The declaration ``Sweet wonder!'' ends this book—an apt assessment for an uplifting story from Cowley (The Mouse Bride, 1995, etc.) and Gilchrist (Madelia, p. 1304, etc.). Drought has struck Brianna's town, and the grown-ups gathered on the porch of Mr. Williams's store, usually ``good and kind neighbors,'' are ``getting real scritchy with each other.'' Something's got to change or the corn will die. The possibility of that change roars into town in a pickup truck, a woman with a ``smile so big, it used most of her face,'' who specializes in rainsong. The adults don't take her seriously, but Brianna can smell the coming rain. She joins the woman in singing; the other children follow, as does Brianna's mother. The rain begins, and only Brianna notices the woman leave. A universal message reaches out of this warmhearted book. (Picture book. 5-9)
