Barner's idea is a good one: to use Paul Revere's ride to teach map skills. He uses a team of mice to illustrate how Revere got from his home in Boston to Lexington; the mice have to avoid their enemies, sinister rats who break bridges and turn signs around. However, Barner never quite explains who Revere is, nor why the ride is famous, until the author's note at the end. Rich colors, silhouette figures, and jazzy graphics draw readers in and bring some order to the confusion of the opening pages, which offer no context for the two lights at the Old North Church (the text begins on the title page) or any sort of date or historical milieu. A final section encourages children to attempt their own maps; it will be up to adults to flesh out the innovative, but bare-bones discussion.
