The greatly anticipated final book in the Change series. In a world of mutant powers and deadly creatures, one small town faces its worst nightmare...

In a single shocking night, Las Anclas is conquered. Voske rules the town, remaking it in his image. He brings Opportunity Day to Las Anclas, with its terrifying lottery of "Change or die." He forces Paco into the role of his son and prince, always watching him for signs of rebellion. And for those who escaped his net, he sends elite Changed soldiers to drag them back to be executed.

Inside Las Anclas, Paco and Becky play a nerve-shattering game of cat and mouse, plotting a resistance under Voske's eye. Outside the walls, Ross, Mia, Jennie, and Kerry desperately evade pursuit and try to free their town. And Felicite, alone, must face the choice she's given up everything to avoid.

In the darkness of defeat, can hope catch fire?
