Isaacs and Zelinsky tell an even taller tale about Angelica Longrider, the outsized heroine of their hilarious, Caldecott Honor-winning Swamp Angel. Having outgrown Tennessee, Angel moves to roomy Montana, where she faces a wild dust-devil horse and a bandit named Backward Bart, born so ugly that his mother rolled him around backwards in his stroller. He walked, spoke and robbed backward ever since. Bart's garbled threats remain funny even after several readings. "Cash your gimme!" just doesn't get old. Side-splitting similes abound as well; Bart's nefarious cronies are "pricklier than porcupines in a cactus patch." Singsongy, colloquial narration guides readers from predicament to outlandish predicament with humor and folksy charm. Angel's antics, pictured in oval and rectangular panels and surrounded by rippling wood grains, neatly explain the topography of the West in traditional folk-story fashion (wrestling the bucking bronco, Angel's feet drag across the ground, creating the Grand Canyon). Zelinsky's rustic oil illustrations offer a gallery of comic faces, frozen in exaggerated surprise, shock and frustration. Artfully crude, comedic artwork, friendly, understated narration and a wildly hyperbolic story combine to create a new classic. (Picture book. 4-10)
