In a town cleanly divided by a long wooden fence, the rules have always been clear. Clover, a young Black girl, has been told by her mother never to climb over to the other side because it is simply not safe. On the other side lives Annie, a young white girl, who is given the exact same strict warning by her own family. Day after day, the two girls sit near the boundary, watching each other with quiet curiosity but never crossing the line. But as the long summer stretches on, the unspoken barrier begins to feel silly. Slowly, bravely, the girls decide to sit on top of the fence together. Through shared smiles and simple conversations, a beautiful and defiant friendship takes root. This deeply moving story powerfully demonstrates how the innocence of children can break down the deepest walls of prejudice and division.
