Trouble Comes Back — Keith Snyder

Jason Keltner and his buddies Martin and Robert have moved from the manor to a house in Venice, but they're still in Southern California, a place as much a mindset as a location, with a worldview and lifestyle all its own.
Donna Cooper is the daughter of a drugged-out rocker called Uncle Trouble, and someone is threatening to kidnap her. The only person Donna seems to trust is Robert, and the only people he trusts are Jason and Martin. The three of them have to protect the little girl in a world in which everyone else is suspect and family values have little to do with innocence.
