Two new volumes in the Wheels at Work series are for youngsters ready for the next step in big-vehicle obsession. Kilby offers up a variety of scenarios and unique details about working machines, without talking down to his audience. For instance, the reader learns from In the City, which focuses on urban vehicles such as armored trucks and moving vans, that in order to squeeze into tight alleyways, drivers of delivery trucks fold in their rearview mirrors. In the Country (1-55337-472-X) reveals that a livestock trailer can hold up to 40 cows or 100 pigs. It looks at vehicles that work on and around farms, including feed trucks and combines. As the author introduces each truck, the lettering appears in bold type, making it pop out of the text. The acrylic illustrations are sophisticated, realistic, and beautiful. No frivolities here—this pair will be the ultimate ride for the young expert of all things wheeled. (Picture book. 4-7)
