A desperate child escapes from hiding only to face new dangers in the New York Times–bestselling author’s near future YA adventure series.

In a world where the Population Police wield terrifying power, Luke Garner is an illegal third child. After spending his entire life in hiding, he’s found a way to escape—by assuming the identity of a deceased child. But living among other people isn’t going at all how he imagined.

Luke now attends Hendricks School for Boys, a windowless building with cruel classmates and oblivious teachers. He knows he has to blend in, but he lives in constant fear that his behavior will betray him.

Then one day Luke discovers a door to the outside. He knows that beyond the walls of Hendricks lie the secrets he is desperate to uncover. What he doesn’t know is whom he can trust—and where the answers to his questions may lead him.
