‘The War That Changed Rondo’ is a book about the fact that war has no heart and understands no language, but touches everyone and leaves scars on everyone. But if we build a machine of light together and learn to sing despite everything, then even the most fragile creatures will be able to stand and win. And this book is an occasion for a thoughtful conversation with children (or with yourself) about what is currently happening in the country or elsewhere in the world, in the format of a magical story that always leaves room for hope and optimism.
