I love this book!  The illustrations are cute and full of personality. The story is a celebration of words, a celebration of daring to venture beyond our comfort zones to explore the wider world, a celebration of books.  A little mouse who has been raised in a nest of torn words watches his siblings leave home to make their way, but has no desire to do so himself.  When pushed off by those who love him, he sets forth looking very Indiana Jones-ish, to discover the world is full of more words, and he becomes a seeker of words, even when it means braving the beastly cat, but in the end it is the cat who shows him the world of words to be found inside books.
