiet revolution is about to explode into full-scale rebellion. With exquisite prose, the emotionally gripping conclusion to the international-bestselling Matched trilogy returns Cassia, Ky, and Xander to the Society to save the one thing they have been denied for so long, the power to choose.
