When Tom's grandfather goes off the road, Tom is sure Gandy has gone mad. Tom knows that beyond the wall lies the Outside, a wild place filled with barbarians and unimaginable dangers. He also knows that Oldies are weak-minded. So Tom summons all his courage and goes after Gandy, who obviously doesn't know what he's doing. Or does he? Tom's experience in the strange, messy, emotional world Outside, where so many things prohibited to Insiders are taken for granted, quickly shakes all his certainties. Who is crazy, the Oldies who are sent to the Memory Theme Park, or the families who let them go? Is the Wall meant to keep the Outsiders out, as Tom has always been told--or the Insiders in?
(from the publisher)

In 2040, eleven-year-old Tom follows his grandfather through the Wall and into the forbidden Wild, where they seek to find his grandfather's boyhood home.
