A fine counterpoint of wistful ache and be-bop sparkle informs this story about shaking the blues. A girl wakes to an urban morning, her elemental funk reflected in the lonely, sagging laundry line seen across the street from her window. “That’s such a sorrowful line./It’s droppin’ down so lowly/even pigeons pass it by.” Her bubbly sister will not let her mope and tries a little jazzy word music: “Sweet potato!/Rutabaga!/That’ll work fine!/We can play together/with the laundry line!” Her persistence pays off—it’s not long before that piece of rope has been transformed from a study in malaise to a Double-Dutch four-step workout. Davenier’s watercolors are charmingly atmospheric, perfectly suited to Millen’s spirit-raising verse; the two will work magic on any down-at-the-mouth child. (Picture book. 4-8)
