Young Ricardo Perez proves himself when he takes over his father's job as road tender in a Puerto Rican mountain village, when his father is hurt and has to be hospitalized. An apparently untrainable horse which Ricardo loves and cherishes, although the family cannot afford to feed an animal which does not contribute to the family income, is Ricardo's great worry. Patience seems wasted until the horse helps the family through the emergency of getting father to the hospital. A prize for the best road tender, with a special prize for Ricardo, makes another focus of interest. All in all there is a great deal of incident and detail for this age level. The characters are warm and true, and the author has created a sense of another land -- foreign, but familiar and American. This book can have special importance for large cities like New York where there are minority problems. A real contribution to understanding between racial groups without caricature or sentimentality.
