A charming modern fable. Avon the snail's voracious reading convinces him that having an adventure is the key to a happy life so he sets out on a journey with his new friend, Edward the ant. In a series of very short chapters, the two travel–at a snail's pace–the length of a branch, meeting another snail, a caterpillar, a worm, a cricket, a salamander, and a mouse (whom Edward and Avon are sure is a dragon in disguise).
Many insights unfold: "here" and "there" are not much different; while getting lost is easy, it's finding one's self that's hard; whether rushing or going slowly, one still arrives; and it is important to look at the world with one's heart and not just with one's eyes. The book is full of plays on "beginning" and "end." Until Avon and Edward help the worm, he is unsure which is his front and which is his back, and is doomed to a life without end. When they reach the end of the branch, are they actually at the end of the sky and the beginning of the branch?
Avon and Edward turn around and head back, coming to a house that looks magically like Avon's own. The friends decide to live together in this magic castle. And so, true to the book's title, the beginning of their friendship ends. Whimsical pen-and-ink sketches add much to this wise little book.
