It will be the rare girl who will be able to wade through the 320 pages of this teen age novel about a beautiful -- let's admit it -- a beautiful, very hardworking grind. Constancia Lona, South American girl of good parentage, whose talented and cultured family has been reduced in economic status, wants nothing so much as to get a scholarship to a United States university. Ecuador with its revolutions and strivings, its eager young people and its ancient heritage of many cultures, is her home. Her charming friends include wealthy Graciela and her impulsive, romantic brother who falls in and out of love quickly, John Wentworth, who is on an exchange scholarship and pays his earnest way with solid talk on international sympathy that is superior to narrow patriotism -- they are nice young people but--. Our heroine is so beautiful and so earnest that readers will find it difficult to forgive all her virtues. The romantic adventures, the sight-seeing trips, and the many places of interest described will, however, be fresh material to those who attempt the book.
