The Lost Boys by Craig Shaw Gardner
A mother and her two sons move to a small coast town in California.
The town is plagued by bikers and some mysterious deaths.
The younger boy, Sam, makes friends with two other boys, the Frogg brothers, who claim to be vampire hunters.
Meanwhile the older boy, Michael, is drawn into the gang of bikers by a beautiful girl named Star.
Michael starts sleeping days and staying out all night while Sam starts getting into trouble because of his friends’ obsession.
