This is the story of a revolution carried out in anonymity with a bodkin as its only weapon and a boy as its hero. The youngest son of the Brailles, a family of leatherworkers, has an accident that causes him to gradually lose his sight. His tenacity and that of the people around him leads to a string of adventures and discoveries that take them much further than we could ever dream. The life of Louis Braille, which tells us of light and shadow, freedom and oppression, health and illness, of how ingenuity can compensate for lack of resources, unfolds in parallel to the turmoil of early 19th century France, an era of uprisings and hope.
