Spring break is a string of firsts for 14-year-old Charlie Hudson: first cruise, first kiss, first time kidnapped by hijackers. After a hijacker knocks him unconscious, Charlie comes to in a lifeboat full of kids adrift in the Pacific Ocean. Charlie must survive mutinies, sharks, killer storms, and drug runners. Back in the U.S., rogue government agents who hired the hijackers are coming after him, but they have no idea who they're messing with. With Kevin, his new best girl, and Sam, his side-kick, Charlie, the invisible boy, is transformed into a full-blown hero.
