In this deadly endgame, the final move is hers . . .
In America, the Registry weds girls to the highest bidder and raises boys for its army.
Mia Morrissey escaped to make her life her own, and now that she has, she will risk everything so that everyone can be free.
Going undercover as part of a diplomatic mission, Mia returns to America. But life there is more dangerous than ever as the walls grow taller, and the forgotten country faces its most ruthless leader yet, Grant Marsden . . . a shadow from Mia's past. With the help of Andrew, Carter, and other members of the subversive group Affinity, she embarks on a perilous journey to defeat Grant, bring down the government, and destroy the Registry once and for all.
But when a terrible betrayal exposes the operation, Mia discovers that her enemies have used her—and so have her friends. Alone and frightened, she's uncertain of whom to trust—or whether the mission is worth the sacrifice.
With the fate of her friends and the future of her country on the line, Mia knows that her next step may be the last for her . . . and America.
