Son of the Mob by Gordon Korman
Vince Luca's dad is a mobster - a big boss. Vince has got it made. Girls, cars, guns - whatever he wants he can have. Except he doesn't want it. Vince wants to be normal. He doesn't want to live in a house where he can't talk because the FBI have got the entire place bugged, where he finds his mom digging bullets out of his dad's mates in the bathroom, and where he gets dragged off by the police because his birthday present's stolen. But it's not easy going straight when your entire family thinks you're crazy.
