Music has the capacity to make friends of enemies, in this quiet study of one introverted fellow: Mole. Mole spends his days alone in his underground hovel, until one night while eating supper in front of the television, he hears the sweet sound of a violin. “I want to make beautiful music, too,” Mole claims, then sends away for a violin of his own. One note leads to another, and his music goes from screeching to symphonic. Unbeknownst to him, his years of underground practice have overarching effects, seen by readers only in the illustrations. Lilting strains of music attract birds, farmers, presidents, and queens. Mole’s subterranean world, a realm of permanent night, is softly lit by glowing umber, while outside, fighting armies lay down their arms as the music plays on. With endearing characterizations stylistically akin to Arnold Lobel’s Frog and Toad, the beloved Mole will easily win the affections of readers and inspire young hopes for a better world.
