Faker by Gordon Korman

From the #1 bestselling author of Restart, the story of a family of liars... and the son who wants to break the family tradition.

Trey knows the drill: His dad gets him into a school full of kids with rich parents. Trey makes friends, and his dad makes connections. Soon, there's the con, where Trey's dad suckers the other parents into investing in one of his schemes. Once the money's in the bank, Trey, his sister, and their dad are on the run... until they set up somewhere else and start again.

Trey believes his father when he says no one's getting hurt. After all, these parents have money to spare.

But Trey's starting to get tired of running... and lying... and never having a friend for longer than a few months. But how do you get your family to stop lying when your lives depend on it?
