Amanda McCready was four years old when she vanished from her blue-collar Boston neighborhood. Patrick Kenzie and Angela Gennaro risked everything to find her, only to orchestrate her return to a neglectful mother and broken home. Twelve years later, Amanda, now sixteen, is gone again.

Still haunted by their consciences, Kenzie and Gennaro must now revisit the nightmare that once tore them apart. Following the trail of a lost teenager into a world of identity thieves, methamphetamine dealers, and Russian gangsters, they once again put everything that matters to them on the line in pursuit of an answer to a troubling question: Is it possible to do the right thing and still be dead wrong?
