On one of the hottest weeks of the summer in Caliente, Texas, best friends Elena and Alma open competing snow-cone stands across the street from each other. As business booms and wanes, the competition gets stronger, as do the sales pitches and incentives. Extravagant decorations, puppet shows and folk dancing in traditional costume cause ever more customers to crisscross the street, until both ice machines simultaneously malfunction, pouring out colored ice shavings until a slushy rainbow ribbon of the stuff tumbles down the street, encouraging everyone to “[cascade] down the dazzling icy mound” and leaving Elena and Alma to dissolve their rivalry and renew their friendship. The full-color paintings are mostly realistic, featuring appealing, if stiff, protagonists; the rainbow-colored snow-cone slide makes for a startling and unconvincing intrusion. Lacking the charm of Strega Nona and her magical spaghetti pot, this summery, bilingual story jars with the quick flight of fancy. While the themes of friendly rivalry and work-made-fun are worthwhile, the odd deus ex machina mystifies more than it delights. (Picture book. 5-7)
