Hannah Smart is the happiest she's ever been. She's doing great in school, she's got her own spot on the Friday evening news, and she's desperately in love with the boy next door. But when Hannah's boss asks her to be part of a treasure-hunting reality show for teens, she instantly feels ill. For most kids, a high-seas adventure searching for treasure would sound amazing, but for Hannah, who suffers horribly from seasickness, it's a total nightmare. When she finds out that her crush and the more perfect than perfect Piper Steele will both be there, she has no choice, and agrees to the trip. In true Hannah fashion, she comes up with a plan to overcome her fears once and for all. What she doesn't know is that Piper has a cunning plan as well, which means stormy seas for Hannah Smart.
