One of my absolute favorite books. It manages to deal with several serious subjects in an irreverant, nonscary, and teen friendly way- quite an accomplishment!
Almost sixteen year old Drew and his younger sister Steph are disappointed to be sent on a Scandinavian senior citizens' cruise with the star of the program- the grandmother they have never met. After meeting the dance instructor- the gorgeous Holly, Drew decides the summer may not be as hopeless as he first thought. ( )
