The Case of the Myface Kidnapper — Franklin W. Dixon

Frank and Joe's latest case involves the dangerous underside of social networking. A football friend from a nearby school contacts the Hardys when a team member goes missing! One minute he was at a massive beach party that everyone from school was invited to via MyFace; the next moment he was GONE! The MyFace parties continue, but so do the crimes: robbery, kidnapping, car theft...can murder be far behind? Is MyFace a social network of friends or a network of something far more sinister?
