With softly shaded black and white drawings and brief text, this slim book explores the symbiotic relationship between the yucca and the yucca moth. It is a relationship as fantastic and surreal as the desert landscape against which it is set. Hauth's words are precise and lyrical, evoking the magic of this endlessly repeated story, and taking the young reader on a journey through the sometimes capricious seasons of the desert southwest. Teachers will appreciate the additional information in the back-matter. Kids should find Sather's insect and bat close-ups most appealing.
