Fiona Sweeney wants to do something worthwhile with her life, so she volunteers to travel to Africa and run a bookmobile. She favors one community in particular, Mididima. But many people in Mididima resent this "white woman" and the bookmobile in fear their children will forget tradition. When some of the books borrowed from the bookmobile by a Mididima boy are not returned, Fi is ordered to discontinue her visits to Mididima. She is determined to find the books and continue her work there.
