A seventeen-year-old San Francisco girl learns, on a Caribbean cruise, to abandon her defensive provincialism. It is with distinct displeasure that Ryan faces a three week trip with people who are not only in a different age category, but heaven forbid, are ""furriners"". Sight seeing, romance, and friendship, welded together by the cameraderie that inevitably springs up on shipboard, clear Ryan's vision, and she realizes that it is a vast, rich world into which she has been born. Pauline Coleman, whose The Different One, received the Dodd Mead Librarian Prize, handles her teen-age heroine with incisiveness, daring to expose in her both that which is attractive and that which is petty. Consequently, Ryan is considerable more persuasive than are those faceless creatures who populate the average teen-age novel. The details of the cruise, (The Dominican Republic, Trinidad, Caracas, Jamaica), itself, are also convincingly handled here.
