When Andrew invents a shrinking machine that sucks space out of atoms, things backfire, and he and his cousin end up smaller than fleas and climbing over the head of a dog. His miniature robot provides them with facts about fleas, a dogÆs nose, and its smelling ability. The uninspired story is not resolved, however, but will be continued in the next volume. Cartoonish black-and-white illustrations accompany the text. (c) Copyright 2010. The Horn Book, Inc., a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
