Twin sisters from Holland, as divergent in temperament as they are in ambition, are given a trip to London as a graduation gift. The lighthearted fun-loving Micke meets and falls in love with a Dutch journalist who eventually returns to his native land to marry her. Tobi, up against the proverbial choice between career (as a concert pianist) and marriage to Evert (a young musician with old fashioned ideas) realizes that the piano is an of herself. Tobi's tour through the great cities of Europe gives Evert time to contemplate his loss and compromise his ideals -- happily for himself and his lady fair. Through visits and reams of correspondence, shared with the reader, the sisters keep in touch. The perpetual goodness of both girls, the sugar coated treatment of their problems, and human relations and the author's verbiage in place of action keeps the plot moving at a slow crawl. There are some warm and humorous passages, but the book and its heroines seem a bit naive for this age group.
