The little boy, all decked out in mackintosh, rain hat and boots, looks prepared for something tougher than this fragile fantasy about his search for a rainbow and the games he would play with it if he found it. The full-size, water color and pastel illustrations are bright and attractive. Especially well done is the coloring of the sky and landscape during the heavy thundershower, and the turbulence they suggest helps to balance the sweetness of the story for the boy returns home to find the rainbow in his room and the scenery becomes flooded with inspirational-looking sunbeams.
