From the publisher:
Papa will not allow Clara to learn to read--he says "Farm people like us do not have time to read." But when the traveling bookwagon, with persuasive Miss Mary at the reins, arrives at their farm, Papa realizes he must change his mind. Based on the true story of America's first 'bookmobile.'
