"Mia's made it to Mexico with Carter and Andrew-but it's not the Promised Land they hoped it would be. Carter is grieving his father Rob's death, and Andrew is distant. When the young men are captured by rebel forces, they become reluctant recruits in the underground militia, rather than be deported to certain death. Grant, the "husband" back home who bought Mia to be his lawfully wedded his wife, is instructed to stand down by the Registry. But he nonetheless persists in his pursuit, and approaches Carter with a deal to swap his father Rob, presumed dead, for Mia. Before Carter can act on this proposal, Mia helps him and Andrew escape the militia. The three of them disappear into Guatemala, where they join a group of American refugees. There Mia finally meets her covert ally S, the young woman who helped her escape the Registry. S turns out to be a 21-year-old runaway, Frank and Al's daughter Steffy. She and Andrew are both appalled when Mia confesses that she was the reason Steffy's fathers were captured. Driven by the need to redeem herself, Mia announces that she's going back to destroy the Registry"--
