While ultimately it may not entirely work as story or history, Krebs offers a glimpse into a part of human culture most youngsters—or oldsters—may not know at all. In rhyme, she tracks China’s Silk Road, evocatively used these days as a metaphor for all kinds of cross-cultural memes, as a kind of exotic school chant. There’s a running chorus, “We’re riding on a caravan, a bumpy humpy caravan,” and there’s the first-person plural narrative, also rhymed, from Xi’an to Kashgar as silks are traded for wool, rice for bread. The yearlong trek ends at Kashgar’s Sunday market, which still exists today. The colorful pictures, made with bits of silk brocade and marbled paper collage as well as watercolor, show many kinds of costume and many ages and genders of caravan travelers. The pictures are busy with animals and wagons, desert and mountains. Author’s notes cover some background, but no sources are given. Adult readers will probably yearn for more information, but children will enjoy the bouncing rhythm and the intricate images. (Picture book. 5-8)
