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.

A boy follows his cat into a magical market that trades in feelings. After trading away his shame to reclaim a keepsake, he must decide whether to keep his memories—even the painful ones—or hand them over.
