Some people move through the world making noise. Thirteen-year-old Leo has learnt to be still. But when an old illustrated book vanishes from the bookshelf, Leo discovers something extraordinary living in the walls of the Victorian house: the Snibbit, a small magical creature that collects beautiful things and understands that silence can be full of meaning. Through carefully preserved fragments from the past, the Snibbit teaches Leo how to navigate a world that isn't built for quiet people.

Is about Alex, a young man with dyspraxia, whose mother, Marianne, invents a system of symbolic objects—"Checkpoints"—to help him manage his daily transitions and behaviour.
