The always-interesting Browne adds a bit of Central American ambience to his typically British setting. Billy, hair parted, in gray-flannel shorts, is a worrier. In imaginative, almost surrealistic ink drawings, Billy worries about hats, shoes, giant birds. When he worries about rain, the picture shows him in his bedroom, floating on waves of water. His parents try to bolster him, but it's not until he stays at his grandmother's house that help appears--in the form of several brightly colored Guatemalan worry dolls. At first they help Billy sleep, but then he starts worrying that he has given the worry dolls too many worries. His creative solution is to make little dolls for the little dolls. The story is slight, but the pictures are amazing. In counterpoint to the monochromatic worry scenes are pictures so vivid and colorful, they ease concern and spread cheer with each turn of the page. Children will enjoy looking at the multiplying personal dolls and may ask for some of their own. A short note explains their genesis. Ilene Cooper Copyright © American Library Association.
