A lively story in which all the illustrations are tangrams; the well-known geometrical puzzle that is a square cut into seven pieces arranged to make various other shapes. It is also a delightful story about the imagination where the words and pictures combine to tell a deeper story about the idea of self, from the highly acclaimed creator of I See, I See.
