What is striking about this book, "Johnny and Jo Grow Up...", is the lightness with which the author manages to deal with interpersonal relationships between children. We know how difficult it is to penetrate the child's soul, yet Margherita naturally investigates the motivations that lead children to perform certain actions, their affections, their disappointments, and seasons it all with the constant presence of Jesus, who is exalted in every episode, big or small. A valuable book not only for children but also for Sunday school leaders and all parents who wish to talk to their children about the things of God in a clear and simple way.
