Parallel adventures unfold in this unique book that holds two stories in one! Meet Walter the mouse, who conquers the twenty-six cats that stand between him and the outside world, and - when readers turn the book upside down and back-to-front - meet Liam the boy who conquers the twenty-six letters of the alphabet so he can read Walter's tale.

When these two stories meet in the middle with Walter outsmarting the cats, and Liam learning to read, the two protagonists enter each other's world.
